Today (May 9) is the average last frost date in our area, and Mother’s Day is the traditional Colorado date considered ‘safe’ for planting.
Of course, we have lived through enough late-May freezes and snowstorms to be a bit cautious! We offer vital supplies to have on hand to protect your frost-sensitive plants. Ask about our row-cover fabrics when you come to the nursery.[Read More]
We’ve just endured one of the coldest and snowiest winters in the last 16 years.
On December 22nd Boulder saw low temperatures of minus 24 degrees Fahrenheit, followed by minus 10 on January 30th , and again in late February the temperature fell to minus 11. These cold temperatures seem to be the explanation for damage to plants that we are seeing.[Read More]
We have recently received a veritable avalanche of excellent well-written, regionally appropriate books about a wide range of gardening approaches, soils and plants, and more are on the way!
Voting for the Planet, and People
With the election a week away, we wanted to bring a visionary moral community effort to your attention. Over 30 of our local environmental groups are calling on Denver municipal candidates to work for the planet, and people.
This coalition has created “The Greener Denver Platform” for a healthy, thriving and climate-resilient future.
And now for the surprise! Just when you thought the gardening season was over, and that Harlequin’s Gardens has gone into winter hibernation until March 2024, we have a surprise for you! We will be open for 2 Saturday Pop-Up Markets, on November 11th and 18th from 10am to 4 pm!
Our earlier fall weather was so mild and beautiful that many of you weren’t ready to think about planting bulbs for spring flowers, let alone holiday gift giving. So these pop-ups will include lots of bulbs on sale (see below), and some of the CURATED ARTISANAL GIFTS we offered at our Holiday Gift Market, now 25% to 50% off.
We know that not all of customers live in a house with a yard. Many of you live in apartments or condominiums or townhomes and have only a balcony or a very small patio on which to grow anything outdoors. We would love to help you make the most of your outdoor space, even if it’s tiny.
Some customers wonder why we are selling starts of self-sowing hardy annuals like Larkspur, Rocky Mt. Beeplant, California Poppy, Peony-flowered Poppy, Sweet Alyssum and Desert Bluebell. Shouldn’t they be grown from seed sown directly in the garden? The answer is Yes, they certainly can be, and if you find a source for the seeds and sow them at the optimal time, usually in the fall, you can get great results. But some gardeners report having little or no success with direct sowing: their timing is off, the seeds are watered in and then dry up and are no longer viable, critters eat the seeds, etc. [Read More]
Every 5 years or so Congress has the opportunity to transform our food system by revising a piece of legislation known as the Farm Bill, which covers everything from supporting farmers to ensuring food security for all. Politicians and local and national advocacy organizations are working to determine how nearly a billion dollars a year will be spent. You can help!
A Few New & ‘New Again’ TOMATOES: Offering 73 varieties!
BURRELL’S SPECIAL – New Again! 70-75 days, Hybrid, Determinate
A very productive and ‘picture perfect’ large red salad/slicer tomato developed by Burrell’s seed company of Rocky Ford, CO. The flattened globe fruits average 8 oz, 3” x 2.5”, and have excellent sweet, balanced flavor, plump, meaty texture and small cores, good heat tolerance, and demonstrated ability to set fruit in hot weather. Vines grow to 4’.
CASCADE VILLAGE BLUE – New Again! 75 days, Open-Pollinated, Indeterminate
This lovely indigo saladette type tomato holds well on and off the vine, is beautiful, and tastes great, too. Dark purple-skinned, 3 oz globes ripen to red on the bottom, with a red star shape that forms under the calyx, common to indigo tomatoes. Flesh is red, foliage has a dark purple tinge.
Dr. WYCHE’s YELLOW – New Again! 80 days, Heirloom, Indeterminate
Dr. Wyche’s has been away too long! One of the great heirloom tomatoes featured in Dr. Carolyn Male’s book ‘100 Heirloom Tomatoes’. The yellow fruits are large (up to 1 lb), slightly flattened globes, with very richly flavored flesh , fruity and complex, meaty and blemish-free. When completely ripe, they are golden-orange.
FLAMING BURST – New! 70 days, Open-pollinated, Indeterminate
These crack-resistant, 1oz, 1.25 x 1.75”, golden orange fruits look like a cross between a pear tomato and a cherry tomato, in clusters on a steadily productive plant. Meaty but not dense; juicy and sweet but tangy, not insipid, with the flavor and nuance that so many yellow pears tomatoes lack. The high-yielding plants grow to a manageable 4′ tall.
JERSEY DEVIL– New! 85 days, Open-pollinated, Indeterminate
Jersey Devil is a brilliant red, very prolific heirloom paste-type variety shaped like a plump banana pepper. These sweet and richly flavored, 4 to 6” tomatoes are solid and very meaty, great for making into sauces and salsas, and even eating fresh, and have very few seeds. Vines grow 3’ to 5’ tall, , fruits can be colossal! They yield very heavily.
LARGE RED CHERRY – New! 75-80 days, Open-pollinated, Indeterminate
This famous 19th century cross between a smaller currant-type wild tomato and a domesticated garden tomato bears clusters of sweet, juicy, bright red 1″ to 1.25” diameter round fruits over a long season on tall, vigorous vines. Ideal for salads, stuffing, and snacking.
MOUNTAIN DELIGHT – New! 70 days, Hybrid, Determinate
One of the Mountain series developed by NC State University and similar to Mountain Fresh and Mountain Spring, but plants are more compact with higher yields. Bright red flattened globes weigh 10 oz. and are firm and flavorful, great for salads, slicing and sandwiches. Healthy determinate vines grow to 3 to 5’ tall and are resistant to many diseases.
ORANGE KING – New Again! 65 days. Open-pollinated, Semi-Determinate
One of the earliest full-size tomatoes to ripen and one of the best producers of tennis-ball-size, very meaty, bright orange globes that can weigh up to ¾ lb. Blemish-free fruit grow on stocky 3’ bushes that are easy to cage. An excellent short-season slicing variety, it has great low-acid, sweet, fruity flavor. This Orange King was bred by Tim Peters
PINK BUMBLE BEE – New! 65-70 days, Open-pollinated, Indeterminate
Recently bred by Artisan Seeds to perform under tough conditions, these gorgeous, streaked cherry
tomatoes hang in trusses of pinks, yellows and oranges. Vigorous, tall vines yield loads of crack-resistant fruit over a very long season; bright, sweet flavor; tolerates cool nights and hot days.
SUNRAY – New! 75 days, Open-Pollinated, Indeterminate The beautiful golden orange, blemish-free, 6 to 9oz fruits have a meaty texture and rich, sweet and tangy flavor, said to rival the best reds and perfect for salads, sandwiches, slicing or canning. Vigorous, leafy, high-yielding vines have strong resistance to Fusarium wilt. They are known to be very drought-tolerant and thrive in hot, dry climates.

Two quotations greet me every morning, posted on our bathroom mirror: “Tell me. What is it you plan to do with your one wild and precious life?” (poet Mary Oliver) and “I wake up each morning torn between a desire to save the world and a desire to savor the world. This makes it very hard to plan the day.” (author/editor E. B. White). The first inspires me to define my priorities, while the second, which perfectly describes my daily dilemma, allows me a little slack and sense of humor in the midst of my personal chaos and the chaos of life on Earth in this time. Perhaps you can take some inspiration and comfort from them, too.
Gary Meis teaching
Last Saturday a group of dedicated plantspeople came in from the cold to learn and volunteer with Harlequin’s Gardens’ expert propagator Gary Meis. We’re passing a few of his native plant seeding and propagation tips along to you.

Spring is here and the time is right for dancing in the garden – to stay warm!
You can also work up a mild sweat by beginning your spring clean-up. If you have not yet sheared back your cool-season grasses, like Alkali Sacaton, Appalachian Sedge, June Grass, Korean Feather Grass, Karl Foerster’s Feather Reed grass and other Calamagrostis varieties, now is the time. And if you have any Clematis vines that are categorized in Pruning Group 3, February and March are the best times for cutting them back to 1 set of growth nodes above the ground.
We’re celebrating all month, and we’d love to encourage you to support pollinators in your gardens.
Pollinator Month is a special time for Harlequin’s Gardens – a time when we celebrate the hard work of bees (honeybees, solitary bees, bumblebees) wasps, ants, flies and bee flies, butterflies and moths, beetles, some bats and birds, and some mammals. They’re all around us, connecting the dots between flowers and food.
Come check out our special pollinator display, which is our whole facility! The descriptive signage on most of our plants is marked with bee, hummingbird, and butterfly icons, and you might notice that almost everything is important to bees, of which we have over 500 species here in Boulder County alone. Even our native bunch grasses can provide nesting sites for bumblebees in the dried leaves at the bottom. [Read More]

Our shrubs are all given great care here at the nursery, but occasionally we find some that have a little damage or are sulking because they really want to get out of the pot and into the ground. To help them all find good homes where they will grow and prosper, we are bringing out these ‘seconds’ at substantially discounted prices. We will continue to bring out more as they sell.
Right now, we are offering: [Read More]

Sept. 6 thru 11 Enjoy:
In this period of high heat, we need to take special care of ourselves and our plants. Just as it makes sense to drink more water in the heat, it makes sense to water plants more often than usual. We water twice as much in July as we do in other months. BUT REMEMBER that plant roots need air, too. And if the soil is continually wet, plant roots won’t be able to use the water, and may rot. The best approach is still to water deeply, but not too frequently.
Hardy Geraniums are some of the most versatile an adaptable perennials for our area! Available in many colors and habits, they can be useful in sun and shade, moist and dry, as individual specimens, companion plants and ground covers.
These are not to be confused with Pelargoniums, the popular house plant, container and bedding plant Zonal “Geraniums” and Ivy “Geraniums,” which are not cold-hardy outdoors in Colorado. The name “geranium” is derived from a Greek word meaning little crane, hence the common name “cranesbill” which refers to the appearance of the seed heads. [Read More]

The Good News is that out of about 900,000 insect species currently living on our planet, only 1% to 3% are pests. We do not need systemic neonicotinoids (neonics) or any toxic pesticides to grow plants well. The solution is to employ human attention, biodiversity, nutrient-dense soils, application of nontoxic management, and tolerance.
The Bad News is that most people and most nurseries don’t know the good news. They believe the chemical companies when they tell us that we need to fear and attack insects and fungi as enemies. [Read More]
With great sadness, we share the news that the pioneering plantsman David Salman passed away on the fifth of June. David was a dedicated, passionate, and articulate educator and proponent of sustainable gardening, a plant explorer with a gift for selecting and introducing exceptional plants for western landscapes, and the founder of Santa Fe Greenhouses, High Country Gardens, and Waterwise Gardening.
Out of his serious concern for the planet, David had recently begun working on what he considered his ‘next act’ – helping to reverse climate change by enabling people to plant large numbers of trees, and especially shrubs. He wanted to identify the woody plants best adapted to conditions in the West and Southwest, and had solicited recommendations from Harlequin’s Gardens and others, with the aim of propagating and distributing on a large scale the most appropriate and successful plants for combatting climate change. David Salman’s legacy includes over 60 waterwise plant introductions. His contributions to gardening and gardeners in the West were transformational. He will be sorely missed.
The following tributes and obituaries for David are available: Nursery Management, AP News, and HaMakom. (Photo Credit: High Country Gardens.)
Bur Oak (Quercus macrocarpa) is a majestic, slow-growing tree reaching 60 to 70’ in height and spread, and is typically very long-lived (think 200, 300+ years!). It’s the sort of tree you plant for the benefit of the generations to come. Many oak species don’t thrive in Colorado’s alkaline soils, but Bur Oak is a happy exception. It is also drought-tolerant once established, even in dry clay, and can handle city conditions quite well. Bur Oak’s strong wood and strong, almost right-angled branch connections resist breakage in wind and snow. [Read More]
We are known far and wide for our selection of sustainable roses and for our expertise in helping people choose the best varieties for their gardens and landscapes. We sell roses on their own roots not grafted, which makes them more cold hardy, longer lived, with more flowers.
Below is a list of Roses we often have available.
We would like to invite you to visit the Boulder-Dushanbe Teahouse Rose Garden in downtown Boulder across from the city park. The unique treasure of an intricately handcrafted, traditional Tajik Teahouse was gifted to the city of Boulder by the citizens of Dushanbe, Tajikistan, one of Boulder’s Sister Cities, in 1988. In time, the design of the structure was amended to be able to house a restaurant business, construction was completed, and the Teahouse opened in spring of 1998. Both the inside and outside of this fabulous building are elaborately adorned with colorful carved, painted and sculpted elements, mostly traditional, plus some contemporary artistry.

Agave parryi in snow
As temperatures fall and the shortest day of the year approaches, most of us are taking a break from the physical work of gardening. But some of us are already beginning the seed-sowing process, following seed germination protocols for pre-treatment – from stratifying (exposing seeds to controlled cold temperature to break dormancy), scarifying (carefully sanding hard outer seed coats) to soaking in hot water or hydrogen peroxide solution, etc. At Harlequin’s, many of our growing-houses are full of seed trays or beautiful plants we potted up in the fall for spring 2023.[Read More]
At this time of year, when the weather is hot and mostly dry, it can be easier to establish transplants that already have a larger, deeper root system. Another very important factor in successful transplanting in this heat and drought is the quality of the potting soil the plant was grown in. Harlequin’s Gardens doesn’t use a commercial, lightweight, soil-less mix, designed for using chemical fertilizers and for minimizing shipping costs. [Read More]
In late June Eve and Mikl attended two inspiring events that are related in that both organizations / institutions are concerned with researching, trialing, and introducing plants that are resilient in the face of the challenges presented by Climate Change, especially increasing heat and long-term drought.

We have a large and diverse selection of perennials, particularly in larger quart and gallon sizes, that are ready for planting. (Photo: Sedum “Matrona”)
A FEW of our FEATURED TOMATOESWe’re excited about these tomatoes for this growing season!
We trial tomatoes for adaptation to Boulder growing conditions, and great taste.
CARBON – New Again! 76 days, Indeterminate. OP
This taste-test winning, hard-to-find heirloom is one of the darkest ‘black’ tomatoes, with delicious, rich, smoky-sweet, complex flavor; pretty 8-14oz. purple-brown fruits are resistant to radial cracking. Big, 5-7’ productive, regular-leaf plants are healthy and tolerate heat and dry conditions.[Read More]

BASTAN F-1 ANCHO/POBLANO – New!
65 days green, 85 days ripe (brown) from transplant, Capsicum annuum, F-1 hybrid
An exceptionally early and adaptable poblano pepper, Bastan plants are extremely high-yielding and robust, and produce big, thick-walled, very dark green, smooth, 4-6”-long, mostly two-lobed peppers that are easy to peel. Fruits may be used at the green unripe or chocolate brown stages. Excellent fried, roasted, stuffed, in chile rellenos or green chile sauces. 1,000 – 2,500 SHU. Plants have an upright habit with excellent leaf cover and concentrated fruit set. Fully ripe poblano peppers are traditionally dried and called Ancho.
TAM JALAPENO – New! – 70-75 days from transplant, Hyb., Capsicum annuum, 3,000 – 5,000 Scoville Heat Units
If you love the flavor of Jalapenos but can’t take the heat, perhaps the Tam Jalapeno is for you. Developed by Texas A&M, it was bred to be highly productive, disease-resistant, widely adaptable, early-maturing, thick-walled, and have great Jalapeno flavor with a lower level of heat – only 1,000-1,500 SHUs, much milder than the typical Jalapeno (3,000-5,000 SHUs). TAM Jalapeño can be made even milder by removing the thin membrane that connects the seeds to the wall of the pepper. Plants grow 2-3 feet tall and should be staked. They produce 3”- long plump dark green peppers with smooth, glossy skin. If allowed to turn red, they will be hotter. TAMs are great for mild salsas and dips, delicious added to salads, tacos or pizza, and great for pickling, jelly, and cooking. Try stuffing them with a variety of fillings for appetizers.

YANKEE BELL – New Again! –60 days green, 80 days red, OP, Capsicum annuum
A dependable open-pollinated sweet bell for Northern gardeners. Born on 3’ tall plants, the blocky 3-4 lobed fruits are medium sized and a bit smaller than hybrids but have good yields and better quality and uniformity than most OP bell peppers. Great for salads, stuffing, and cooking. Plants have stronger branches than other varieties.
CARIBBEAN HABANERO – New! – 90 days from transplant, Heirloom OP, Capsicum chinense, 400,000 Scoville Heat Units
Twice as hot as the common habanero! Its pungent, smokey, fruity flavor makes extra spicy salsas, marinades and some very intense hot sauces. The red pods are 2″ long and 1″ wide and grow on vigorous, bushy 3 – 4’ plants. It is so productive the plant may need support when loaded with fruit. We recommend wearing latex gloves and other protection when handling these peppers. With a heat level of 400,000 SHUs, these peppers are loaded with capsaicin which can cause irritation and pain when exposed to your eyes and even to your skin.
RETURNING FAVORITES: Anaheim, Early Jalapeno, Fish, Sheepnose Pimiento, Serrano Tampiqueno, Jimmy Nardello’s, King of the North, Marconi Red, Sweet Chocolate, Cubanelle and more!
We recently passed Boulder Valley’s “average last frost” date (May 9).With all this rain, it sure feels like Spring! Lots of gardeners are asking if it’s safe to prune now, especially roses and shrubs. The answer is YES! But…..
Pay attention to the characteristics of the particular shrubs and roses you’re thinking of pruning. [Read More]
Rock Garden Iris
It’s probably safe to assume you’re as anxious as we are to get our hands in the dirt, and happily, Harlequin’s Gardens is opening for our 31st season this Thursday March 2nd. We’re so looking forward to seeing you all again! We’ll have everything you need to get started for the season. Here’s what we’ll have available for you on March 2nd.
Our youngest gardener Baby Bonnie, with her Mother and Grandmother
This Sunday, May 8th we celebrate Mother’s Day! There are several different claims to the inception of the Mothers’ Day or Mother’s Day holiday in the US, inspired by ideas of helping less fortunate mothers, reducing infant and maternal mortality, voicing opposition to wars, and honoring motherhood. All of these share the common core idea of honoring Nurturers.
So even if you’ve never functioned as the mother of human children, you can still be a Plant Mom. When we prepare our soil, plant our seeds, keep them moist until they germinate, and give them the care they need until they are grown-up enough to fend for themselves (or require less attention), we are Mothering them. By planting for pollinators and native life-forms of all kinds, we are nurturing our ecosystem and helping to bring it back to balance and health.
This week, we invite you to visit us and choose some new plants to nurture and mother. And honor the Mothers in your life with the plants, garden items, books, classes or healthy products they’d love. We have a beautiful line of glazed pots for patios, entryways and balconies. Our organic pepper, tomato, and herb starts are pouring in, as are many new perennials and shrubs, roses, vines, grasses, and annuals, all neonic-free. We also have plenty of fruit trees and berry bushes, and seeds for delicious summer crops like beans, basil, cucumber, zucchini, pumpkin, and melon, and glorious pollinator-supporting flowers like Lace Flower, Poppy, Zinnia, Sunflower, Nasturtium, Gloriosa Daisy, Cosmos, Morning Glory, and many, many more!
We have a limited number of choice Peonies in 2-gallon pots, ready to make a long-lived presence in your garden! These varieties are different from the ones we will have in stock in a couple of weeks, which will be in 1-gallon pots.
Peonies are classic garden plants that add a lot of charm and beauty to the garden, increasing in size and beauty for many decades. Their gorgeous, fragrant blooms and lush foliage have made them popular for many years. When a peony is finished blooming, the attractive foliage mound makes a great seasonal ‘shrub’. And, of course, the sensuous flowers make stunning bouquets. Cut them when the buds have swelled and are beginning to open slightly. [Read More]
Okay, you prepared your soil and planted your vegetable garden with all kinds of wonderfully flavorful, nutritious foods, you’re watering and watching them grow, and wondering ….. When can I start to eat them, how do I harvest them, and how do I get the most out of these plantings? Here are some tips on vegetable crops harvest timing and techniques that may not be self-evident. Even if you’re a seasoned gardener, you may not be aware of some of these procedures! [Read More]
Our friend Mitten Lowe at Journey to Wellness is a fan of bone broth (with actual bones, as well as one that’s vegan) whenever the season changes. What’s more gratifying than taking fresh vegetables and herbs you’ve grown, or bought by supporting our local farmers, and simmering them for a fragrant, nutrient-dense health and spirit builder when the temperatures plummet?
