Our friend Clark has turned what used to be a family hobby into a full-time business. In his Longmont studio, he makes a delightful cast beeswax candles that come in a wonderful variety of shapes and sizes, including a number of designs that are cast in antique and modern European candle molds. In addition, we are offering Amber Lights hand-dipped beeswax taper candles and Hanukkah candles.
Amber Lights candles are highly decorative, wonderfully detailed, naturally endowed with a heavenly honey scent, and burn clean and smokeless.

Hanukkah begins Wednesday, December 14th. A set of dripless, smokeless, hand-dipped beeswax candles from Amber Lights contains all the candles you’ll need to light the Menorah through the entire 8-day holiday. And they smell wonderful! And they come in a lovely blue mesh bag. And they are Local. And if you have no use for Hanukkah candles, we have everything from birthday candles to 6″ pillars, bee-skeps to Buddha heads, Deco to dragons, reindeer to roses, all beautifully crafted from our friend Clark at Amber Lights.

Don’t be fooled by the title; a lot of the area covered is in Colorado, including Denver, Boulder and Ft. Collins. This is a very good plant ID book from by Mary O’Brien and Karen Vail with interesting descriptions. In addition, it’s an excellent herbal, giving both medicinal and edible uses. Highlighted in yellow are important “cautions”. It is presented in a respectful way honoring nature as did the Ute Indians who pioneered the use of these plants. For example, did you know that Gambel Oak “…is a good back country first aid plant to know, using the leaves as a poultice or wash for insect bites and wounds, or chewing a piece of the bark for toothaches….” Good photos. These local gals really know their stuff and we highly recommend their book!

Eunjoo Kang is a master ceramicist. Her work is rooted in the traditions of Korean art, inspired by the natural world, and shaped by a love for storytelling. Kang explores human emotion, spirit, and memory through clay and often draws on the textures and forms of nature, as well as the subtle expressions of the human face and figure. She shares, “Through my art, I want to share a sense of wonder, simplicity, and warmth. I hope to connect with others in a way that goes beyond words”.
Her necklaces and earrings are sure to delight you!

Amethyst Clusters are said to calm the mind, to deepen spiritual connection, and even to strengthen the immune system. They are often used in Feng Shui to clear negative emotions. We think these hand-selected clusters look great on a windowsill among houseplants!

Susan at Garden Anatomy is a friend to Harlequin’s staffers. Her love of gardening blended with her desire for a beautiful, functional gardening toolbelt resulted in some of the prettiest toolbelts we’ve seen. We’re glad to bring them to you at this year’s market.

Eve’s friend Sue Hagedorn is a Longmont fiber artist. She has brought us a large assortment of beautiful indigo-dyed scarves and up-cycled clothing. Many of these one-of-a-kind garments are from high-quality fashion brands.
An Anchorage, AK native, she became interested in indigo dyeing at a workshop there and was drawn to its healing and quiet contemplative properties. She has explored the traditional Japanese art of Shibori (a method of folding and tying to produce dye-resist patterns), and dyeing with a variety of natural materials on natural fiber fabrics, table linens, clothing and paper of all kinds. Sue also teaches indigo dye workshops outdoors during the warm months.

It’s the time of year when we’re itching to begin planting for the season and preparing for this year’s growth. But hold onto those shears! We know that regeneration is occurring in our soil, with microbes and overwintering insects. Delaying Spring cleanup for another few weeks will ensure a healthy, vibrant ecosystem that best supports your plants. Here are tips for you to best help this process take place, while still having an aesthetically pleasing garden. [Read More]

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]

I don’t know about you, but I’ve had to forego some of my morning rituals to make time to reap the bounty from my garden these last couple of weeks. I fully expected the temperatures in the 90s and occasional triple digits to stall the production of my tomatoes, but somehow the blossom-drop and lack of fruit-set experienced in previous very hot summers never materialized, and now I’m bringing in armloads every few days! And how about them eggplants! Swiss Chard, Collards and Kale abound, and my Tromboncino climbing Zucchini is feeding the neighborhood.
I have two new tomato varieties to add to my list of top favorites: Tidy Treats and Tasmanian Chocolate (I’m a sucker for anything with chocolate in the name or ingredients list).
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.

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.

In our experience, fall is the most successful time to establish most plants, especially when mycorrhizae are applied to the roots during planting (and we’re well stocked with several types of mycorrhizae!). 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?

This mineral-rich, vegan broth offers many of the benefits of traditional bone broth! As we slow down, herbs and plants you grow from Harlequin’s Gardens can nourish you this winter. Many thanks to Mitten Lowe at Journey to Wellness for the recipe.
