“The best time to plant a tree was 20 years ago. The second best time is NOW.” While this ancient Chinese proverb still rings true, fruit trees can begin to bear at a pretty young age, bringing satisfaction much sooner than a tree planted for shade or major presence in the landscape. We carry a wide selection of fruit trees proven to thrive and produce here in Colorado and taste great, and the apples, pears, cherries and plums on the list in the link below are in stock right now so that you can plant your own for years of enjoyment. (We don’t have peaches out at the moment – ask when you come in).

Special Woody Plants

Jamesia americana – Waxflower
Mikl has assembled a collection of some of our most interesting, unusual and hard-to-find woody plants, many of which are just ready for sale now. These include some excellent native trees, shrubs and ground-covers, as well as particularly interesting and worthy non-natives that thrive in Colorado conditions. We’d like to share some descriptive profiles with you here.
Beautiful, Bountiful Biennials

Digitalis purpurea – photo courtesy First Nature
Does everyone know what a biennial plant is? It’s a plant that spends its first year of life building a substantial root system and a basal rosette of foliage. In its second year, it will have the resources to support a season of massive blooming and seeding. After having done its job, it dies away, leaving the future of its kind to the new generation of seedlings it has created.[Read More]

This week, we’re excited to bring you new tomato varieties, herbs and perennials.
Plant Select Turns 26
By Mikl Brawner
Not Just Another Pretty Face
We gardeners see a lot of branded plants in branded pots pushed with a lot of money to make a lot of money. That’s not the story with Colorado’s Plant Select program. Plant Select began as, and continues to be a plant promotion program genuinely aimed at the success of Rocky Mt. gardeners. It’s goals include saving water, supporting pollinators and encouraging a western garden aesthetic.
Legislature Forces HOA’s to Save Water on Landscaping
Around 60% of Coloradans live under a homeowner association. If you’re one of them, you know how difficult it is to get HOA approval for water-saving landscaping choices. Senate Bill 178 would allow homeowners to remove grass lawns, forcing HOAs to accept the alternative landscaping.
Blooming Without a Care

Call them what you will: when Nature chooses, She knows what She’s doing. And She doesn’t need a human audience. Nature is happy playing to the bees, wasps, butterflies, moths and beetles. We humans can learn a thing or two just by noticing and appreciating Nature’s perfect performance. And that’s just what we gardeners do.

Own-Root Roses
Did your roses take a hit from the winter cold and strong winds we just experienced? Perhaps they look as though they didn’t make it, showing brown, shriveled canes and no new growth above the ground. Or maybe there are no signs of life on the canes, but there is new growth just coming up from the ground. Either way, if your roses are growing on their own roots, you’re in luck. If they were grafted onto a rootstock, the prospects are not so good.[Read More]
May 4 – May 12: May Day Celebration and Sales!
There is something special and exciting about the arrival of May. In May, Spring weather may still be variable, but there’s nothing tentative about the progress of growth and flowering. They are unstoppable, full speed ahead!
At Harlequin’s Gardens, we love to celebrate May Day. This ancient festival from the British Isles welcomes Spring and celebrates the beauty, fertility, and abundance of the Earth. For 30 years, Harlequin’s Gardens has maintained a tradition of starting off our May Day festivities with hosting the Maroon Bells Morris Dancers, performing their lively traditional dances with bells, music, knocking sticks and waving scarves to bring forth the Earth’s fertility. The magic seems to work!
Earth Day Greetings!
It may sound trite or boastful, but truly – every day is Earth Day for us.
We are not just here to sell plants. We have a deep love and respect for plants and their roles in everything from making life on Earth possible for us humans and so many other life-forms, down to the minute details of their wondrous adaptations, behaviors and forms. We want to share all this with you,
Trees for a Changing Climate and a Resilient Urban Forest

Serviceberry
by Mikl Brawner
If you look at old photos of Colorado Front Range cities, you won’t see many trees. And if you look up native trees of Colorado, you will find a lot of mountain-growing conifers and just a few deciduous trees that grow natively along streams. And yet the quality of life for us humans depends on trees.
A Pair of Products
A Pair of Products for your Spring Lawn and Rose Care
Corn Gluten and Rose Food are two helpful products you should consider at this time of year.
Corn Gluten Meal
We normally recommend applying corn gluten for weed control a bit earlier in the year, like February and March, and NOW is a still an effective time to apply it on lawns and other spaces. Here are the details.[Read More]

Sharing a Call to Action for Local Pesticide Control

Commentary needed on Senate Bill 23-192 – the Sunset Pesticide Applicators Act
Sometimes you can make a difference. Colorado’s People and Pollinators Action Network (PPAN) is organizing a letter campaign to legislators advocating for greater local control of pesticides.[Read More]
Seed Summer Fruits and Veggies Now!
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]
Plant Recovery After a Cold, Snowy Winter
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]
“Carrots Love Tomatoes, Secrets of Companion Planting for Successful Gardening” by Louise Riotte
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!
Greener Denver 2023
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.
Pop-Up Markets for Your Bulbs and Gifts!
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.
Successful Container Gardening
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.
Self-Sowing Hardy Annuals
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]
Get Involved! 2023 Farm Bill
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!
New Year’s Greeting!
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.

Big Changes in Colorado Curbside Compost Collection
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.
Winter Solstice Greetings

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]
