From your previous visits in the last eleven years, many of you know that our Holiday Gift Market is the most rewarding, enjoyable place to shop for your holiday gifts, relaxed and far from the madding crowd! When the Covid pandemic began, we realized that the only way we could keep our customers (and staff) safe and happy while shopping our Holiday Gift Market was to move it up to October!

A Hint of Fall Specials
Summer is waning. Nights are cooler and we’re even closing some windows again. Lots of plants are producing seeds. The most comfortable planting season is here, and so are thousands of plants. And to sweeten the season even more, here come our Fall Sales! Next week you will receive our Fall Sale E-Newsletter, with complete information about our special Member’s Sale at the end of August, and our progressive Fall Sale for everyone! In the meantime, we have some pop-up sales appropriate to the season – see below for the details.
Versatile Vines for Colorado Gardens

Sweet Autumn Clematis
Vines are very valuable for their versatility, variety and vigor, especially in the vertical plane. Sorry, I couldn’t resist. Many of us live in urban environments full of walls and fences, and closely packed homes with narrow side-yards. Those of us in townhomes, condos or apartments have only tiny patio gardens or balconies offering little opportunity for greening our outdoor spaces. Or, we live in new developments built on open farmland without mature trees and shrubs for shade or screening. In all of these situations, vines can quickly provide short-term or long-term solutions to provide privacy or shade, maximize our connection to the earth, block unpleasant views, cover ugly surfaces, or add a vertical dimension to the garden. And some vines can also work as groundcovers in tough situations, like under evergreen trees.
Dead or Alive?

Lace Bark Pine

As we enter June, most of our trees and shrubs have leafed out, but not all. Some have leaves only three quarters of the way up, and many broad-leafed evergreens are mostly brown. Should we cut them back or replace them? Let’s not, just yet.
May Day and Mother’s Day
With a clear signal from Mother Nature in the form of a lovely spring day, Harlequin’s gardeners came out to play and shop last weekend, taking in the delightful spring ritual dancing of our friends, the Maroon Bells Morris Dancers, and taking advantage of our May Day sales. We hope you’ll come out this weekend too, to enjoy our wonderful live music!
Our plant sales continue through Sunday May 7th, with a Deep Discount section still brimming with excellent perennials and various other plants, as well as 25% off our beautiful Cool-Season Vegetable starts. (Mountain gardeners – this is your moment!) And for Members, our offer of $5 off a full-price plant purchase of $50 or more still applies through Sunday. HERE are the sale and event details.[Read More]
April 29 – May 7: 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 Week!
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,
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]
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.
HARLEQUIN’S GARDENS 2023 SPRING NEWSLETTER
Dear Friends and Fellow Gardeners,
Welcome to Spring, to Harlequin’s Gardens and to another opportunity to mix your molecules with soil biology and partner with nature. Those of us who garden reap tremendous benefits, no matter how experienced or inexperienced we are. It’s no wonder gardeners are healthier and more cheerful.
The 21st Century is an exciting time to be gardening because we are outgrowing the petroleum mentality of solving food and landscaping problems with chemicals and poisons. We are learning how to support Life with biological solutions. It is said that we are now in the Age of Biology because our biggest problems are biological and our most successful solutions are biological. And the United Nations has designated 2021-2030 the “Decade of Ecosystem Restoration.” Some people aren’t paying attention, but a lot of us have already assumed the job of helping to heal our environment, our people and our planet. Every act of kindness, of support, of nurturing and sharing, helps to uplift some pollinator, some frog, some bird, some microbe, some child, some hungry person, or somebody just like you.
Hold off on Spring Cleanup and Build a Strong Backyard Ecosystem

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]
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.
June is Colorado Pollinator Month!
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]

Winter Solstice Greetings

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]

2023 Fall Sale Information & Newsletter!
Dear Friends and Fellow Gardeners,
Welcome to Autumn and to Harlequin’s Gardens 2023 Fall Plant Sale!
Gardeners can’t be faint-hearted. No matter how much we know, we have to be prepared for the unpredictable. Last winter’s three waves of below zero weather caused some woody plants to die back that have been hardy for decades. Then we were blessed with rain. Denver’s 6” of rain in June broke a record. At the same time, we are having the “hailiest” year in Colorado history. And while other regions have suffered extreme heat, our area has had a record number of days under 90 degrees. Many of our gardens have never looked better.[Read More]
