Though commonly associated with culinary traditions of the Southeastern US, collards originated in Europe, along with kale, cabbage etc., and are easy to grow in cooler climates, too.
Grow collards in full sun (for fastest growth), or part shade. Give them plenty of space, 18” apart. Collards appreciate moist, fertile soil with plenty of organic matter (compost) and applications of compost tea. [Read More]

Give yourself a break by putting away your lawn mower for the month of May with the additional benefit of feeding our early bees!

Monarch butterflies previously considered Threatened, have now been classified as Endangered by the International Union for Conservation of Nature, the world’s most comprehensive scientific authority on the status of species. Two major driving factors are habitat loss (and thus, food loss), and climate change.
We are here for you! You’re in the high desert/steppe now, with short growing seasons, sudden temperature changes, unpredictable precipitation, low humidity, drying winds, alkaline soils that are low in organic matter and nitrogen, hot summers and cold winters. Despite these challenges, gardens can thrive here, and be productive, rewarding and beautiful!
Opening Day will be here in just a few minutes (or it seems to our busy-bee staff!) and our doors will re-open this Thursday, March 3rd at 9 AM. We hope to see you then!

The bad news is that last week’s small delivery of tomato starts froze when the wind blew open the back door of our greenhouse in the middle of the night.

What a glorious spring! Having been blessed with generous snow and rain, the land is bursting with energy, greener than green, and flowering in kaleidoscopic exuberance! Migratory birds have been arriving or passing though our region this month, offering sightings of avian treasures like Lazuli Buntings and Western Tanagers, not to mention the hummingbirds. We do live in a wondrous world!
Our Annual May Day Festivities and Spring Sale begin May 4th!

With the Thanksgiving holiday approaching, we’d like to take this opportunity to express our gratitude for another great year, our 30th!, at Harlequin’s Gardens.
So they can support us!
Dear Friends and Fellow Gardeners,
Our hearts go out to the many people who suffered devastating losses in the Marshall wildfire. It may be possible to rebuild homes, but their contents may be irreplaceable and the sudden disruption to lives will present great challenges. Communities will also need to be rebuilt, and we are hoping the larger community will continue to step up to offer long-term support to all those in need. It takes a village! 
Historically February is one of Colorado’s snowiest months, and finally we’re beginning to see evidence of that this year! Additionally, the forecast indicates more to come. It remains to be seen how some of our marginally hardy garden plants have suffered from the below zero temperatures.

This year the Winter Solstice will fall on Tuesday, December 21st. This astronomical event is the time of the year when the Earth’s north pole is tilted farthest from the sun, so that night is the longest and daylight is the shortest (in the northern hemisphere). This day has long been celebrated because it signals the lengthening of the days until Summer Solstice on June 21. Even though there is a lot of winter left, there will be more day light. It is the promise of Spring to come.

Our customer and friend Diane Patterson makes these wonderful ornaments, called Temari, which date back to ancient Japan, where Temari was originally a handcraft of upper class women. Intricate designs were embroidered on handmade balls using silk threads from kimonos. The balls were used as toys.
Erin Huybrechts Davis says she has been a painter for as long as she can remember. She grew up on the east coast, has her degree in painting and printmaking, and a masters degree in education. She now lives here in Longmont, CO, where she is a freelance illustrator and teaches art to young people.


We are appreciative of the community support at our Holiday Market opening weekend! With the perfect autumnal weather, more people than ever were able to enjoy our local musicians, Sandra Wong & Jon Sousa’s world music, and Margot Krimmel’s traditional and original harp pieces.




Our friend, Jason Kapella, an oil painter based in Hygiene, Colorado, channels over thirty years of exploration in the American West into his vibrant canvases. From footpaths to mountain boards, bikes, and fishing rods, his journey transformed into a serious dedication to painting in 2012.
Joseph Sikora was trained in a small woodcarving studio in Bavaria, Germany. He worked under the guidance of a master carver for 8 years. In 1991, he returned to the USA and opened his own business in Colorado. Joseph is active in the fields of fine art sculpture, religious art, custom furniture and architectural carving. Some of his latest projects have been to create “Old World castles & cottages” using recovered Cottonwood bark from trees in Boulder County. Joseph is passing on his knowledge through teaching carving in Boulder, Lakewood, Louisville and Westminster. He is a member of the Louisville Art Association, Colorado Carvers Club, the National Association of Woodcarvers and a founding member of the East Boulder County Artists.
Years ago, Julie and Eve were classmates at the Boulder Potters Guild. Julie’s passion for clay subsequently led her to create her own home studio in Longmont, where she applies her hand-building skills and sense of whimsy to making delightful decorative and functional pieces.

Mason Bee populations plummeted throughout Boulder County due to harsh spring weather, so it’s especially important to coddle them this winter! Mason bees normally nest in holes in tree trunks, which offer stable temperature, moisture, and protection from predators. To provide extra assistance, bring your Mason and other native bee tubes/cocoons into a sheltered place with ambient (outdoor) temperatures, but with less fluctuation, like a garage or refrigerator. Cocooned bees are now adult and safe to handle in their cocoons. If you used liners or reeds, take them out of the guard tubes and shelters and store them in the fridge. Ideally, unwrap the liners/reeds and just overwinter the mason bee cocoons. Place them in a Humidi-bee chamber (in stock), and keep the lower pad moist.
