It’s Pollinator Month!

Our recent weather pattern of a sunny morning and early afternoon followed by afternoon rain showers seems to be a nice return to the weather patterns we used to have in this area.  This provides a welcome environment for gardening and planting new plants.  Our herb section is looking especially bounteous as is our collection of columbine plants and clematis vines.  We hope that you stop by to see our newest offerings of neonic-free, pollinator friendly, Colorado-adapted plants!

Our pollinator friendly plants are particularly important since June is Pollinator Month in Boulder, and June 17-23 is National Pollinator Week.  Harlequin’s Gardens is here to help you celebrate in a variety of ways! In Kristina Williams’ June Bee Buzz article below, she outlines the many ways you can support our local pollinators.  Kristina is a professional entomologist, president the Boulder Beekeepers Association, a beekeeper for 35 years, and Director of Harlequin’s Gardens’ Bee-keeping supply shop. She is available to help people with beekeeping questions and beekeeping equipment, and is teaching several Bee Classes, outlined below..

We have a not-to-be-missed class this weekend – Zach Hedstrom’s ‘Mushroom Cultivation and Identification’ class!  This is a unique opportunity for you to learn in a hands-on environment about local wild mushrooms: how to identify (participants will receive a mushroom identification packet for local mushrooms), spore plugs, and knowledge on how to grow them – a bargain for the $75 class cost!  This full day (Saturday, June 8 from 10 AM to 3 PM) class will be led by noted mycology expert, Zach Hedstrom.  We’re so fortunate to have his expertise for an entire day!  Last year Eve attended the class and said that everyone had a great time and learned so much; additionally other attendees have reported fantastic results growing their own mushrooms! Please call soon to reserve your spot as we have a 12 person maximum.   

On Sunday at 1:00, Mikl will teach you how to redirect your table scraps and garden clippings into food for the soil – a process know as composting.  In this “Successful Home Composting” class Mikl will show you how to let nature do the work for you! 

Further class details are listed below and as always, please call to register:  303-939-9403. 


Our selection of tomatoes is very abundant as is our winter squashes and melons.  Soon we will have more cucumber and zucchini starts ready for you.  Below are our current in-stock selections of tomatoes, peppers and eggplants.  





The month of June is Pollinator Month in Boulder, and June 17-23 is National Pollinator Week.  Harlequin’s Gardens is here to help you celebrate in a variety of ways!


The best way to support pollinators is to provide safe forage and habitat.  First, our plants are all neonicotinoid-free. Neonicotinoids are systemic insecticides that circulate through the entire plant, including nectar and pollen, which are collected by bees for food.  Bees, with their fuzzy bodies and need for pollen for their baby food are the best pollinators.

Second, our plants are adapted to our local environment. This means that they’re ‘happier’ here and require less chemical and water input.  We carry many plants from ground covers to trees, among them Nepeta (catmint) and Helianthus (sunflower), that will provide for pollinators in general, as well as some plants visited by bee specialists, for example Sphaeralcea (mallow) and Oenothera (evening primrose).  Even our own-root roses, selected for our climate and soils, are good for pollinators.  As a rule of thumb, if you can see the stamens, so can the bees. Ask for our pollinator plant lists to help you shop. 

Ask for our pollinator plant lists to help you shop, or prepare in advance by visiting our website “Plants for Bees and other Pollinators” and “Plants for Pollinators List”

We’ll feature pollinators in our classes too where you can learn how to support the important role of bees, birds, butterflies, bats, and beetles in pollinating our lovely flowers, native plants, fruits, and veggies. 


Saturday morning at 10 AM, our own entomologist, Kristina Williams, will show you how to recognize and attract “Beneficial Insects” to your garden. 

This is followed at 1 PM by our (Free!) and very special Habitat Hero Wildscaping 101 class.  Here Laura Somers helps you to view gardens as a bird does when seeking shelter, food and nesting opportunities.  A wealth of knowledge for a fantastic price!


Kristina returns on Sunday morning at 10 AM to share info on our most important, and perhaps underrated, pollinators: Colorado Native Bees.  She will tell you about our local species, where and how they nest, and their integral role in our ecosystem. 

Then at 1 PM, Mikl teaches us how to Manage Garden Pests Without Using Poisons – increasingly important techniques in our evolving world. Mikl has over 30 years of non-toxic gardening experience and wisdom to share!

We’re so proud to be offering these important classes and hope to see you there!  As always, pre-registration is appreciated and highly recommended for all classes with a quick call to 303-939-9403. 


This year our Bee Barn offers supplies for cultivating some of the Front Range’s 500+ species of native bees as well as the better known European honey bee.

This is the month to start making serious plans for the health of your honey bees.  Varroa mite levels will climb steeply in July, but we have the tools to monitor them and ways to knock them down before they knock your bees down. European Foulbrood has been rearing its ugly head too.  We carry easy-to-use diagnostic kits to determine whether your bees have it and will need to be seen by a vet.


Honey bees aren’t practical for everyone, but our native, mostly solitary bees did ALL of the bee-pollinating in the Americas before the introduction of honey bees from Europe in the 1600s.  They love our weather, soils and native plants. And we love them! This year we’re excited to add a selection of products to help you culture some of these gentle hole nesting bees where you live, including mason bees and leafcutter bees.  Did you know that re-using old nesting tubes or blocks drilled with holes can promote diseases and parasites? We’ve partnered with Crown Bees to bring you responsible, sustainable, clean culture methods, based on the needs of the bees.

Here’s a sample of the items we’re offering. 

Native Bee Chalet

For placing nesting tubes for the current season and an attic for placing the previous season’s bees to emerge in the current season.

Reusable cardboard mason bee tubes with disposable paper liners

For those interested in spring mason bees in particular. Pollinator Pack: Tubes in an assortment of sizes and materials provide nesting holes for a variety of our native bees.

Native Bee Guide Booklet

A brief introduction to just some of the bee species that may nest in your native bee house.

The Mason Bee Revolution book

For those who are seriously into mason bees, early season pollinators.

We are unable to take class registration by email at this time.  Most of our classes run from one-and-a-half to two hours in length, and sometimes longer for hands-on classes, or if there are a large number of questions.  See the complete listing on our website.
