  HARLEQUIN’S GARDENS CLASSES AND EVENTS FOR 2018

Our teachers have spent years honing their skills in Colorado and will help guide you to success. We are charging $15 (unless otherwise stated) for our classes to support our speakers and Harlequin’s educational direction. It is best to pre-register for these classes both in case they fill up, or too few people register and we have to cancel. Pre-payment assures your place in the class. (We can only accept cash and checks for class fees.) You can register at the nursery, by mail, or by calling 303-939-9403. 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.
