Do you have an area of your yard you’re not sure how to use—a slope, a dry sunny spot, or a shady corner? The magic of rock gardening might be the perfect solution.
Rocks and stones can transform challenging spaces into beautiful, naturalistic gardens. A carefully placed stone provides year-round structure, creates protective microclimates from Colorado’s wind, and offers cooling shade for plants. Crevice gardens encourage roots to grow deep and for drought tolerant plants to thrive. With rocks, the possibilities are nearly endless.
The Rocky Mountain Chapter of the North American Rock Garden Society invites you to enjoy three inspiring presentations by renowned experts, along with the RMC Spring Plant Sale at Tagawa Gardens. Visit the Events Page for details on the sale : RMC Saturday Spring Plant Sale
Saturday April 11th Presentations at Tagawa Gardens
- Marcia Tatroe – Rock Gardens Rock! Have you fallen in love with those cute little treasures in the rock garden section but aren’t quite sure what to do with them? A rock garden is the answer. You can fit a large number of plants into a small spot making rock gardens ideal where space is limited. And because rock garden plants are tough and weather resilient, no garden is better suited to Colorado’s capricious climate. This class covers the basics of building a rock garden including construction, soil and rock options, rock placement and plant selection.
- Panayoti Kelaidis – A Rock Garden in your Garden. We all moved to Colorado because of the beautiful mountains, wonderful canyons and prairies, but we often replace these with yards that could be in New Jersey or Oregon. This talk will feature plants that are suitable for this climate in rock gardens.
- Kelly Grummons – Winter Hardy Cacti for Front Range Gardens. Learn about cold-hardy cacti that thrive in our region, featuring plants Kelly has collected, propagated, and hybridized to add year-round interest and beauty to gardens and rock gardens alike
Check back later for the times of the Saturday presentations at Tagawa Gardens.
