Rockin’ Rose

We’ve tried for years to grow Helianthemum, the European native rock rose, which is highly prized by rock gardeners. Over the last 35 years, we’ve failed miserably…until we built our crevice garden. Here, it is currently, thriving in our soil mix of 50% Permatill (popped slate).

  1. In your crevice garden, what do you use for the other 50% of your soil composition (besides the Permatil?) I’m in Atlanta and have mixed success with growing my agave as robustly as I’d like!
    Thank you-
