If you don't believe me, head over to the Horticourt and check out the agaves and haworthias. You'll also find books on them in the AIA bookstore, near the entrance to the show. And there are lots for sale in the Marketplace. In short, succulents are huge.
And that is no accident. They're low-maintenance, require little water, and pound for pound, they're about the coolest looking plant going. They're perfect for dish gardens, window sills, containers and terrariums. I use them for ground cover. It's not about the flowers for me, although are beautifu. It's the chubby leaves and weirdly beautiful geometric shapes and exquisite color combinations, including shades of blue.
Look them up: aeonium, agave, aloe, cactus, echeveria, euphorbia, haworthia, sedum, sempervivum .. and you can find them in any garden center now. They are particularly attractive to younger gardeners, a demographic everyone wants to capture.
For reading material, you can't beat Debra Lee Baldwin, who is about to release her third book about succulents. First two were Succulent Container Gardens and Designing with Succulents. Succulents Simplified: Designing and Crafting with 100 Easy-Care Varieties is coming out in May. (Timber Press)
