Nursery contributed plant descriptions

A semi succulent shrub from Madagascar, hardy to 30 degrees. Outside it likes semi shade, inside it requires full to part sun. A great potted plant, it blooms all summer with pairs of bright red flowers with yellow centers. No thorns. Hummingbirds love it.
A thornless Crown of Thorns that produces a Non-Stop show of bright glowing red, 1-1/2" wide crown of thorn blooms throughout the year atop the thornless stems and glossy green foliage. One of our favorites! Can be trained into a beautiful and exotic small tree standard.
