Aptenia cordifolia aka ice plant or baby rose plant is a native to the southern Africa geographic region. Aptenia is a beautiful, drought tolerant tropical green roof plant and does well in some Florida environments however the green roof designer should be aware that high humidity loving fungus or below freezing temperatures may very quickly decimate an Aptenia green roof planting. Despite these issues, Aptenia is a lovely non-native horticultural specimen that will turn heads. I would use this drought tolerant plant sparingly on tropical green roofs and only in areas needing significant color splash. When used appropriately she offers significant eye appeal!
