Selaginella : Greenhouse Plants
W – warm, minimum of 13°C (55°F)
The most commonly grown is Selaginella kraussiana from South Africa which is bright green and covers the ground creeping like a large moss and rooting from its stems as it goes. It certainly has its place amongst greenhouse displays especially when planted in shallow pans and placed at the edge of the staging. S. k. ‘Brownii’ is a dwarf form from the Azores which makes small domed pots full of bright foliage that with a little imagination looks like crinkled. There are also golden and variegated forms. There are many other species which all require reasonable warmth and humidity to do well. If you have trouble growing them successfully then try planting them in an old fish tank with peaty in the bottom over some drainage material. Occasionally S. lepidophylla, the Resurrection Plant, Rose of Jericho or Desert Rose from Texas and from Arizona to El Salvador, are offered for sale as dried up brown balls. These miraculously green up and begin growing when they are placed in water making them a great favourite with children. However, I would recommend that they be potted after a week or two in water. They are often listed at the back of seed or bulb catalogues. Air Plant firms are also likely to stock them.
