The species crassifolia is worthy of notice. Because of its succulent, fleshy leaves it is one of our very best basket plants. It withstands the heat and drying-out process which our hanging baskets undergo better than almost any of the plants we use for that purpose.
It is most easily increased by cuttings at any time of the year. A rather light, sandy soil suits it best, and when its pendent growth is any length you should find some place for it on a shelf. Don't give it a cold, damp place in the greenhouse, but keep it warm and growing, and you can multiply it indefinitely, as the small pieces of the stem will root anywhere.
