With their bold, multicolored leaves, theseare probably the most strikingof all foliage begonias. Whilemany named varieties aregrown by collectors, easier-to-find unnamed seedling plantsare almost as decorative.
The leaves grow from a rhizome; see “Rhizomatous begonias” for care. In addition, rex begonias need high humidity (at least 50 percent)to do their best. Provide itby misting with a spray bottle,placing pots on wet pebbles ina tray, or keeping plants in agreenhouse. When rhizomegrows too far past edge of potfor your taste, either repot intoslightly larger container or cutoff rhizome end inside potedge. Old rhizome will branchand grow new leaves. Make rhizome cuttings of the piece you remove and root in mixture of half peat moss, half perlite.
