A group of begonias that produce thickened stems or rhizomes. These can
creep along the surface, grow erect, or creep under the surface. They are
a large group and need a variety of cultural environments. The following
is a general guide.
Light: Light shade and no full sun. Too little light will give
spindly growth and too much will give yellow foliage and poor plant
Temperature: A temperature of 55 to 65F.
Humidity: They prefer a moderate humidity range between 40 and 70%
Compost: Rhizomatous begonias like a well-drained compost. They
will rot if it is wet and soggy.
Feed with a balanced fertilizer as long as the plants are active.
Propagation: Will root easily from a piece of rhizome or a leaf
