Rhizomatous begonias are the largest group in cultivation. There are well over 700 known species and hundreds of cultivars both named and un-named. As the name suggests, these begonias have a rhizome that is essentially a thickened stem.
The leaves of rhizomes are very diverse in both size and shape and mostly come from Mexico, Central and South America and more recently, Asia. These plants bloom once a year, usually in late winter or early spring, producing a gorgeous flower cluster of very graceful habit. Whether in flower or not they have a spectacular display of foliage.
