Begonia Rex 5"
Rex begonia (Begonia rex-cultorum) is a semi-tropical perennial plant normally grown as an outdoor container plant or houseplant. The forms sold commercially are carefully cultivated varieties of the B. rex species native to parts of eastern Asia. If planted in the garden (a relatively rare occurrence), rex begonia is grown as an annual in all but the warmest climates.
A Begonia Rex plant needs plenty of bright indirect light but no direct sun. Since a Begonia Rex does not bloom very often, it does well in less light than some other begonias and can even grow under fluorescent lights
Allow the top 50% of the soil to dry out before you water. Begonias like to be evenly watered but hate being over-watered. During the winter, when the plant is dormant, reduce your water.
