- Description
-
This annual and summer bulb, that has showy leaves and flowers, can be planted outdoors in mild climates. Its season is from summer to fall. It needs AM sun to 50% shade. Space 9-12 in. (22-30 cm) apart. The depth should be that you cover the plant 2 in. (5 cm). Technically, Begonia spp. is an organ called an enlarged hypocotyl and it has hardiness of Tender III- injured below 25 degrees F (2 degrees C).
'Rex begonias' are one of the most stunning, colorful houseplants. The blooms on 'Rex begonias' are not very showy, so they are often pinched off to encourage leaf growth. This plant needs bright indirect light year-round and humid conditions (though direct misting of the foliage encourages powdery mildew). They need consistent water but do not tolerate overwatering. They can tolerate less light than other begonias and will do well under fluorescents. It propagates easily by division through its knobby rhizomatous roots.
The flowers are citrus flavored with a slightly bitter aftertaste. They can be eaten raw, or cooked in sauces.
