Rex Begonia & Begonia Rex Hybrids
Big, bold, multicolored foliage makes this a striking plant. Leaves can be 6-12 inches or more across. The plants bear clusters of 1/2" pink flowers. The flowers are attractive, but need to be removed as they age so as to keep the plant vigorously growing. These plants perform well indoors as houseplants; outdoors under partial shade, and in the greenhouse. They are grown mainly for their outstanding decorative foliage.
LIGHT: Rex Begonias need plenty of bright, indirect light. Avoid hot summer sun. Indoors, a bright east window is ideal as is a semi-shady south or west window.
TEMPERATURE: Winter temperatures of 64° and summer temps around 74° are ideal. Do NOT set plants close to a heat source.
WATER / HUMIDITY: Maintain at least 50% humidity. Water and feed regularly from late spring through early fall when plant is in full growth. Keep soil evenly moist, but never soggy. Water more sparingly and withhold food during winter.
Pot in a rich, fast draining soil. Feed weekly with a balanced fertilizer according to label directions.
Rex Begonias are sometimes available in 3" or 4" pots and occasionally in 6" or 8" hanging baskets.
