Begonia x semperflorens-cultorum

Begonia x semperfloren-cultorum consists of a group of cultivars of hybrid origins, most likely derived originally from Begonia cucullata var Hookeri and Begonia schmidtiana. There are many cultivars and strains known. Many of the strains are variable in size and compactness of the plant, foliage color, size, color and degree of doubling of the flowers. They are the most common Begonia used in the plant industry today. Plants should be treated as annuals if grown outside in USDA zone 7.

Blooming Time: The plants flower non-stop all season long.

Culture: Begonia x semperflorens-cultorum do well in full sun to full shade with a moist well-drained soil mix. In the greenhouse, we use a soil mixture consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. The soil is kept moist for optimal growth and flowering. Plants are fertilized every other week with a balanced fertilizer. During the winter months, water is somewhat restricted, but the plants are never allowed to dry for long. Fertilizer is applied monthly during this resting period at ½ the normal rate. Also during the resting period, we cut the plants back hard and propagate them for spring.

Propagation: Begonia x semperflorens-cultorum are propagated from leaf and stem cutting, and with the newer cultivars from seed.

Begonia x semperflorens-cultorum was featured as Plant of the Week September 17-23, 2004.
