About

Begonia evansiana 'Simsii' is a member of the genus Begonia in the family Begoniaceae and produces its main display in summer (June to October). It is treated in the UK as a summer-flowering begonia that is frequently used in containers or under glass when frost threatens. Give bright, indirect light, shelter from strong wind and consistently moist, free-draining compost. Male and female flowers appear separately on the same plant, so bloom can be plentiful through the season.

About the genus

Begonia is a genus of perennial flowering plants in the family Begoniaceae. The genus contains more than 2,000 different plant species, distributed primarily across tropical and subtropical regions of Africa, Asia, and Central and South America, with Africa considered the center of origin. Some species are commonly grown indoors as ornamental houseplants in cooler climates, or cultivated outside in summertime for their bright colorful flowers, which have petals but no sepals.

In the garden

Begonia evansiana 'Simsii' belongs to the large Begonia genus (family Begoniaceae), a group of plants that are widely cultivated both as houseplants and for summer display. Many begonias originate from tropical and subtropical regions, and in cooler UK climates plants are commonly used outdoors in summer and kept under cover or indoors over winter. Flowering runs from June to October, providing an extended season of interest. For cultivation, place Begonia evansiana 'Simsii' where it will receive bright, indirect light and protection from harsh sun and strong winds. Use a free-draining but moisture-retentive compost; containers with good drainage work well. Keep the compost evenly moist while the plant is actively growing and feeding during the flowering period will support continuous bloom. Avoid waterlogging around the crown. In the UK garden this begonia suits sheltered patios, conservatories, summer containers and shaded or dappled borders where it can be moved under cover before the first frosts. Regular deadheading of spent flower stems will help maintain flowering between June and October and encourage fresh shoots for the remainder of the season.
