Begonia lucerna

Begonia lucerna is highly valued for its ability to grow in low light environment while providing extravagant colours. Begonia Lucerna whose full name is Begonia Corallina de Lucerna is a hybridized form of the Angel Wing Begonia. It was hybridized by Wettstein of Lucerne, Switzerland in 1892. This evergreen flowering Begonia may be less spectacular in bloom than other Begonias but has the advantage of keeping its beautiful "Angel Wing" leaves through out the year. It is one of the popular cane-stemmed Begonias. It is easy to grow and propagate. Begonia lucerna can reach the height of 6 ft or more if left unpruned. The leaves are narrow "Angel Wings", olive green with small silver spots on the top and often red-veined. The flowers are large clusters which hang from the stems.
