The tuberous type of begonia is also very popular around the
world as a bedding plant and also as a greenhouse plant. In some countries
such as England it is the main type grown. The tuberous types are grown
for their flowers although there are a few varieties and species which
have interesting leaves and growth.
The flower size can range from small,
1/2 inch flowers, to the large exhibition types that can have flowers the
size of dinner plates. The flowers range in type from singles to full
doubles and come in every color except shades of blue. There are even
flowers with different color edges and some are scented. The plant types
range from trailers that are grown in hanging baskets with pendulous
flowers to sturdy upright plants. The tuberous types grow from tubers and
go dormant during short days during the fall and winter. They are
restarted in the spring.
Another related type is the semi-tuberous which
doesn't have a tuber but which have form a caudex, or swelling, at the
base of the stem. Most semi-tuberous have small leaves and small white
flowers, but at least a couple are pink. They make almost a natural bonsai
with their swollen base and small stems and leaves.
