Tuberous Begonias Many gardeners are familiar with the tuberous begonia varieties sold for hanging baskets in the spring. Their blooms are amazing, offering incredible colors and huge flowers, some resembling the prettiest of roses.

There are varieties of tuberous begonias that grow with an upright habit and others with a trailing form.
Nonstops are a type of tuberous begonias.
As their name implies, Nonstops bloom prolifically. A healthy tuberous begonia planted in spring will begin blooming in early summer and continue until frost in fall.
