Post by Pam Glogowski
This blog post will follow the theme of over-wintering favorite plants that I started in my January 17, 2017 post about plectranthus. Like most gardeners, I’ve collected some wonderful tender specimen plants over the years, and because I can’t bear to part with them I bring them in the house for the winter. My family moved back to Janesville from the southern U.S. in July 2015, and we were lucky to find a house with a beautiful greenhouse window in the exposed basement. This window provides great light for the smallest plants I bring in, including two of the four begonias highlighted in this post.
Begonia ‘Jurassic Watermelon’
The large genus Begonia consists of more than 1500 different species and hundreds of hybrids. According to Brad Thompson of the American Begonia Society there are eight types of begonias: canes, shrubs, rhizomatous, semperflorens, tuberous, rexes, trailing/scandent, and thick-stemmed. The small plant pictured above is a rex begonia that grows well in containers and prefers rich, moist, well-drained soil. The rexes are grown for their spectacular foliage and have insignificant blooms.
Begonia ‘Tiger Kitten’
‘Tiger Kitten’ is a rhizomatous begonia, a group of plants that doesn’t get very tall but can get quite wide because they grow from rhizomes that creep along the ground. I keep this plant in a container year-round and you can see that it is starting to make new leaves as our days grow longer. Spring is surely on its way!
This ‘Sophia’ is about 30″ tall. It is a cane begonia that gets long and leggy in appearance. Most all begonias propagate easily from stem cuttings, so I often cut the longest canes of this plant, place them in a vase of water, and wait for them to grow roots before planting them. The leafless cane that is left behind on the mother plant will grow new leaves from any remaining nodes (the swollen areas at regular intervals on the cane). These are the plants commonly called “Angel Wing” begonias. Some cane begonias can grow up to almost 12 feet high in frost-free areas where they remain outside, but can be kept smaller and used as houseplants in cooler climates like ours here in Wisconsin.
This photo shows the three plants highlighted in this post with my fourth begonia ‘Crystal White’. I hope that you have some begonias – they bring color and cheer to our winter days, and thrive beautifully in the house. They can be moved outside in the summer after all danger of frost has passed. Like most begonias they prefer shady areas like covered or screened porches.
