Begonia x hiemalis are more commonly known as winter begonias or Rieger begonias. They were developed by Otto Rieger and are are a hybrid between wax begonias and tuberous begonias.
They are ideal winter-flowering indoor plants, as they prefer cool temperatures-around 70 degrees in the day and 60-65 at night. They do best in bright indirect light-an east window is best.
Grow them in well-drained soil and feed with half-strength fertilize while they are in bloom. Remove spent flowers to stimulate new bloom. Water the soil when it’s dry about 1/2″ down. Don’t overwater, and water the soil, not the leaves. These are not humidity lovers-another reason why they do well indoors!
These cheerful flowers are a great way to brighten up your home in the winter!
