QuestionI too have seed pods on my white wisteria for the first time. At what stage should they be picked and stored? They are currently green. I also have a greenhouse, so when could I plant them? You mentioned February to another poster. I live in the middle of Georgia, so our winters are quite mild. The greenhouse is heated in the winter but to only about 45 degrees.
AnswerHi Rhonda,
Thanx for your question. Allow the wisteria seed pods to dry and start to crack open before harvesting the bean-like seeds. Wisteria is a legume like peas and beans and germinates easily at 70F. Even in Georgia, I wouldn't start them until February and they will need a temperature of at least 70F to germinate quickly. Once germinated and after they have their first set of true leaves, you can prick out the individual plants and plant them in separate pots and put them in your cool greenhouse. Remember that from seed, it can take up to 15 years for a wisteria to bloom. Wisteria found in the nurseries are generally started from rooted cuttings and will bloom in 1-3 years depending upon the age and size of the cutting. I hope this helps.
