I planted two wisteria at the base of an arbor last spring. It was a beautiful plant all summer and climbed and twined on the arbor. I was looking forward to seeing it flower this year. However, the bark/stem is brown and there is no sign of even leaf buds. The plants came from a farm store garden center. The plant was in a gallon container. It is called a Wisteria macrostachya "Aunt Dee". It is labled for Zones 4-8, and I live in Zone 5. I did not do any pruning at all. Is my wisteria still alive? Will it bloom this year? Is it late to break dormancy?
