Wisteria is a fast-growing, deciduous vine that, according to the National Gardening Association, can grow 10 feet or more in one year. They are noted for their fragrant flower, which resembles clusters of grapes.
Wisteria is very versatile and can be grown as shrubs, vines, or even trees. Wisteria can grow to achieve heights of 20 to 30 feet with flowers widely in color.
How to Grow Wisteria Seeds
It’s best to wait until fall to gather the seed pods you want to work with. Once the mature plant has lost its leaves, it’s time to choose your pods. Pick the pods before they’ve opened and place them in a warm, dry spot. You’ll need to allow them to dry completely until they become quite brittle. When you’re sure they’re totally dry, twist them to release the seeds.
If you want to wait until spring to start your seeds, just put them in a sealed container. When you’re ready to get the seeds started, soak them overnight in warm water. Fill sterile starter pots with well-draining sterile soil, allowing one pot for every one or two seeds. Soak the soil until it drains thoroughly from the bottom of the pots. Plant the seeds one inch (2.5 cm.) or less deep and place the pots where they will be at at least 65 degrees F. (18 C.).
Water the little pots as soon as the surface of the soil starts to dry. You can cover the pots with plastic until sprouts appear. Germination can take from one to two months.
