    How to Germinate a Wisteria Seed
    Wisteria (Wisteria sinensis) enthralls many gardeners with its fragrant, purplish flower clusters, which drape along the stout, woody stems during the summer months. Most gardeners who decide to propagate wisteria at home do so from cuttings, but it is also possible to germinate wisteria seeds if you soak them in warm water just before sowing. However, wisteria seeds exhibit a low rate of viability and the resulting vines will take up to 20 years to fully mature and flower.
     
    Instructions
    1. Pot wisteria seeds for germination in early spring before daytime temperatures top 55 degrees Fahrenheit. Avoid starting the seeds when it is colder than 50 F since they will remain dormant.
    2. Soak the wisteria seed in a bowl full of warm, 100 F water for 24 hours before sowing it. Prepare a pot for the seed as it soaks.
    3. Fill a 4-inch pot with a mix of 2 parts potting soil, 1 part perlite and 1 part coarse sand. Pour water into the pot until the top half of the soil mixture is saturated.
    4. Sow the wisteria seed in the pot to a depth of 1 inch. Cover the soil with a thin layer of coarse sand to help keep the soil moist.
    5. Place the pot in a cold frame or ventilated greenhouse. Check the soil moisture once a week to ensure the top half does not dry out completely.
    6. Close the ventilation in the cold frame or greenhouse in midspring once temperatures rise above 65 F. Add water to the pot when the surface of the soil mixture feels dry when pressed.
    7. Watch for germination in two to three weeks. Keep the wisteria seedling in its pot for six weeks after germination, then plant it in a permanent container or bed once it grows to 5 inches in height.
