Introduced to Western gardens in 1816, this native of China is a rampant, hardy, deciduous woody vine that blooms showily in late spring with long hanging clusters of lightly fragrant pea-like flowers in lilac-purple or white, followed by hanging velvety green pods. The flowers open in unison, providing a spectacular display. The bright green pinnate leaves usually have 11 leaflets. This massive twiner can literally cover acres if allowed to romp freely. There are many cultivars, including white-flowered 'Alba' and the floriferous 'Prolific.'
This wisteria, like others, grows and blooms best in full sun and well-drained soil, and sometimes takes several years to flower. Soil that is too rich in nitrogen may promote leafage at the expense of flowers. Large and vigorous, Chinese wisteria needs a sturdy structure for support and pruning to keep it in bounds. It can be trained as a small tree by staking a shoot upright, removing side shoots and restraining the top shoots by pruning for several years until the stem is self-supporting. It is listed as invasive in several areas including the eastern United States. (info source: Learn2Grow.com)

| Germination | 1. Place the wisteria seeds on a flat surface. Scratch the outside seed coat two or three times on each side using a sharp knife. Do not cut deeply into the seed. 2. Fill a bowl with 1-cup warm water. Drop the seeds into the water. Push on any floating seeds gently with your finger to submerge them. Leave the seeds to soak for 24 hours. 3. Place 4-inch plastic pots on a flat work surface, setting out one pot for every seed you intend to plant. Pour seedling potting mix in each pot, leaving a 1/2 to 3/4 inch of space between the soil level and the top of the pot. Tamp down the potting soil firmly in each pot. 4. Fill each pot with water two or three times to moisten the soil. Allow any excess water to drain from the holes in the pots' bottom. 5. Pour the seeds and water into a strainer to discard the water. Place one seed on the soil in the center of each pot. Cover each seed with a 1/4-inch layer of potting mix. Moisten the top layer of soil in each pot using a misting nozzle connected to the garden hose or a spray bottle. 6. Cover a pot with a square of plastic wrap. Pull the sides of the plastic wrap down over the sides of the pot. Place a rubber band around each pot to hold the plastic wrap's edges in place. Repeat this process with each pot. 7. Place the pots in an area that receives bright, indirect sunlight. Choose a room with constant temperatures between 70 to 75 degrees. Position the pots away from heating or cooling vent, fireplaces, heaters or air conditioners. 8. Check the pots every two or three days for signs of moisture loss. Remove the plastic wrap when the top layer of soil looks dry. Mist the soil with the misting nozzle or spray bottle. Replace the plastic wrap. Keep the soil evenly moist, but never soggy. 9. Remove the plastic wrap from its pot when a seedling appears above the soil level. Water the soil when the top 1/2-to-1-inch begins to dry. 10. Transplant the seedlings into 6-inch plastic pots full of potting soil, one plant per pot, when they develop two to three sets of leaves. Fertilize the seedlings weekly with a 10-10-10 nitrogen, phosphorous, potassium fertilizer at a rate of 1 teaspoon per gallon of water. Water seedlings when the top 1 to 2 inches of soil becomes dry. 11. Place the wisteria starts outdoors in direct sunlight during the morning hours only. Increase the amount of outdoor time and direct sunlight exposure each week. Transplant the wisteria starts outdoors once they are 12 inches tall and used to being outside all day and night.
