Amethyst Falls Wisteria




North America’s Well-Behaved Wisteria

Hardy Wisteria All the Way to Zone 5
Amethyst Falls Wysteria is a fast growing vine that produces full purple flowers up to 12 inches long.  Zones 5-9  can enjoy a graceful show of shimmering beauty that is otherwise typically reserved for the sunny south. This is a sterile plant, so it won’t choke out your other trees and take over your yard like many Chinese varieties of wisteria. Your tree will blossom each spring with cascading flowers and will lightly repeat throughout summer. While the blooms steal the show, the green foliage is impressive in its own right. New leaves are so shiny they look lacquered as the sun plays over them.

Easy to Grow and Maintain
The Amethyst Falls Wisteria is easy to grow and adapts well to a wide range of soils.  Once established, it’s drought tolerant.  There are no known issues regarding insects or pests, and it’s deer resistant as well.

There are so many options to grow the beautiful Amethyst Falls Wisteria. It flourishes quickly at the onset of spring, elegantly wrapping around fences and trellises. If you’re one of those growers who are eager to see results as soon as temperatures warm up, you’ll love how swiftly this vine swings into action. Allow the vine to climb across your pergola.  You’ll reap the benefits of shade as you admire the lightly scented lavender flowers that flow above. This variety will easily grow in a container.  Stake it in order for it to grow upright in tree-form.

Planting & Care

The Amethyst Falls Wisteria (Wisteria frutescens ‘Amethyst Falls’) is a beautiful blooming vine that is great for all of the joys of wisteria but without the fears of it overtaking your property. This particular type of wisteria is commonly planted in USDA growing zones 5-9. It is drought tolerant, widely adaptable to many soil types and will mature to a height of 20-30 feet and a width of 5-8 feet. The Amethyst Falls prefers full to partial sun and to be spaced roughly 10-15 feet apart as to not inhibit their moderate growth rate. Their flowers can reach lengths of up to 12 inches long!

Choosing a location: The ideal spot for planting wisteria should be a sunny area with fertile, moist, well draining soil. Wisteria thrives in almost any soil type as long as it is well draining and receives at least 6 hours of direct sunlight.


Planting directions: Anytime from spring until fall is the ideal time for planting your wisteria.

1) Dig a hole that is three times as wide as the root ball and just as deep (if planting more than one, space the plants 10-15 feet apart).
2) Prior to planting your wisteria add plenty of compost or well-rotted manure to your soil to improve drainage and soil fertility.
3) When placing your wisteria in the hole, try to spread the roots out a bit by gently combing them with your fingers.
4) Gently hold the plant while making sure it’s vertical in the hole and back fill the hole with your other hand, working the soil around the roots to avoid air pockets. Then gently firm the soil down with both hands, but don’t pack the soil too tight as it could harm the root system.
5) Make a rim of soil around the edge of the planting hole. This basin-like ring will catch and hold water channeling it directly down to the root system.
6) Give the wisteria’s planting site a thorough soaking of water and cover with mulch to retain moisture.

Watering: During your first year the wisteria will benefit from regular watering while the roots become established. An inch of rainfall per week is recommended which equals out to about 4 gallons of water weekly. Water your wisteria in the morning or evening on hot, summer days to allow the plant to soak up the water before it evaporates. A slow trickling from the hose works best so the soil can absorb water without run off. Once fully established the natural rainfall in your area should be sufficient for your wisteria unless in times of drought, then you will need to water once every two weeks.

Fertilizing: Your wisteria will require little fertilizing if any at all, excessive fertilizing will inhibit the blooming. If you have poor or sandy soil then consider using a small amount of fertilizer like formula 5-10-10 or 5-10-5. Feed your wisteria about 3/4 cup per square yard each year during the spring.

Pruning: Wisteria (unlike many plants) needs to be pruned twice a year, typically once in late winter and again in mid-summer. Winter pruning is to prepare the flowering spurs for the upcoming season. Summer pruning keeps the long, whip-like shoots under control encouraging them to become flowering spurs. Don’t concern yourself too much if you make a mistake in the pruning your first time around. Wisteria is a forgiving, vigorous grower and the next season will give you another chance.
