Wisteria frutescens 'Amethyst Falls'
Hardy zones 5-9.
15-30 ft ht. spread 2-4 ft.
Medium growth rate, but slower growing and tamer cultivar than species. Under ideal
conditions this variety can be expected to live for about 30 years.
Full sun to part shade, but only flowers when in full sun.
Does best in average to evenly moist conditions. Will not tolerate standing water. It is not
particular as to soil type or pH.
Grape like lavender-purple flowers in late spring to early summer attract native insects.
Thin whip-like stems coil up any available support and harden into a woody trunk. Needs
substantial support and should be planted at the base, where it can be trained to grow
upward. Or allow to trail off a retaining wall or slope.
As a climbing vine, it tends to be leggy near the base and should be under planted with
low-growing facer plants.
This is a high maintenance vine that will require regular care and upkeep, and should
only be pruned after flowering to avoid removing any of the current season's flowers.
It blooms on new wood, so may be thinned or shaped at almost any time.
Attracts native butterflies and insects.
Parts of this plant are known to be toxic to humans and animals, so care should be
exercised in planting it around children and pets.
