- Description
-
Evergreen wisteria is a native of China, NE Vietnam, and Taiwan. Like true wisteria it is a woody climber with racemes of pea like flowers. However, as you can tell from its scientific name, Callerya reticulata, it is not a wisteria although both plants are part of the Legume (bean) family and the growth habit, leaves, flowers and fruit are similar. The genus name is in honor of of Joseph Callery, a French 19th century French missionary who traveled and collected botanical specimens in China. The species name 'reticulata' means 'netted' and refers to the pattern of the veining on the leaves.
This plant is hardy in regions 8-10 so it may be tender in parts of North Carolina. If you have an area sheltered from the winter weather you could try training it up a wall. This plant likes a sunny spot with fertile, well drained, loamy soil with a pH between 5.6 – 7.5. It can grow up to 15 ft tall and 6 ft wide so train it up an arbor, trellis or pergola to provide shade on a summer's day. Surprisingly, it can also be grown in a container. The flowers are scented so place the container where you can enjoy the fragrance. This plant requires moderate watering so don't let the container dry out and feed it with a water soluble fertilizer every 2 weeks. If you want more of them just plant a few seeds or take stem cuttings.
The fragrant flowers make this plant ideal for a fragrant garden but it would also be at home in an aromatherapy garden or a naturalistic landscape.
One the great things about his plant is that it has been used in Chinese folk medicine for many years. It is known as 'Chicken Blood Stem' due to the reddish resin contained within the stems. Traditionally it is used to treat blood, menstrual, and circulation related disorders. As it also has anti-inflammatory properties, it is used to relieve auto-immune diseases like rheumatoid arthritis.
