Ruby Moon hyacinth bean: let this vine twine
When flowering vines are mentioned, many gardeners first think of Clematis. Climbing roses may enter the picture. It can take many years for either of these to achieve their full glory, but what if you could have a flowering vine that made a huge impact the first year?
Hyacinth bean in its brilliant purple cultivar ‘Ruby Moon’ is a vigorous vining cousin to beans with dark purple stained foliage attractive in its own right. The generous clusters of blue and amethyst flowers resemble a delicate wisteria, only these are produced abundantly from midsummer to the frosty days of autumn. By August expect this to be a focal point in your garden: hundreds of flowers produced together with huge flat purple bean pods and colorful foliage into the bargain.
This vine has become a focal point wherever planted at Denver Botanic Gardens: you too will soon find it to be an essential addition to a wall, fence in your garden or mounded upon itself as a perennial in the border.
