Indigofera himalayensis are native to the Himalayan ranges in northern India. Indigofera himalayensis Silk Road was introduced by Hilliers in 2006, however there is some doubt as to its exact origins as it is claimed this cultivar arose from a chance seedling from seed collected in China, however this species does not occur in China. Silk Road is now one of the most commonly planted of this beautiful deciduous shrub, renown for its long flowering period, from late spring to late summer, when the slightly arching branches are laden with short, clusters of small, pea like, pinkish purple flowers. The foliage is also very attractive being made up of small, divided, mid green leaves. Easy to grow in a full sun location in all but heavy soils. it is particularly tolerant of dry soil. In very harsh winters it can suffer some damage but it always grows back in spring! Plant in a free draining border or grow in a pot or other container. When growing in a pot or other container, use a good John Innes No.2 compost to which 20% by volume of horticultural grit has been added to improve drainage. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 8-9 month applied in the early spring. One application gives all the nutrients the plant requires.
