Indigofera himalayensis 'SILK ROAD' Himalayan indigo

Himalayan indigo is an unusual shrub from the mountainous parts of Pakistan, Nepal and India. Its deciduous, compound leaves are soft green and look like miniature locust leaves. Flowers cannot be compared to anything you normally see growing in Central European gardens. They are pea-like, formed in erect or partly pendent racemes where individual flowers start opening up at the bottom and continue upwards. Silk Road is a profusely flowering variety with rich pink flowers from early until late summer. It blooms on continuously growing shoots.

Indigo forms a medium fast or fast growing shrub that can take full neglect but the result speaks for itself. We suggest growing it in very fertile, perfectly drained soil in full sun. Under such conditions you can expect a lovely, bushy and dense shrub with profusion of flowers from June until August, creating a typical atmosphere of its home. It can be cut back every spring to encourage new growths. Keep it mulched, especially in winter. Hardy to about -25°C (USDA zone 6) but is supposed to take a few degrees lower.
