It’s time to love pink, and how can anyone say no to a flowering shrub that produces upright racemes of soft pink pea blossoms from late spring right through fall. Indigofera amblyantha, commonly known as Chinese Indigo, is a member of the legume family, so it fixes its own nitrogen from the soil and thus is a candidate for poor soil conditions. It asks for full sun and good drainage, and is hardy in zones 6-9. It wants to be a multi branched shrub but we have seen it charmingly pruned to a single leader (to appear as a small tree). In zones with severe winters, Indigofera amblyantha may get winter die back, so we suggest that if you try this pruning treatment, do so on plants located in a sheltered spot and consider it as an experiment. Then again, should die back occur, you can always enjoy this plant as the bushier shrub it is more inclined to be.
Attractive companion plants for Indigofera amblyantha are Calamintha nepetoides, Euphorbia ‘Blue Haze’ and Sedum ‘Maestro’.
