These beautiful shrubs never fail to delight me. They are shrubby legumes with bright pink flowers and delicate pinnate foliage.
They prefer full sun and a well drained soil.
The first to flower here is Indigofera hebepetala, it makes a wide spreading shrub and flowers on bare wood in early May. It looks a bit like a miniature Judas tree.
Indigofera pendula comes out later and is a more fastigiate grower. It has pinky-lilac flowers that hang from the branches for many weeks.
Indigofera subverticillata beats the lot.
It starts in June and seems to go on all summer and into the autumn. The flowers are pink but fuller and with a hint of peach. Mine is 8' high and was undeterred by last winter - but I do grow it against a wall.
