Cytisus x boskoopii Boskoop Ruby



Masses of bright red flowers

This shrub is a show stopping sight when in full flower during early summer. The rich, ruby red pea-like flowers cover the branches, creating a vase shaped plant for the middle of a sunny border. Bees love the blooms.


Happiest in full sun this hardy shrub is resistant to drought once established. It also loves seaside gardens where the almost leafless stems cope well with salt laden winds.


Best in a well drained soil, brooms are very drought tolerant once established. After flowering cut back the stems by two thirds to encourage the new shoots needed for next year's flowers.

Cytisus 'Boskoop Ruby' was awarded the Royal Horticultural Society's Award of Garden Merit in 1993.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
