Chamaecytisus purpureus

With its spreading and bushy habit and its magnificent purple-pink flowering, the Chamaecytisus purpureus, also known as Purple Broom, is an attractive ground cover bush. In late spring and early summer, it forms a real carpet of flowers that brightens up even the driest areas of the garden. Hardy, drought-tolerant, and easy to grow, the Cytisus purpureus will offer you its splendour without any difficulties! Its compact size also allows it to be grown in containers to create a lovely flowering cascade on your terraces and balconies.

Chamaecytisus is a group of shrubs native to the Mediterranean and the Canary Islands, closely related to the genus Cytisus to which they once belonged. The genus includes shrubs of varying sizes, with trifoliate foliage and clusters of flowers in various colours. The Purple Broom is a dwarf bush with a wide and spreading habit. Its branches are highly branched, initially erect and then arching, or even creeping. When fully grown, it reaches a height of approximately 45cm (17.7in) and a spread of 70cm (27.6in).

Chamaecytisus purpureus makes an excellent ground cover thanks to its bushy and spreading growth. Its branches are green and smooth, growing in all directions. They bear deciduous dark green foliage, composed of alternate leaves with petioles, measuring 1 to 3cm (0.4 to 1.2in) in length. The leaflets are obovate and usually smooth. It is a sucker-forming bush with a trailing root system, making it suitable for use on slopes and embankments to stabilize the soil. In May and June, Chamaecytisus purpureus displays magnificent flowering in shades of pale pink to violet. Highly appreciated for the uniqueness of its multicoloured flowers, it forms a real carpet of flowers that will not go unnoticed in the garden! The branches are covered along their entire length with numerous small butterfly-like flowers with a diameter of 1 to 2.5cm (0.4 to 1in). They appear singly or in groups of 2 or 3, in the axils of the leaves. Black, flat, and hairy pods, which disperse their seeds suddenly with a dry snap, then take over. It is advisable to prune the bush before fruiting to avoid unnecessary stress.

Chamaecytisus purpureus naturally grows in dry places, on rather acidic soils. It prefers sunny exposures (but can tolerate semi-shaded situations), poor and well-drained soils, neutral or slightly acidic. However, it also tolerates slightly chalky soils. Choose its location carefully as it does not tolerate transplanting well.

Cytisus purpureus has excellent hardiness, allowing it to withstand temperatures below -15°C (5°F). Plant your Chamaecytisus purpureus in sandy soil without adding fertilizer. If your soil is heavy, lighten it with sand, or gravel. Water it regularly during the growing season for the first two years after planting. Once established, this small Broom offers good drought tolerance, heat resistance, and disease resistance. A light pruning after flowering is sufficient to keep it vigorous. Accommodating and easy to maintain, Chamaecytisus purpureus will find its place in most gardens! With its spreading and carpeting habit, Cytisus purpureus makes an excellent ground cover. It will provide abundant vegetation and flowering in your rockeries, flowerbeds, and borders. Combine it with plants that thrive in dry and poor soils, with colourful blooms such as Bulbine frutescens 'Hallmark', Ceanothus prostratus, or Salvia grahamii. Chamaecytisus purpureus can also be grown in containers to decorate terraces and balconies with its cascading violet-pink flowers.
