In the garden

Euphorbia cyparissias sits in the Euphorbiaceae as a low, mat-forming perennial that produces deciduous, linear leaves and a compact habit. Individual plants grow to 0.1–0.5 metres tall and commonly extend 1–1.5 metres across over two to five years; flowering occurs from May to September. The species is suited to open, sunny positions and tolerates periods of dry soil once it has established. Place plants in full sun on chalk, loam or sand where soil is moist but well drained or simply well drained; it copes with acid, neutral or alkaline pH. It is rated H5, so it will be hardy in most UK gardens, and will grow on south- or west-facing sites whether exposed or in sheltered spots. Keep soil free-draining to reduce the risk of winter saturation. Use Euphorbia cyparissias in mixed borders where a low ground cover is wanted, in containers for edging, or in rockeries. Space plants to allow their mat to develop without crowding neighbours. Plant individual specimens at least 1 metre apart to accommodate a 1–1.5 metre spread.
