- Herbaceous perennial
- USDA hardiness zones:
Cypress spurge is an erect, branching, rhizomatous perennial which typically grows to 12\ tall and can rapidly spread to form a bushy ground cover. Numerous tiny flowers appear in umbel-like clusters in spring. Flowers lack petals and sepals, and primarily consist of showy lime-yellow bracts which age to red. Narrow, bluish-green, linear leaves (to 1.5\" long). Stems and leaves contain a milky sap which is poisonous. Plant foliage superficially resembles that of a tiny spruce or cypress tree, hence the common name."
- Full sun
Best grown in dry, well-drained soils in full sun. Quite tolerant of poor soils, including rocky, sandy ones. Eight to ten plants per square yard are sufficient to quickly form a dense ground cover. Spreads by rhizomes and can be quite invasive, particularly in rich, moist soils. Also freely reseeds.
Size and growth:
- 0.75 to 1.0 foot
- 1.0 to 1.5 feet
Bloom / flowers:
- April - June
- Yellow aging to red
Natural, Showy flowers, Ground cover, and Yellow
Western, central and southern Europe
Best as a ground cover on dry, sunny slopes or other sunny areas that are well-spaced from perennial plantings. Probably too invasive for the border.
No serious insect or disease problems. Invasiveness can be a significant problem, particularly if plants are grown in close proximity to valuable garden perennials.
