A cute - but vigorous - perennial. Can be used as a groundcover.
Common name : Cypress spurge
Scientific name : Euphorbia cyparissias
Family : Euphorbiaceae
Category : Perennials
Type of plant : Perennial
Euphorbia cyparissias - the cypress spurge - is a species native to dunes and grasslands in Europe, and introduced to North America, originally as an ornamental plant.
It is a perennial growing to 40 cm (16 in) tall, with small and linear, 4 cm (1.6 in) long leaves and green-yellow petal-like bracts, maturing to purple or red from May to August.
E. cyparissias is considered a noxious weed in many places, including Colorado in the United States.

Plant my cypress spurge
Plant your spurge in the sun or possibly semi shade in neutral limestone soil, even stony, from February to April and from September to November. Euphorbia prefer a soil not too rich but very drained. They are resistant to drought.
Prepare the soil with some light digging (to decompact without necessarily turning it over with a pitchfork or broadfork), hoeing, and raking. Plant leaving 30 cm between the plants. Tamp the soil down well so that the roots are not in contact with air, then water generously.
Water my cypress spurge
During growth, water once or twice a week.
Water adult plants by big inputs even if you do it less often; the plant will develop a better root system if it has to fetch its water in depth. When watering, wait until the water that you pour stop rushing into the ground, and forms a small puddle. Unless otherwise specified, do not wet the foliage: plants "drink" by their roots.
Weed my cypress spurge
Avoid hoeing the soil too close to euphorbia strains because their roots are fragile.
In the case of perennials, weeding also means arbitration in your massif; do not let the most vigorous develop at the expense of the slower ones.
Propagate my cypress spurge
Multiplication of perennial euphorbia is done by dividing the tuft in March every 2-3 years.
Mulch my cypress spurge
Mulching the perennial plants will save you from watering and weeding and will even fertilize the soil a bit as it decomposes. When choosing, know that dry wood chips are the most inert, but they will last for a longer time. Fresh wood chips and leaves enrich the soil but must be changed often. Grass cuttings are to be used mixed with something else in a layer that is at most 1 cm thick. Mulch with at least 3 cm of thickness to ensure it works and isn't simply a cosmetic effect.
Cut down my cypress spurge
The regular pruning of euphorbia is not essential. However, we can cut down the stems in spring or fall, to limit the development of the plant.
Trim right after the end of flowering to prevent seeds from sowing spontaneously.
Simply cut the flower stalks about 5 cm above the ground.
