Euphorbia cyparissias Cypress Spurge ( Euphorbia cyparissias ) is a plant in the genus Euphorbia , which is native to Europe and was introduced to North America in the 1860s by the colonists as an ornamental plant. It is sometimes called "Graveyard weed" as it is often seen in country graveyards. In its natural setting, Cypress Spurge thrives in dunes, pannes, coastal headlands and grasslands; in North America it is commonly found in the dry, gravelly soil of roadsides, pastures, and meadows. Cypress Spurge thrives in open, disturbed areas rather than forests or highly cultivated soil. It reproduces by seeds and also by the very well developed underground roots. It usually has a height of 10-80 cm (6-12 inches). Its petal-like bracts are usually green-yellow, maturing to purple or red from May to August. Cypress Spurge grows a fruit that, when mature, explodes to spread seeds up to 16 feet (4.9 m). However the plant also reproduces through lateral root buds which allows it to spread quick and densely. It can be easily identified by its

Other sources allege that the milky juice of the plant is toxic and causes irritations on contact with the skin. The sap may also irritate the eyes, mouth, and gastro-intestinal tract. This plant is considered a noxious weed in many places, including the state of Colorado. Like most non-native plants, it infringes upon the growth of native species. The Spurge is known to be harmful to cattle and horses, but not sheep. The hardy Spurge can be difficult to control; several species of European insects were released in North America in this effort. Certain beetles and fleas have been found to be effective, but those may pose even more risk to native plants than the removal of the cypress spurge itself....
