- Description
-
Petty Spurge, is a herbaceous annual growing to about a foot high. It is a small, branched, upright plant with pale geen foliage and stems. It resembles leafy spurge (Euphorbia esula), but differs in that it is smaller in stature and does not spread by underground runners. It prefers moist, shady locations, but will grow and spread in most disturbed areas. This plant flowers most of the year.
Petty Spurge produces distinctive bracts (modified leaves) below small, pale green flowers. It s native to most of Europe, North Africa, and Western Asia and is widely distributed in North America. It can typically be found on cultivated, arable land, gardens, and other disturbed areas. Outside of its native range, it is widely naturalized and often invasive. No specific data are available on seed dormancy and germination but plants are prolific seed producers and emerge beginning in the cool weather of fall and continue through late spring.
Diseases, Insects, and Other Plant Problems: No known diseases or other problems.
