Petty spurge (Euphorbiaceae) is a small, branched, upright plant with pale green foliage and stems, resembling leafy spurge (Euphorbia esula) but smaller in stature and not spreading by underground runners. Plants produce distinctive bracts (modified leaves) below the small flowers. Flowers are small and pale green in color. Petty spurge is widely distributed in North America but is a relatively new introduction to the nursery industry. No specific data are available on seed dormancy and germination but plants are prolific seed producers, and emerge in cool weather of fall through late spring. Recent research suggests it is controlled by most broad-spectrum nursery herbicides. [TOP]
