Chamaesyce hyssopifolia

Common Name(s):
Hyssop spurge

Spurges (Chamaesyce spp., and the Euphorbiaceae family) are summer annual weeds that flourish in warm weather, but in warmer climates some can persist into late fall. Plants flower in summer and early fall then die after frost. Flowers are greenish-white. Spurges are some of the most common warm-season weeds. Each exudes a milky sap when stems or leaves are broken.

Management Guidelines for Spurges: Because spurges flower when young and have little or no seed dormancy, weed populations can increase rapidly. Remove plants when young to reduce seed production. They are time consuming to hand weed due to the number of seedlings that form. Some species may forcefully discharge seeds. Spurges are well mangaed by most preemergence herbicides labled for use.

The foliage of hyssop spurge (Chamaesyce hyssopifolia), is similar to nodding spurge (Chamaesyce nutans) with an upright or ascending growth habit, and leaves are longer than wide with an uneven base and lack hairs. Plants have long, smooth, branched stems, often red in color, and a stout tap root. It is a prolific seeder; seeds have little or no dormancy and germinate quickly. It is somewhat more tolerant to herbicides than the other spurges.
