Cultural Information

The pods are sticky with six teeth at the top of the calyx. Plants decline quickly after flowering and should be marked for later seed collection. The capsules should be harvested indivdually as they mature and dryed in paper bags. The seeds may be planted fresh or stratified at 33-40 degrees F for 30 days (Phillips, 1984, Shirley 1994, Steffen 1997). There are 160,000 seeds/lb. and the recommended planting rate is 10 lbs./acre. Stem cuttings, with at least one node below soil level, may be rooted under mist. Clumps may be divided in fall (Phillips 1985).

Animal Use

Attracts hummingbirds.

Natural History

A weedy plant common in moist, grassy areas, meadows, prairies, and in waste places throughout the eastern United States, from Canada to Mexico. It has been collected throughout most of Louisiana and Texas. Its common name, "sleepy catchfly", results from the sticky hairs and a glutinous exudates that forms bands around the internodes of the stem of this species and which trap insects. Individuals with no petals are sometimes found.

Habitat

Sandy soil or waste places.
