Why is it a noxious weed?

Baby's breath is an ornamental species that has escaped cultivation to pastures and rangeland in some areas. Once established, it forms dense stands and is difficult to control.

How does it reproduce?

Baby's breath reproduces by seed with each single plant averaging 13,700 seeds. Wind appears to be the most important dispersal agent. Most seeds drop to the ground near the parent plant, but if the seed capsules do not open completely, the seeds may be carried lengthy distances before being dropped.

Where does it grow?

Baby's breath can withstand considerable variation in both temperature and moisture; it is most aggressive in areas of low rainfall.
