Mature transplants added to a woodland degraded by cattle grazing in Wisconin were "healthy" in the six years that the plants were monitored, and with low mortality; the authors did not report whether they reproduced (Ellarson and Craven 1982) .
Transplants in a field study had 50% survival after 7 years; phlox self-sows (Mottl et al. 2006). New roots form where nodes of stem contacts damp soil (Sperka 1973); has extensive vegetative spread, forming patches or colones (Barkely 1986, Gleason and Cronquist 1991, Runkel and Bull 2009),
Seeds few and not easy to collect (Sperka 1973).
Pollinators: Limited to butterflies and long-tongued bees and flies due to the narrow tubes of the flower (Blanchan 1900).
Fun fact: Upper stem and flower stalk (below the receptacle where the flower parts attach) are coated secretion that traps crawling insects and prevents them from consuming nectar (Blanchan 1900).
