Description
It is an annual plant.[1] They are hemiparasitic plants. This species is a vigorous parasite. It formed haustoria on all 19 commercial species included in Appendix III. No clear host preference was shown, although hardwood species supported more parasitic attachments than pine species. [2] Common name are Slender gerardia and Slenderleaf false foxglove.
Distribution
Agalinis tenuifolia is the most widely distributed throughout eastern North America [2]
Ecology
Habitat
Agalinis tenuifolia commonly grows in distrubred sites, including clear cut areas. Large populations may also be found growing at the margins of ditches and in other wet or moist habitats. [2] It can be found in undisturbed grasslands and areas with low soil nutrients. Native vegetation, often including Agalinis tenuifolia, can be completely destroyed and replaced by weeds and soil nutrients increase dramatically when Ring-billed Gulls and other species of gulls nest from April to June.
