Trumpet Creeper vine was being cultivated in Massachusetts as early as the 1840's, when George Emerson noted in his Report on the Trees and Shrubs growing naturally in the Forests of Massachusetts (1846) that individuals were "extensively introduced as ornamental plants, but are not found growing naturally in this State." As the animated image below indicates, the first citing of C. radicans growing on its own came not long after in the town of New Bedford (Bristol County). It is interesting that there appears to be a lack of records for this species in the western portion of the state. This page will be updated as new records are located.
Though C. radicans has escaped from cultivation, it is not aggressively
invading natural habitats. This is surprising, considering its clinging
habit, heavy production of winged, wind-dispersed seeds, and the fact that
the species often becomes unmanageable in the southern United States, its
native habitat (Neiring
and Olmstead 1979).
