Q: Where have people planted carnivorous plants as non-natives?

A: Carnivorous plants have been planted out all over the place, where they are not native.

This page is very much a work in progress.

My main interest in this page, is to help those botanists who are trying to understand a population of plants that may seem out of the way. Do you have a report of non-native carnivorous plants? Send it my way, and I will list it here.

Canada
British Columbia:
Darlingtonia californica has been planted in at least one bog (Teichreb 2006).

Germany
Sarracenia purpurea has been planted in at least one bog (Gebühr 2006).

Ireland
Sarracenia purpurea has been planted in at least one bog (Nelson 1986).

Jamaica
Dionaea muscipula and Sarracenia were introduced to the Mason River field station (Clarendon) from 1969-1975 (Campbell 2005).

New Zealand
Utricularia geminiscapa has been detected (Salmon 2001).

USA
Arizona:
Graham county--I know of one horticulturist who planted Sarracenia purpurea on Mount Graham, but these plants have probably not persisted (P. McMillan, pers. comm. 1990)

California:
Butte Norte county--A lone population of Darlingtonia californica in this county is probably the result of an introduction (Pers. observation)
Del Norte county--I have removed Drosera capensis and Sarracenia hybrids from sites here. (Pers. observation)
Fresno county--Utricularia inflata is reported from ponds at a city pond (Rondeau 1991).
Mendocino county--a huge number of carnivorous plants have been planted, against the wishes of the owners, at a preserve owned and managed by The Nature Conservancy (Rice 2002a).
Plumas county--Drosera hybrids and Sarracenia have been planted at Butterfly Valley Botanical Area, the former resulting in claims for Drosera anglica in the area (Rice 2005c). Also, Utricularia subulata was seeded at Willow Lake around 2001, but the seeds apparently have not germinated (Anon., pers. comm. 2002).

Florida:
Liberty county--Dionaea muscipula has been planted in Apalachicola National Forest at a number of sites. Although the nativity was formerly questioned, the planter and the history behind these plantings is now fully documented (Pers. observation; P. D'Amato, pers. comm. 2007).

Maryland:
Prince Georges county--Drosera filiformis has been planted here. A site in Charles County is similarly suspect (Rice 2011a).

New Jersey:
Ocean county--Sarracenia rubra and Sarracenia minor have been planted in the Pine Barrens (Pers. observation). Aldrovanda vesiculosa has also been planted there (R. Sivertsen, pers. comm., 2005).

New York:
Orange county--Sarracenia flava and Aldrovanda vesiculosa has been planted here (R. Sivertsen, pers. comm., 2011).

North Carolina:
Hanover county--Sarracenia leucophylla and other species have been planted in "Wilmington Nature Trail" (Pers. observation).

Ohio:
Licking county--Sarracenia purpurea was placed at Buckeye Lake Cranberry Bog (Risner 1987).

Texas:
Tyler county--Sarracenia leucophylla has been planted, and is hybridizing with native Sarracenia alata (M. Howlett, pers. comm., 2006).

Virginia:
Caroline county--Aldrovanda vesiculosa, Drosera filiformis, and others have been planted here (Pers. observation).

Washington:
Cowlitz county--Utricularia inflata has been introduced, either by carnivorous plant enthusiasts or aquarists (Pers. observation).

Sweden
Sarracenia purpurea has been planted in at least one bog (Gebühr 2006).
