July 2014 Page 1 of 3 CT Early Detection and Research Lists Invasive and Potentially Invasive Early Detection List

These are known to be invasive or potentially invasive in and are on Connecticut’s list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. See the CT Invasive and Potentially Invasive Plant list for synonyms and full nomenclatural information.

If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at [email protected]. Aquatic species reports will be forwarded to DEEP. Be sure to include as much detail as you are able (attach photographs if possible) and provide your contact information. You may also report these and other species online at www.EDDMapS.org. EDDMapS is an online mapping program that can be used to track invasive plants.

*Present in Connecticut means listed as occurring in the state by the Flora Novae Angliae by Arthur Haines or a documented occurrence recorded with the Invasive Plant Atlas of New England (IPANE) or the George Safford Torrey Herbarium (CONN) at the University of Connecticut. Plants do not need to be present in Connecticut prior to being listed on the state’s invasive or potentially invasive plant lists.

This is a list of plants about which more information is desired. This is not a regulatory list or an invasive plant list. Plants are not necessarily listed here prior to inclusion on an invasive plant list. Rather, more information about these plants and their occurrence in the state is desired and current records are limited. The Invasive Plants Council is the body responsible for the Invasive Plant List under CT General Statutes Sec. 22a-381b. To request a species be examined by the Invasive Plants Council, fill out the “Guidelines for submitting a Candidate Species for Council Review” document available on the IPC website at http://cipwg.uconn.edu/criteria-for- listing/.

If you find these species: Report your findings online at www.EDDMapS.org.

Scientific Name Common Name CT Inv. status Present in CT?* Actinidia arguta Hardy Kiwi Not listed Yes This plant was discussed by the CT Invasive Plants Council in 2010. No IPC action was taken. Plants may not be producing viable seeds and may not be spreading to new areas. DOT controlled plants at a site in west central CT where this plant was reported. Akebia quinata Chocolate vine Not listed Yes Sometimes found at old/historic home sites. Evidence of new dispersal is lacking. Anthriscus sylvestris Wild Chervil Not listed Yes Native to Europe. Reported to be spreading in CT and throughout New England. Aralia elata Japanese aralia Not listed Yes Native to Asia. Found in some New England states. Eragrostis curvula Weeping lovegrass Not listed Yes Native to Africa. Found in southern New England. Hydrocharis morsus-ranae common/European frogbit Not listed No Native to Europe. Not known to be present in CT. Found in VT. Kummerowia striata Japanese clover Not listed Yes Native to eastern Asia. Found in southern New England. Lespedeza cuneata Sericea lespedeza Not listed Yes Native to eastern Asia. Also found in MA. Ludwigia peploides ssp. glabrescens Fltng. primrose-willow Not listed No Native elsewhere in US but not native in CT. Oplismenus hirtellus Wavyleaf basketgrass Not listed No This plant was discussed by the CT Invasive Plants Council in 2012. No action was taken. The IPC may review this plant annually. Phellodendron amurense Amur corktree Not listed Yes Native to eastern Asia. Present in several locations in Connecticut. Phyllostachys spp. Various bamboo species Not listed Yes Phyllostachys aureosulcata and other Phyllostachys species were examined for listing in 2010 and 2012. Species in the Phyllostachys did not meet criteria set forth in CGS Sec. 22a- 381b. There is a lack of evidence that species in this genus spread to new areas of the state unless they are intentionally planted, moved, or improperly discarded.
