The Westchester Community College Native Plant Center has a list of native plants they consider garden worthy.
Please use this list as a starting point. Native plants often have very specific cultural requirements and success in growing them often depends on reproducing the native habitat. Many references can provide more information on the type of soil, etc. that would be best for a given species. Many of these plants are not available in standard nurseries, but are readily propagated from seed. FLNPS has a members’ seed exchange, and can provide information on propagation. Please see the note on collecting under “Status” below.
Abbreviations & Codes Used in Table:

Status: NY State or Finger Lakes population status – not necessarily legal status. “Exploitably vulnerable” plants are not indicated if populations are OK in the Finger Lakes. (This status includes nearly all ferns and orchids, and prohibits collection.)
