Quick answer: Rhode Island has 181 native plants in this directory, 140 with a live listing as of 04 Nov 2026, and 20 with a lookalike alert — check before you buy.
Rhode Island has 181 native plants in this directory, from the Northeast region, growing in USDA zones 6b-7b. The typical last spring frost is around Apr 22 and the first fall frost around Oct 19, so most native seed goes in outdoors in late fall or winter. Of these, 128 tolerate some shade, 124 feed pollinators and 87 handle dry spells; bloom peaks in May. Good places to start: Northern blue flag, Seaside goldenrod and Butterflyweed.

Sow seed outdoorsPlant live plantsBothThis month
Oct 19 – Mar 23Sow seed: late fall into winter
Sow most native wildflower and grass seed outdoors. Many natives need weeks of cold, moist conditions before they sprout, and a Rhode Island winter does that for free.
Apr 22 – Jun 6Spring: after the last frost
Sow seed that needs no cold treatment, and set out live plants once the soil warms.
Aug 30 – Oct 12Plant: early fall
A strong second window for live plants and shrubs, while roots still have time to settle in.
Check each seed packet: a few species want spring sowing or special treatment. Frost dates are NOAA 1991–2020 normals (32°F, 50% chance) from 9 Rhode Island weather stations; your own yard may differ by a week or two.
