Quick answer: Wyoming has 87 native plants in this directory, 62 with a live listing as of 04 Nov 2026, and 6 with a lookalike alert — check before you buy.
Wyoming has 87 native plants in this directory, from the West region. The typical last spring frost is around May 20 and the first fall frost around Sep 24, so most native seed goes in outdoors in late fall or winter. Of these, 66 feed pollinators, 59 handle dry spells and 38 are deer-resistant; bloom peaks in June. Good places to start: Rocky Mountain iris, Rocky Mountain penstemon and Common gaillardia (blanketflower).

Sow seed outdoorsPlant live plantsBothThis month
Sep 24 – Apr 20Sow 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 Wyoming winter does that for free.
May 20 – Jul 4Spring: after the last frost
Sow seed that needs no cold treatment, and set out live plants once the soil warms.
Aug 5 – Sep 17Plant: 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 96 Wyoming weather stations; your own yard may differ by a week or two.
