Can I Grow Kaimi Clover in Colorado?

Kaimi Clover in Colorado — the short answer

Colorado is not one climate

Where Kaimi Clover Stands in Colorado

Zone Comparison

Plant data: Growable Ground Plant Database, compiled from FAO ECOCROP, USDA PLANTS, and university Extension sources — per-field provenance varies and is published with the dataset. State data: USDA ARS PHZM 2023, NOAA Climate Normals, NRCS SSURGO.

When to Plant Kaimi Clover in Colorado

Timing tuned to sub-state frost dates — Chaffee County, not the statewide average.

Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.

Soil + Drainage Fit

Kaimi Clover tolerates a wide pH range (pH 4-8) — 4 units, acid ground through alkaline — so soil acidity is rarely what limits it in Colorado. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5 and 7 — worth knowing before you decide whether a Colorado soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Colorado site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

What Else to Consider for Kaimi Clover in Colorado

Zone compatibility tells you about winter cold survival — but Colorado growers also need to think about:

What to actually do about these — and the constraints that apply to every Colorado grower, not just kaimi clover — is covered on the Colorado growing guide.

Timing shifts within Colorado

Colorado isn't one climate. In Chaffee County, the last hard freeze (28°F) holds until about Jun 12 — roughly 38 days later than the recorded state median — so plant kaimi clover to your county's window, not the statewide date.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.

Where in Colorado Kaimi Clover Is Zone-Hardy

Kaimi Clover is rated for USDA zones 8–11. No Colorado county reaches it. Even Mesa County, the state’s mildest winter at zone 7a, sits below the plant’s zone 8 floor — so in open ground this one needs winter protection here, or a container that comes under cover.

Across those 64 counties Colorado’s winter-low ladder runs from zone 4b in Alamosa County to zone 7a in Mesa County — 2.5 USDA zones of spread, which is 25°F between the two counties’ average coldest night of the year. None of that range reaches the band kaimi clover needs, so here the statewide answer really is the answer.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Kaimi Clover’s zone 8–11 band: Hardy to zone 8a: Tropical Plants Database (Useful Tropical Plants) lists -13 °C, converted to zone 8a; USDA PLANTS Database lists 6 °F, converted to zone 8a, checked Oct 2026. Ceiling: not verified.. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Kaimi Clover draws honeybees, native bees, and butterflies (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, kaimi clover can only work that bloom inside Colorado's frost window — roughly 155 days, opening after the last 28°F freeze (Apr 25 - May 19) and closing at the first (Sep 29 - Oct 16), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Good to Know Before You Plant Kaimi Clover

Colorado Cooperative Extension

For Colorado-specific cultivar recommendations, planting calendars, and pest pressure for kaimi clover, the canonical source is Colorado State University Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Kaimi Clover native to Colorado?

No — the USDA PLANTS Database lists Kaimi Clover as introduced rather than native in the Lower 48, so it is not part of Colorado's native flora. It grows here as a garden plant; pairing it with a few Colorado natives keeps local pollinators fed too.

Looking for plants that belong here? The Colorado growing guide lists plants that USDA PLANTS records growing in Colorado and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.
