Berseem Clover is an annual grown for its pods, ready to pick about 90 days after sowing. It's hardy across USDA zones 3 through 9. Its late spring flowers are a real draw for honeybees, native bees, and butterflies, even though the pods are the prize. A nitrogen-fixer, it draws nitrogen from the air and feeds it back to the soil — turn it under or leave the roots in place, and the next planting inherits a richer bed.

What Berseem Clover is
Berseem Clover grows as an annual and reaches around two feet at maturity. It blooms in late spring.
How to grow Berseem Clover
Berseem Clover grows in USDA zones 3 through 9 and is ready to harvest about 90 days after planting. Berseem Clover does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 8, on well-drained ground. It needs around 1,000 growing degree days to mature and a growing season of at least 60 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant berseem clover in full sun with at least 6 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat.
Match the soil
Berseem Clover prefers pH 5 to 8 (Growable Ground Plant Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band. It fixes its own nitrogen, so skip the high-nitrogen feed and instead dust the seed with a matching rhizobium inoculant at sowing.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Berseem Clover is ready about 90 days after sowing (SARE; USDA-NRCS). Pick the pods young and tender, before the seeds inside fully swell.
Where Berseem Clover thrives
Berseem Clover is hardy across USDA zones 3 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 3–9 spans average winter lows from -40°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 42 outright and splits 9 more down the middle — and which side of that line your land sits on changes the answer.

Where Berseem Clover stands, state by state
Berseem Clover is rated for zones 3–9 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 42 sit fully inside that band, the line runs through 9 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

How we know this about Berseem Clover
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Berseem Clover in my zone?
Berseem Clover grows in USDA hardiness zones 3 through 9 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Berseem Clover take to grow?
Berseem Clover is ready to harvest about 90 days after planting (SARE; USDA-NRCS). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Berseem Clover?
Berseem Clover is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Berseem Clover need?
Berseem Clover needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Berseem Clover need?
Berseem Clover prefers soil pH 5 to 8, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Berseem Clover attract pollinators?
Yes — berseem clover's flowers are a strong nectar and pollen source for honeybees, native bees, and butterflies. (Source: Pollinator Partnership.)
Is Berseem Clover safe for pets?
Berseem Clover is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
