Product Details
While the names are similar, crimson clover is different than red clover. This annual clover has larger, elongated flower heads with deep red, long-lasting blossoms that invite beneficial insects, such as ladybugs and bees. Like other clovers, crimson clover fixes nitrogen, but it's faster growing for quick benefits to your garden. Crimson clover grows best in cool weather, so grow it as a spring or fall cover crop. For maximum nitrogen, till, mow, or cut back with a weed trimmer at end of bloom and before seeds form. Grows in a variety of soils but does best if soil is well drained. Plants tolerate some shade so you can sow crimson clover in between rows or under tall plants, such as with corn or under fruit trees. A beautiful addition to fill spots in flower beds and borders. Flowers can be harvested and dried to make a delicious tea with a light, refreshing flavor.

- Ms. p. t.Verified ReviewerRated 5 out of 5 starsOct 26, 2025Incredible Germination Zone 9B San Jose
Germinated within five days and creates very sturdy seedlings. One pack was enough to fill in my 10’ x 4’ raised bed. I also bought a 1/4 lb of crimson clover from a different reputable brand (Johnnys) that I used on two other beds. BI had better and faster germination rates (4-5 days compared to 15-18 days) as well as a darker colored seed. I followed the back of the packet plus used the tickle tap method from Jacques and it worked pretty well. :) Loved this seed packet. Very viable seeds and I can’t wait for the nitrogen fixation nodules to form!

Grew well in poor unimproved clay soil in partial shade. Big beautiful flowers. Did not re-seed so they are not invasive.

I scattered the seeds on the bed on Wednesday and this morning, Friday, I saw quite a blanket of seedlings. I’m very pleased.
