Clip clean newly opened flower heads and dry quickly before browning. Fresh pink heads make the best tea and leave the plant to rebloom.
Red Clover
Trifolium pratense
Family Fabaceae
Red clover pulls double duty better than almost any small plant — plump rose-pink flower heads that bees work all season and herbalists dry for traditional tea blends, on a legume that's quietly fixing nitrogen into your soil the entire time it blooms.
Treat it as a working guest rather than a permanent lawn: a managed patch, a path edging, a living mulch between crops that hands its nitrogen to whatever follows. The tea is a traditional medicinal, so check interactions if that matters for you. Then sow a corner and let it work.
