Summary ⁴

Trifolium hirtum is a species of clover known by the common name rose clover. It is native to Europe, Western Asia, and North Africa. It is present elsewhere as an introduced species and it is cultivated as a cover crop and animal fodder. It was introduced to California from Turkey in the 1940s as a forage crop, and today it is a widespread roadside weed there.

Adaptation ⁵

In California, rose clover is widely adapted to climates below 6000 feet elevation except the coastal fog belt and areas receiving less than 10 inches of rain. It is adapted to well-drained soils. It does well on strongly acidic to moderately alkaline soils, but does best if the pH ranges between 6 and 7. It germinates as well as other legumes in the cold, fall weather, but not as well as annual grasses. It performs best when fall rains occur while the weather is still relatively warm, enabling it to compete favorably with grasses. It is less tolerant to low pH, but tolerates drier conditions than subclover.

Distribution ⁶

Rose clover is found in the California Floristic Province, but is also sporadically located in the eastern United States. It is usually found in disturbed areas and roadsides. For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.
