Tomcat Clover (Trifolium wildenovii) is native to western North America, and specifically found along the Pacific coast from Mexico to British Columbia. It primarily occurs in meadows, grasslands, and open woodlands where it thrives in a variety of soil types and climatic conditions. Plants are highly variable depending on growing conditions, and in moist conditions can feature lush green foliage and fewer, larger flowers, or growing more ephemeral and compact with many blooms in poor soils.
Tomcat Clover typically blooms from late spring to early summer, with its flowers reaching their peak during the warmer months. The exact blooming period may vary slightly depending on conditions. Tomcat Clover has a strong relationship with various native bees and bumblebees. The plant also supports a range of wildlife, including birds that feed on the seeds and mammals that browse on the foliage. It is often seeded as a supplemental range forage for livestock, providing a valuable food source for grazing animals.
Tomcat Clover is adaptable to a variety of soil types, including sandy, loamy, and clay soils. Tomcat Clover is also a nitrogen-fixing plant, meaning it forms a symbiotic relationship with nitrogen-fixing soil bacteria, enriching the soil. Seeds can be sown up to 1/8” deep in prepared soil in the early spring. Keep soil consistently moist until seedlings have established.
