How to Grow and Care for False-lupines

False Lupin, or Thermopsis montana, gets its Latin name because it grows in the mountains, or at higher elevations. This pretty flower is often grown as an ornamental flower, but is suspected to be toxic.

Lanceleaf thermopsis (Thermopsis lanceolata) is a good garden plant because of its attractive yellow flowers and its resilience and ease of growth. It looks similar to traditional garden lupins but has a more bushy growth form. Lanceleaf thermopsis emerges from the soil in the spring as a unique black color but quickly fades to green. The specific epithet, lanceaola, means "spear-shaped" and refers to the plant's long thin leaves.

Prairie thermopsis (Thermopsis rhombifolia) is indigenous to North America. There, you’ll find it flourishing in the Rocky Mountains and the Great Plains. The brilliant yellow flowers can be used to make dyes, and wildlife love to eat both the stems and long green seed pods.

California goldenbanner (Thermopsis californica) is endemic to California. The species includes several varieties, some of which are commonly called "false lupine" due to their appearance. California goldenbanner is considered an "imperiled species" due to its low numbers, limited range, and ease with which it can be destroyed by livestock or off-road vehicles.

Chinese false lupin (Thermopsis chinensis) is a popular ornamental plant in both natural and hybrid forms. It is prized for its attractive yellow flowers and ease of growth. The flowers look best in mass plantings in meadows and perennial gardens. These flowers are a great way to attract bees to the garden.
