Where Birdsfoot Trefoil Are Found

This plant can tolerate both wet and dry soil conditions. In particular, Lotus corniculatus performs best on soil with a pH level between 6.2 and 6.5, making it tolerant of wet, acidic soil. Commonly, it flowers in late April or May, and the flowering continues until the middle of September.
Trefoil has been introduced to new areas, including North and South America, as well as Australia. It can grow from sea level to 3,500m altitude but performs well where there’s rainfall that ranges from 600–1,500mm alongside temperatures above -5 degrees Celsius in winter and 20-30 degrees Celsius during its growing season.
Furthermore, this flower doesn’t have any tolerance for shading—especially during its early stages, and it can even be planted on slow-growing grasses.

The Lotus corniculatus birdsfoot is sometimes called ‘eggs and bacon’ due to its red and yellow colour when the flower blossoms. Once completely open, the flowers appear a uniform yellow while sometimes keeping some patches of orange and red for a stunning appearance.
Each pod holds numerous seeds, and as the seeds dry, the pods twist and split to release more seeds that are then distributed and planted throughout your garden or amongst the wildlife.
Is It Invasive?
