Purple Prairie Clover is a native perennial wildflower known for its striking purple blooms. The flower heads grow as dense spikes on tall stems, with each flower head containing many tiny blossoms. Blooming for 4–6 weeks in the summer, it attracts a variety of pollinators, including bees and butterflies.

The high protein content of the Purple Prairie Clover makes it excellent forage for wildlife and birds like to feed on its seeds. As a nitrogen-fixing plant, it enriches the soil, improving fertility and benefiting nearby vegetation. These ecological contributions make it a great choice for pollinator gardens, prairie & rangeland restoration, naturalization, and re-vegetation efforts.

This drought and heat-tolerant plant thrives in various soil conditions, including rocky soil, making it remarkably easy to grow in challenging environments. As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.

Cow Parsnip is a native perennial plant that grows tall with very large leaves and broad clusters of white flowers. It grows quickly, providing quick cover in disturbed areas.
Its flowers are large and plentiful, providing nectar and pollen for bees, flies, and butterflies. Its seeds are eaten by birds and small mammals. The young shoots of the plant are edible, but care must be taken as the sap of this plant can cause skin irritation (see below).
Note: The sap of the Cow Parsnip can cause phytodermatitis when exposed to ultraviolet light (sunlight). This can cause rashes or even burns. Care should be taken if pruning or handling this plant.
