Junegrass is a native, low-growing perennial bunchgrass commonly found in prairies and open woodlands. It is a great choice for prairie restoration and naturalization projects or an attractive accent in ornamental plantings. Spear-shaped seed heads rise above the gray-green lower leaves, maturing to a tan color. Flowering earlier than other upright prairie grasses, it greens up quickly in spring and maintains its appeal well into the fall. It is shorter in stature and rarely forms thick stands, which adds to its understated visual appeal.

Adapted to cooler climates, Junegrass thrives in well-drained, rocky, sandy, or gritty soils and can tolerate drought, cold, and high altitudes. It actively grows in spring and fall when soil temperatures are cool, but in areas that are too hot or humid, it may go dormant by late summer.

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.

Silky Lupine is a native perennial wildflower known for its upright spikes of blue to violet flowers. Blooming from late spring into summer, the nectar-rich, showy blossoms attract a variety of pollinators, especially bees and butterflies. The plant’s fine, silky foliage provides soft texture and visual interest, enhancing landscapes throughout the growing season.

Silky Lupine is a nitrogen-fixing plant that enriches soils and supports surrounding vegetation. Its deep roots stabilize soil, and it spreads naturally by ejecting seeds from drying pods. If spread isn’t desired, new seedlings are easy to remove. While it is foraged by some wild animals, it contains alkaloids that are toxic to livestock. Silky Lupine is well-suited to pollinator gardens, naturalization plantings, erosion control, and ecological restoration projects.
