Silky Lupine
Nuttalls Sunflower

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.

Nuttall’s Sunflower is a native perennial wildflower known for its bright, golden-yellow blooms. Flowering from mid to late summer, it offers a late-season nectar source for various bees, butterflies, and other pollinators, while the seeds provide a fall food source for birds. The upright growth habit adds structural height and visual variety to your landscape.

Nuttall’s Sunflower can be found growing in moist to wet meadows, prairies, and open spaces. It can spread quickly via underground rhizomes, making it ideal for large-scale plantings. It is well-suited for naturalization, soil stabilization, riparian zones, and wetland restoration projects. If planting in smaller urban yards or gardens, extra care and maintenance will be required to limit its spread.
