Smooth Aster is a native perennial wildflower known for its violet-blue, daisy-like flowers. They bloom later in the season, from late summer to early fall. The flowers attract a variety of pollinators, including bees, butterflies, and other beneficial insects. It also serves as a host plant for the Silvery Checkerspot (Chlosyne nycteis) and Pearl Crescent (Phyciodes tharos) butterflies, further enhancing its ecological value. This easy-to-grow wildflower is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.

The Smooth Aster’s non-aggressive root system allows it to spread slowly, and it is more likely to reproduce by seed, which can be controlled through deadheading. 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.

Pacific Anemone is a native perennial wildflower with buttercup-like blooms. The flowers can be a variety of colors, including white, pink, and dark red. The deeply cut leaves add a unique texture to the landscape. The flowers bloom from May to August, providing early-season nectar and pollen for insects. They attract a variety of pollinators, including bees and butterflies.

As the flowers fade, they become fluffy white seed heads, which birds often use in their nests. They can spread readily through self-seeding; to limit their spread, regular deadheading is recommended. Tolerant of drought and poor soils, the Pacific Anemone is well suited for wildflower gardens, pollinator gardens, and naturalization projects.

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.
