Neon Flash Spiraea is a colorful, low maintenance, and multi-purpose shrub.

Late spring to fall you'll be drawn to its vibrant neon red blooms that rest on a neat mound of green foliage. If deer and rabbit are an issue on your property, consider planting Neon Flash Spiraea for its deer/rabbit resistance. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.

Hairy Golden Aster is a native perennial wildflower known for its clusters of bright yellow, daisy-like blooms. They bloom from mid-summer into fall, providing late-season colour and a valuable nectar source for pollinators, including a variety of bee species.

Flowers mature into fluffy seed heads and can self-seed readily. Removing spent blooms helps manage their spread, but some people will choose to leave a few seed heads to provide food for birds. Hairy Golden Aster grow in bushy clumps, tolerates poor sandy soils, and once established, are among the most drought-tolerant wildflowers. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping 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.
