By July, many gardens begin transitioning from the bright flush of spring into the warmth of summer. While some early bloomers are slowing down, the right selection of perennials can keep your landscape colorful for months to come. Better yet, many of these dependable plants provide valuable nectar for bees, butterflies, hummingbirds, and other beneficial pollinators.
Whether you’re refreshing an existing garden or filling empty spaces, these long-blooming perennials will help your landscape stay vibrant through the rest of summer and into fall.
Coneflower (Echinacea)
Coneflowers are among the most reliable perennials for season-long color.
They offer:
- Long-lasting blooms
- Excellent drought tolerance
- Seed heads that attract songbirds
- Outstanding pollinator value
Available in shades of purple, pink, white, orange, and yellow, coneflowers are a favorite in Maryland landscapes.
Rudbeckia (Black-Eyed Susan)
As Maryland’s state flower, Rudbeckia deserves a place in nearly every sunny garden.
These cheerful blooms:
- Flower from mid-summer into fall
- Thrive in full sun
- Attract bees and butterflies

Their bright golden blooms bring warmth and color to any landscape.

Its benefits include:
- Thick succulent foliage
- Clusters of late-season flowers

Planting now allows them to establish before their colorful blooms begin appearing later in the season.
They offer:
