Growing Zones 4-9
The Ruby Star Coneflower (Echinacea purpurea 'Ruby Star') produces large, intense carmine red, daisy-like flowers with a dark, raised, reddish-bronze pincushion-like center cone! The pinkish petals gently curve backward as the bold blooms stand tall on their reddish stems and green leaves.
These flowers grow on 40-inch tall stems from late spring through fall! Rising high above the leaves to display their bold blooms to attract plenty of bees and butterflies! Well-branched and full, these easy-to-grow perennials attract loads of pollinators to their summer through fall blossoms!
Once the chill hits the air and the flowers fade, the spikey domed centers remain through the winter to add texture to the snow, feed often visited by songbirds, Goldfinches, and other birds to feed on the seed, and add interest to dried arrangements! Hardy throughout USDA planting zones 4 to 9, these plants only spread about 2 feet wide.
Planting and Application:
This Coneflower is a hardy native cultivar and is a sun garden perennial, adding its bold hues to your garden beds and borders! Mix Ruby Star with other Perennials, is stunning with Ornamental Grasses, and mingling with sun-garden plants and shrubs. Holding their own against showier blooms like Roses and Hydrangea.
Tolerating harsh locations in the sun, handling poor soil, and periodic drought, making Ruby Star fantastic in the hell-strip along the road or sidewalk, in Rock Gardens, or in Xeric Gardens. Include them in your Fire-Wise landscaping plan! Use them as a cheerful mass planting. Space these herbaceous perennials 12 inches apart on center, measuring from the center of one to the center of the next.
Try them in large exterior containers, too. Use them as a single species, or add "Spillers" to the edges of your container to soften the look. Either as the main thriller or the vibrant part of a mixed planter on your porches and patios in the heat and sun!

#ProPlantTips for Care:
Ruby Star is a great sun-loving and drought-tolerant, and this herbaceous perennial is easy to grow in full sun and very well-drained soil. Provide regular moisture to new plants but once established, Echinacea are drought tolerant and low-water-usage plants. Mulch and regular fertilizer give them a boost.
If you've left your herbaceous perennials plantings to stand over the winter, just cut the stalks to an inch above ground level in early spring. Keep the flowers deadheaded to greatly increase the flowering. Coneflowers are almost maintenance-free, Echinacea is a native species that does well in most of the country with very little care, and these cultivars are just as tough.
