Sky Blue Aster: A Beautiful and Easy-to-Grow Native Plant
Introduction
Sky Blue Aster, also known as Azure Aster, is a beautiful North American native plant that produces brilliant blue flowers from late summer until the first frost. It’s a popular choice for gardens because it’s easy to grow and attracts pollinators.
Sky Blue Aster Information
The Sky Blue Aster was first identified by botanist John L. Riddell in 1835 along the Olentangy River in Ohio. Its scientific name, Symphyotrichum oolentangiense, comes from Greek words meaning “junction” and “hair,” and pays homage to the river where it was discovered.
Sky Blue Aster is a sun-loving wildflower that grows best in prairies and meadows. It’s a relatively short plant, typically reaching a height of 1-2 feet. The leaves are lance-shaped and the flowers are daisy-like, with bright blue petals and yellow centers.
How to Grow Sky Blue Asters
Sky Blue Asters are easy to grow in USDA plant hardiness zones 3 through 9. They can be grown from seeds or starter plants. If you’re starting from seeds, sow them indoors in late winter or early spring. Transplant the seedlings outdoors after the last frost.
Sky Blue Asters prefer full sunlight but can tolerate partial shade. They need well-drained soil, as they may rot in soggy conditions. Water them regularly, especially during the first growing season. Once established, they are relatively drought-tolerant.
Sky Blue Aster Care
Sky Blue Asters are generally low-maintenance plants. However, they can be susceptible to powdery mildew, a fungal disease that causes a white powdery substance to form on the leaves. To prevent powdery mildew, plant your Sky Blue Asters in a location with good air circulation.
Another potential problem is self-seeding. Sky Blue Asters can spread aggressively, so it’s important to deadhead the flowers regularly to prevent them from taking over your garden.
Sky Blue Aster Benefits
Sky Blue Asters are a beautiful and beneficial addition to any garden. They attract pollinators, such as butterflies and bees, and provide winter sustenance to songbirds. They are also a good choice for erosion control.
Conclusion
Sky Blue Aster is a beautiful and easy-to-grow native plant that is perfect for gardens of all sizes. With its bright blue flowers and attractive foliage, it’s sure to add beauty and interest to your landscape.
