(Aster) Aster ‘Henry I Purple’ is a vibrant, late-season bloomer that brings rich color to the garden when many other perennials are fading. This compact aster features masses of bright purple daisy-like flowers with golden yellow centers, blooming from late summer into fall. Its upright, bushy habit and dark green foliage provide a tidy backdrop for the long-lasting blooms.
Hardy in USDA zones 4-8, Henry I Purple grows best in full sun and well-drained soil. It reaches a height of 10-16 inches and spreads about 18 inches wide, making it a great choice for borders, native plantings, cottage gardens, or pollinator gardens. This aster is moderately drought tolerant once established and thrives in low-maintenance, sunny landscapes.
A magnet for bees, butterflies, and other pollinators, Henry I Purple adds valuable late-season nectar to the garden. It is also deer and rabbit resistant, helping protect it from unwanted nibblers. Whether planted in mass or tucked into mixed perennial beds, this aster delivers bold color, pollinator support, and reliable performance year after year.
