Aster
Asters are perennials known for their daisy-like flowers that bloom late in the year, providing a significant source of color in gardens when many other flowers have faded. They are native to various regions across the Northern Hemisphere, including North America, Europe, and Asia.
Size: The growth habit of asters can vary widely, with species ranging from compact, mounding forms to upright, spreading varieties. Their size can differ dramatically, with some dwarf varieties only reaching a few inches tall and others, like the tall New England aster, growing up to 6 feet (1.8 meters).
Flowers: Aster flowers are renowned for their vibrant hues of purple, blue, pink, red, and white, typically with yellow centers. These blossoms, which bloom from late summer into fall, are a late-season source of nectar for butterflies and bees, making asters an excellent plant for supporting pollinators.
Hardiness: Asters are hardy in USDA zones 3-8, though this can vary slightly depending on the species.
Uses: They are used in various garden settings, including borders, cottage gardens, wildflower meadows, and butterfly gardens. Asters also make excellent cut flowers.
Deer: While asters are generally not toxic to humans or pets, they’re not usually a favorite of deer, which tend to avoid them due to their slightly bitter taste. However, rabbits might nibble on them.
A key fact about asters is their importance in the ecosystem, providing late-season food for pollinators. Additionally, their ability to bloom when many other flowers have stopped makes them a crucial part of a succession planting strategy, ensuring that your garden remains vibrant and colorful well into the fall.
