Adding vibrant color to the late summer garden, Aster novi-belgii ‘Royal Ruby’ (New York Aster) features masses of semi-double, rich mulberry-red flowers with bright golden yellow discs. Borne on slender, branched stems bearing lance-shaped, dark green leaves, they bloom for weeks from late summer to early fall and enliven any sunny corner of the garden. Native to North America, this eye-catching dwarf Aster is easy to grow, long-lived, brings cheerful fall color, and is a great source of nectar for butterflies. Perfect for small gardens or containers!

  • Typically grows with an upright, bushy habit, up to 40 in. tall (100 cm) and 20 in. wide (50 cm). It may need staking. Deer and rabbit resistant!
  • Thrives in full sun or partial shade, in average, medium moisture, well-drained soils. Moist, rich soils are preferred. Provide good air circulation to avoid foliage diseases such as powdery mildew. Drought, salt, and wet soil tolerant.

Aster novi-belgii, commonly known as New York Aster, belongs to the Asteraceae family, including yarrows, chrysanthemums, and sunflowers. The Genus Aster contains over 600 species and thousands of hybrid varieties, providing a wide choice to pick from, as they all vary in habit, height, flower color, leaf shape, and growing conditions. The flowers of New York Asters are always held in sprays rather than individually and provide an outstanding late-season show.
