The Dahlia ‘White Aster’ produces masses of stunning, pompom-like, ivory-white flowers, sat atop strong, sturdy stems. Eye-catching for their full and frilly qualities, these plants grow spectacularly tall, adding to their captivating aesthetic. 

Classed as ‘Decorative Dahlias’, these tender perennials feature broad, flat-tipped petals with an occasional wavy texture. The flowers themselves are normally large, with petals that are either formally and evenly placed around the stem, or informally, where the petals sometimes bear a slight roll at the tips.

  • Flowers: July - October
  • Hardy
  • Fertile, moist, well-drained soil
  • South, East or West aspect

Feed weekly, and water well in hot weather. The tall flower stems will require staking and tying in, but this is well worth the trouble for the magnificent display that they produce. Larger flowers can be obtained by pinching out the side buds and just keeping the terminal buds. Deadhead spent flowers to encourage more buds. Lift the tubers once the foliage has died back and store in a frost-free location in moist sand or compost.
