Aster Purple DomeThe deep purple daisy-like flowers with bright gold centers make ‘Purple Dome’ a standout in the garden. Blooming at a time when other plants are fading, it gives a fresh and new look to the garden. The bushy, compact plants are attractive throughout the growing season and are usually completely covered with small attractive flowers from mid August through September. Because it is only 18- 24” high it doesn’t flop or need staking, unlike many other New England asters, and can be used at the front of the border or as an edger. It is easy to grow in any decent garden soil, attracts butterflies and birds, and is a good cut flower.

  1. They are a lovely colour. My attempts at growing Asters have usually failed because of mildew. My light dry soil doesn’t help. either. Perhaps there are more resistant varieties around now.

    1. Mildew is a bummer! My phlox seem to suffer quite a bit even though I use the resistant varieties. My zinnias and tall asters do also. For some reason my small or compact cultivars (‘Purple Dome’, Alma Potschke’) do not. My tall asters are lanky and I don’t care for them much anyway.
