purple dome aster

I just returned from the Minnesota Landscape Arboretum. All of their purple dome asters are blooming and gorgeous, and 12 - 15 inches tall. What am I doing wrong? mine grow to be 40 inches and flop in the rain. I've tried the cut-back routine, but they grow just as tall. About ready to give up on them, but the beauty I saw today gives me pause.

I have two Purple Dome asters. One stays short and the other gets very tall. Perhaps one was mislabeled or some nursery grown plants were not stable and reverted to a taller parent. If you want a shorter aster try a different Purple Dome plant.

RE: purple dome aster

I have one that I received at a MN GW plant swap about 6 or so years ago. It was passed up by everyone there, so I rescued it. It was labeld Purple Dome Aster and I beleive it is such. Since it had been passed up by everyone I was leary of it (hadn't looked up anything on it) so I planted in the gardens at the lake. BIG mistake since it has grown into a 2ft bush that blooms beautifully and I only get to enjoy it on the weekends. If I would have known it was going to be such a nice plant I would have planted at home to enjoy nightly in the fall. It's vey well behaved, has not seeded all over the place like other Asters.....


RE: purple dome aster

My Purple Dome gets about 13-14 inches and is covered wi th blooms every fall. My problem is that the deer love it and just eat all the blooms off, So I start spraying it as soon as buds appear. Mine are just in good garden soil,
