Here in Montana the plant grows like a weed, invading the lawn and spreading furiously. No way to get rid of it. Looks nice for a while, but crowds out the grass.

I grew this from seed and it is blooming its little heart out! It is doing really well for me, especially considering it is under a greedy maple tree.

I had one of these plants but it died for an unknown reason last year at flowering time..........It just dried up and died.
It had a nice large purple flower on it when I bought though.
My variety was called 'Goliath'.

Alpine asters are great for the rockery or the front of the border. The flowers are quite large compared to the small size of the plants. I started mine from seed and they bloomed the second year after sowing. They're very easy to care for and a well behaved garden plant.
