Lovely and flowering from may until when it gets to cold. I find them very good cutflowers too.

Aster x frikartii has an extraordinarily long season of bloom, from midsummer till fall. I wouldn't say that it covers itself in bloom, but it puts on a good show nonstop through its season (Boston Z6a). You can never have too many blue-violet flowers in the garden. But for me, it isn't really a fall bloomer.

I too have found it to be floppy and short-lived. My worst problem has been a tendency for the foliage on one or two stems (and eventually more) to begin blackening progressively down towards the ground until I prune the damage out. Looks like a fungal disease of some sort. It's happened in a variety of gardens and with plants from a variety of sources.

Wonderful plant. Bought two plants 10 years ago and have propagated them using softwood and hardwood cuttings. Easy to propagate, and they are the star of the autumn garden. Island bed display stopped traffic last year. I prune twice before July 1st (once in March, again in June) to keep them from flopping and am guaranteed a fine show by Halloween, which is what I want. The bloom starts in mid-October (because of the pruning) and last for weeks and weeks.

I took a division of this very fine perennial last Spring and it has increased four-fold since.
It blooms continuously here in my Southern California garden from late September until late November (or even longer).
The intense lavender-blue color is especially eye-catching in the slanting light of Fall afternoons.

How large do the flowers get?

Growing/flowering well with about 6 hrs. Texas sun. Starts blooming mid June here.

Excellent plant: lots of attractive lavender blue flowers: hardy: exceptional
for its long bloom time (at least six weeks): have never seen mildew on this aster: seems to be reasonably long lived (have five plants, in my garden, which are at least three years old): does need staking.

Love it! It is beautiful and a great addition for the garden and for BF's!

A magnate to insects at this back end time of the year and very welcome colour too.

Great fall-blooming color; prune in early summer to promote bushiness. Also make sure soil is on the poor side to prevent too much topgrowth. If - despite your efforts - the plants are floppy, stake them up to keep them looking their best during the blooming period.
