I could easily divide the following: Solidago rigida (Stiff-leaved Goldenrod) See link below. This is a big one - 4-5 feet tall. I loved it last summer. Solidago Baby Gold - Blooms early summer and will continue into fall if cut back. Grows about 2 feet tall. Aster dumosus 'Woods Pink' Mum Clara Curtis Please note: It has been a cold spring in Minnesota and plants are barely poking out of the ground. Don't expect a lot of foliage on these plants, but they will be nice divisions with great roots. I'm mainly looking for other fall asters including natives, maybe goldenrod, maybe mums.

I had that one identified on this site a week or so ago. It looks like Classic Canada Goldenrod like you thought. http://forums2.gardenweb.com/forums/load/namegal/msg09215028601.html Here is a link that might be useful: Forum answer

Thanks much, Wanto. Going to look at your link now. Indeed, a very fertile area for exploration! Where I'm at, New England aster rules. And that's surely not a bad thing! Plus, there are color phases present within most stands, so you've got the basic blueish-purple, but then there will be deep coral pink and even some more sky blue (Not the aster species of that name) all mixed in together. Really amazing. Throow in the various wild goldenrods,and the frost asters that are usually blooming in that same late summer/fall timeframe, and you've really got something-all without a single human intervention. Of course, where we're purposely establishing prairie plantings-in my case, around stormwater ponds, etc.-we do go with a much more diverse mix. But in truth, I like just what happens around here on its own just as well. Up north at my tree farm there is a slightly different aster mix going on. I'm still working to ID what we've got growing there. At first, I thought smooth aster, then sky blue, but I haven't quite sussed it out yet. Simply put, I need to take my books with me next fall! Thanks again for the nice research idea! +oM

I can't say what would happen in your zone, but in my zone if I cut them back now they wouldn't bloom at all. There wouldn't be time before frost. Cutting plants back doesn't assure blooming. It does assure shorter, bushier plants.
