Sorry Rouge, I don't have 'Peaches Pick' stokesia, Mine is simply the common one but I do have several clumps of healthy plants thanks to winter sowing seeds. I look forward to the blooms every growing season. The plants are (so far) untroubled by pests.

I do whack my WS white balloon flowers each June to control height/reduce flopping but it doesn't diminish their prolific blooming come August.

I don't remember if I have Peachie's Pick or a different one at this time . I had Klaus Jelitto for years, which is a lighter color that what I have now. He was very nice for many years, then when I divided/moved, failed to bloom for many years running so I tossed him -- might have been too shady, not sure. Last year (or the year before?) I picked up a mid-blue variety at the nursery, and I have enjoyed it this year. Although it's not rangy or terribly unattractive, the foliage of Stokes aster is nothing to look at, so I would suggesting planting in an area where that won't bother you (i.e. it's not a "front of the border star" IMO).

Stokes aster needs sharp winter drainage, won't tolerate soggy winter soil. Requires no special care, though my experience leads me to believe it does better in full sun.

Rouge, I have two planted together and I really do enjoy this plant. The flowers are nice and big and vibrant in color and bloom for quite a long time. I also really like the white buds mixed with the purple flowers. I have them mixed with daylilies and they all bloom at the same time. Definitely a plant I'm glad I picked up and added to our cottage garden.

I had Stokesia Klaus Jelitto and S. Bluestone. Both did really well and bloomed for a long time midsummer for a few years and then the voles ate them one winter. To my pleasure, after a year's break, they have resprouted, so the critters must have missed a few roots. Mine are planted with yellow daylilies.

Oddly, this is a perennial which rarely appears in the UK - only found at nurseries rather than garden centres or box stores. I had one years ago - dunno what happened to it - suspect the usual lack of water(ing).

I think they need good drainage in the winter which they probably don't get in my clay soil

After getting feedback a few years ago here I am convinced I planted one or two and they did not survive the winter/spring. Knowing where I placed them I can see why ie clay with poor drainage :(.

Yes, I think that's it -- Honeysong Purple, I thinks that's the one I now have.

It's lower growing and darker purple. I really like it.
