3) Campanula, Codonopsis, Edrianthus, and other Campanulaceae
Here's a thread for Campanula buffs!
What campanulas are you trying this year? Here's my line-up to date (those worth showing at this stage anyway). All pots are 2 1/4" square; all grown indoors under lights; all were easy, warm germinators.
1) C. argyrotricha NARGS - I'm not sure if this one is what it was said to be; doesn't seem to match Graham Nicholls' description in Dwarf Campanulas, so we shall see, of course!
I love the colour of Campanula saxifraga! I'm really looking forward to seeing how these young plants "bulk up" in their third year!
Unfortunately, I don't have any pix of this from last summer on this computer: perhaps I will transfer some here so I can post this...but this is the most abundant bluebell in the Altai which I was thrilled to see because I've grown Campanula sibirica for three decades at Denver Botanic Gardens, where it has spread everywhere (gently! not a weed). It is monocarpic, and thrives on rich, open soil where it can get quite large and sport dozens of flowers on and off all summer. We have had them pop up on occasion on sheer rock surfaces: they look all the more winsome this way.
I first got seed of Campanula trogerae from Jim and Jenny Archibald almost 20 years ago: it has thrived ever since then. In fact, I think my original plants are still growing in my first home garden to this day. They bloom from late June almost to August, in the very heart of the summer: surely among the largest flowered, and most crystalline blooms in the genus. Of course, instead of bell shaped these are this strange, starry shape reminiscent of Michauxia...come to think of it, Michauxia does grow thereabouts. Perhaps there was some ancient hanky panky with C.
