Royal purple - Campanula saxifraga

Another with rich purple colour... Campanula collina.

Lori, I am always looking for blue flowers to plant in my gardens (Yellow is the commonest color here). Bluebells are among the best I can grow and now you have opened my eyes to two more species I have to search for!

We have C. saxifraga in the BG, but nothing as blue as yours!  That is stunning.  We don't have collina.  Our deepest blue is the so-called C. tatrae...may be just a variety of rotundifolia but still, very deep compared to our other rotundifolia.

Yes, I've seen colour variations to both C. saxifraga and C. collina.  The C. saxifraga, grown a couple of years ago from seedex seed, compare favourably in colour to the gorgeous ones shown in Holubec's Caucasus book (which, BTW, is being advertised at a terrific price on the main forum site)! 

Great plants, Lori!

I also bought The Caucusus and its Flowers.  I've hardly had chance to look at it, but even if it were only a picture book (not), the price is fantastic!
