Rare Campanula relative from Bhutan, Nepal and Tibet. This has a perennial carrot-like root and in mid spring, the new growth emerges getting 12"-18" tall and tipped by pale blue bells with a darker blue base. We collect Codonopsis every time we see them in Asia because we love them. Musky foliage if bruised.
We haven't yet flowered this twining Campanula relative which we received as seed labeled Codonopisis - Royal Botanic Garden Edinburgh form. RBGE is Mecca for plantspeople with one of the finest collections of plants in the world. This is a herbaceous vine to 6' with likely blue flowers. Zone 6 at least.
One of the showiest in this genus of vining Bellflowers. Large purple-blue flowers with a dark ring - sometimes pure white - quickens our pulses in either expression. Recently reduced from species status, grey-wilsonii has been retained as a geographic race of the species convolvulacea based on larger leaves and flowers.
In the Bellflower Family, this is unusually non-vining as it makes a low clump of leaves from which long, stiff flower stems emerge to 18" tall. The flowers are held several per stem and while not large, overcome this size deficiency with exceptional detail. The small ivory bells are heavily netted in vivid maroon veins inside and out.
A herbaceous vining member of the Campanula (Bellflower) family from China. This has hirsute pale green leaves and loves to twine on thin twiggy stuff like a Exbury Azalea where it can display its pale greenish white bell flowers intricated traced with a brown netting on the outside.
