Gentiana paradoxa


Add to wishlist Remove from wishlist
A tough perennial from the southern Caucasus which has steadfastly refused to die despite some of our unintentional best efforts. This will, in time, make an impressive small clump of numerous upright stems to 12" or so which are tipped in late July to September with multiple blue flowers with pale whitish throats. This is happy in limestone conditions and is happy here in neutral to moderately acid. It wants to please. Does well in Denver Botanic Gardens as well as gardens in Sweden.
