Nursery contributed plant descriptions

It's back; we finally propagated more of this little shrubby blue borage. These are from Mojmir's collections from limestone rocks at 1300m near Biokovo Croatia, its hardy and features intensely blue flowers on 10-20cm helicoid cymes over silky pubescent dark green shrublets that can reach 1.5m wide by 45cm high in it's native habitat; not too difficult but hates being overwatered, you've been warned.
