Hosta ‘Krossa Regal’
Hosta ‘Krossa Regal’ is one of the classics, and it is an impressive sight with its large, vase-shaped mound. This hosta has thick, naturally slug-resistant, frosty blue leaves that become a slightly deeper blue as the season progresses. In my gardens, I use these upright hostas as a background for smaller hostas. Unfortunately my largest Krossa Regal had grown to be so huge, we needed to move it to a larger spot, and it was just too big to be moved intact, so I reluctantly divided it for the first time last year. Krossa Regal is sterile and does not produce seed pods, so I always cut the flowers off, leaving a few inches of scape, as soon as it finishes blooming. Like a few other hostas, Krossa Regal will sometimes turn an orangy-gold color in the fall, although this has never happened in my gardens. I think perhaps the summer temperatures are too cool for that to happen to hostas growing here?

I just purchased an un-named hosta. It is vase-shaped but that seems to be the only characteristic it shares with H. Krossa Regal. Can you tell me the names of (apparantly) fast growing, vase shaped hostas. I am assuming there are not too many cultivars with the vase-shaped appearance. Thank you. Jane Allensworth
