"Premium hosta varieties"
The following is from a hosta description in the Walters catalogue. Is anyone familiar with this designation? Is there an actual list?
This premium hosta variety is part of a group of the finest hostas available today. Members of this collection were evaluated and selected by a group of specialty hosta growers in zones 4-7, who together have a combined total of over 150 years of hosta growing experience. To be considered a premium hosta, plants must perform superbly in all four zones (4-7). They must also exhibit exemplary garden presence and performance, have a long season of appeal in the landscape, have leaves of good substance, and demonstrate a greater resistance to common garden pests.
