H. 'Stained Glass'
The annual crapshoot that is the purchase of bare root bagged Hosta from Costco was supposed to give us 4 'Frozen Margarita'. As they started to unfurl their leaves it became evident that yet again we have another example of contents not matching the label. By summer's end it's pretty well clear to me that what was in the bag is 'Stained Glass'. When we get them in bloom next year it should be easy to confirm that with the scent of the flowers.
This fragrant flowered cultivar was the Hosta of the Year -HOTY- for 2006, as selected by the American Hosta Growers Association. To receive this honor the plant must be readily available in the nursery trade for retail distribution and meet the criteria for pricing, which is around $15 in the year of selection.
