H. 'Frozen Margarita'
The annual crapshoot that is the purchase of bare root bagged Hosta from Costco was supposed to give us 4 of this variety. As they started to unfurl their leaves it became evident that yet again we have another example of contents not matching the label. Best guess at this early point is 'Fragrant Dream', but we'll have to wait until we see, and hopefully smell, the flowers later this summer.
It would appear by late summer 2009 that what was actually in the bag were 4 crowns of 'Stained Glass', so at least they're another fragrant flowered variety we did not have as yet.
