"Silverado note" both Tom & I have colder climates. Immortality takes a season or 2 to get going. but once started does very well. Before the Storm one year survived under 4 inches of ice. American Maid is not colorful, but very tough in a colder climate. Stairway to Heaven does very well in our climate. Pink Attraction can rebloom in New England. Vanity is a good grower, but the foliage is ratty. There, I have hit 12. Not a lot of color variation , but good growers for a New England climate. Right now our only TB hybridizer is Stephie Markham who does mainly MTBs. Going over 12, Ink Patterns does well here. That gives a plicata.
