There are a few that have been huge successes. Among my favorites are Snow Fountains Guara (above) and Luna Blush Hibiscus.
Daylilies have done well, too. Buddhist Flame and Lavender Deal are included in these shots.
But not everything in the garden came with a tag. This beautiful climbing rose has been passed from garden to garden. My daughter-in-law's mother first started it from a cutting. It traveled with her when she moved and was shared with her daughter when her daughter and my son bought their first house. They blessed me with a cutting a couple of years ago.
