This would be a top ten in your personal garden, just like when a hybridizer registers the plants. If the plant was a northern bred dormant, it would probably never make my top ten. If it were a southern hybridized evergreen it would probably never make your top ten.
Naturally if I posted my top ten here and you posted your top ten, people would be able to see our zones and others also if they entered it.
Kent is looking for just such feedback, hoping everyone will chime in with suggestions.
