Did you know hummingbirds tend to like the smaller flowered uprights more than the big doubled flowered cultivars? They seem to have more nectar. The flowers are usually more abundant. And I think the nectar is just easier to get to on the smaller non-double blossoms. This here is 'Margery Blake' and she's definately one of my hummingbirds favorites. I've been told that is also has to do with how much closer these cultivars are to the original species, and that hummingbirds seem to prefer species over the hybridized cultivars.
