I've never seen a hummingbird with them. I have some Salvia in the front yard with red and white flowers that almost always has hummingbirds visiting. The like the #$%@&!! Morning Glories on the hill too. (Morning Glories are invasive here)
I finally have a Red one just starting to bloom. I also have a pale yellow one that will be blooming soon. This red one, and the upcoming pale yellow one are all from seed I grew. It's a lesson in patience to grow these babies.
