Unless you have your heart set on roses, you might want to plant one of the orange, red or yellow varieties of trumpet vine or honeysuckle.
The hummingbirds will buzz these types of flowers from dawn 'till dusk, and you never have to worry about messing with a feeder unless you want too!
I have a strange phenomena, or so it seems. My pair of Red-wing Blackbirds went to 3 a few days ago. One, I'm assuming the male, has stunning feathers, and he is always fluffing them up to show them off. The other 2 I'm guessing are females. Their wings aren't as brightly colored and they don't exhibit any of the puffing and preening behaviors. It just seems odd to see them as a threesome. I've not seen any trace of another male bird.
