Perennial plants I have found to attract hummingbirds are Trumpet Vine (Campsis x tagliabuana, I grow 'Madame Galen'), Butterfly Bush (Buddleia davidii), Honeysuckle (Lonicera, many varieties), and, I see them sticking their little beaksin my hanging baskets filled with Fuchsia. They seem to be attracted to bright, vibrant colors, especially red. Sweet fragranced flowers are also a draw.
