I bought a Tecoma x 'Sparky', more for the hummingbirds than for me. I'm not excited about the flower color--the yellow is strong and clear but the burgundy/bronzy exterior of the flower seems muddy.
It coordinates with Kalanchoe orgyalis, and with the Gaillardia I can't get rid of.
'Sparky' is named after the Arizona State University mascot; the flower colors are (roughly) the school's colors, yellow and burgundy, and the plant was hybridized by an ASU faculty member, George Hull. Tecoma is native to xeric climates, including Arizona, and needs little water once established.
'Sparky' has at least two virtues worth noting: the growth habit is somewhat more compact than T. stans, with an estimated size of 5-6' tall and 3'-5' wide, and it is almost (or completely) sterile, so it's not going to be reseeding aggresively, if at all, and won't need deadheading to encourage repeat blooming, which is said to be lavish. If the humingbirds like it--well, I like hummingbirds.
Speaking of hummingbirds, they have been mobbing the feeder lately. I set up the tripod and new remote shutter control. Beloved sat on the patio to enjoy a beautiful autumn day and snap some photos.
I hope as the Tecoma grows and estabishes, we'll be getting photos of hummers enjoying the flowers.
