Looks like Tecomaria capensis, Cape Honeysuckle. They range from yellow to red. Look at the photos on this page and see what you think Cape Honeysuckle (Tecoma capensis)
I have the Red Firespike growing in my yard here in Florida and I have seen Ruby-throated Hummingbirds visiting the flowers on occasion but the plant they seem to prefer much more is Odontonema tubaeforme (synonym Odontonema strictum). Firespike (Odontonema tubaeforme) which grows in zones 9 and 10, including California. https://www.californiagardens....
This California Native Plant Society webpage should offer help; it has a list of California Native Plants that attract Hummingbirds: https://www.cnps-scv.org/index...
~ I'm an old gal who still loves playing in the dirt!
~ Playing in the dirt is my therapy ... and I'm in therapy a lot!
Anything Salvia or Agastache is a MAGNET!
All the Tecomas are good.
Fuchsias for shady places.
Calliandra
Callistemon and Melaleuca
Million Bells and Petunias in hanging baskets are good.
Aloes if you don't want to water.
I agree, that's definitely Tecoma capensis.
