Tubular, red flowers sounds like Lonerica sempervirens, a
native plant that I see growing by the roadside in MD.
I took some pictures of red-flowered plants at the San Diego Botanical Gardens, several of them are apparently attractive to hummingbirds. While I was taking a nature walk in a chaparral area, I took a lot of pictures of plants. There's two that might be red-flowered wild salvias, probably attractive to hummingbirds. I saw a lot of hummingbirds on the walk, but they didn't stay still long
enough for me to get a picture.
There was some succulents flowering by the beach in La Jolla that honeybees were going crazy over. I have never seen so many happy
bees in one place. Might have been an ice plant? I didn't take my phone, being afraid to drop it in the
water...
