Colibri, Blake, jayjay, Doobieous, Jeff Lichtman, picunurse, you all are the best. If you ever come through Houston, the beers are on me. Now, on to the next batch.
#1. Just some happy yellow flowers that the bees seemed to like.
#1 looks like it could be some sort of Composite. Realizing, of course, that that’s sort of like saying of an insect, “It could be a beetle.”
#2 LOOKS like a plumeria flower, kind of. Growth habit would be helpful here. Maybe a plumbago, but I think they’re mostly bluer.
#3 is Anthurium (Flamingo Flower). Not sure of the species. And it’s actually none of the above…the red part’s a spathe. The yellow club is a spadix, and it’s actually the inflorescence.
#4 I don’t know. WAG judging from what the flower looks like, some kind of columnea or cuphea (two totally different genera in totally different families, I think, but the flowers of the cultivated varieties both look a little like this).
#1 is definitely some kind of Composite, but yellow comps are popularly known by botanists as DYCs, Damn Yellow Comps, since there are so many of them
#2 I agree with Plumbago
#3 I agree with Anthurium, specifically a cultivar of Anthurium andreanum
#4 It doesn’t look like Cypress vine to me, but I don’t know what it is.
#5 I agree with Hydrangea
#6 is some kind of Heliconia (some of which are called lobster-claw flowers), but since there are a lot of similar species and cultivars I won’t try to be more specific. It’s not native to Hawaii, but to tropical America
