These plants are among those used by hummingbirds in Texas:
Carolina Jessamine, Gelsemium sempervirens--this is often the first nectar plant for hummingbirds arriving here in the early spring, which makes it very important for them.
Turk's Cap, Malvaviscus drummondii
Flame Acanthus, Anisacanthus quadrifidus var. wrightii
Rose Pavonia, Pavonia lasiopetala
BTW, a book I have on hummingbirds of Texas, NM and Arizona lists other hummingbirds ID'd in the US:
Cinnamon
Green Violet-ear
Green-breasted Mango
Plain-capped Starthroat
I've been fortunate enough to spot the Green Violet-ear here...an amazing sight!
