Firespike (Odontonema strictum) is really giving us a show right now.
Migrating hummingbirds and fall butterflies love the nectar Firespike provides. Usually blooming from late summer until that first frost, Firespike gives a good show at a time when the garden looks a bit bedraggled.
You will also love the rich green very tropical foliage all summer too. Requirements for this plant are simple: full sun to part shade. It will even grow in quite a lot of shade, but will not bloom as much.
It loves sun, heat, and humidity (which all Texans can readily provide) and good soil. Taking regular water but surviving much less, Firespike is an easy plant.
Once it freezes, cut it to the ground and mulch with pine straw to protect its roots in winter. Give it plenty of room to grow, because it will get 3- to 4-foot fall tall and 2- to 3-foot wide.
