I love my anisacanthus! I took some new plants from my grandmother's garden last fall. I wasn't sure they would make it after our freezes in the winter but within the last week they've gone crazy. I can't wait for them to bloom to bring out the hummingbirds.

This plant isn't showy, but bees, hummingbirds and butterflies love it. Give it plenty of space to spread out...I put mine in a huge (20") pot in the spring. Since then, the plant has tripled in size, and the roots fill the pot. I'm going to transplant it into a whiskey barrel. Cuttings I took in the Spring are rootbound in qt containers; those will go into the ground

It spread to at least twice the original planting area by 100s of seedlings. I dug it up and threw it out. It seemed invasive to me. Flowers are very small and not very interesting.

Native desert shrub to Southern New Mexico, Central Southwestern Texas, and Arizona.

Positive BajaBlue On Mar 15, 2010, BajaBlue from Rancho Santa Rita, TX (Zone 8a) wrote:

Hummingbird Bush is native of Mexico and Texas is a delight for hummingbirds. Its a small, spreading shrub with orangish-red tubular
flowers from mid-July or August ( earlier in the southern states,) until frost.

Hummingbird Bush is suited to a wide variety of soils, including poor soils, and is drought and heat tolerant.

I purchased three little ones last spring so now in their second year they are 3' X 3'. Hummingbirds do love them. They get watered when it rains.

Positive SisterClay On Mar 9, 2006, SisterClay from Hurst, TX (Zone 7b) wrote:

I love this plant! I planted it in the fall from a little 4 inch pot. When it grew back in the spring, it was huge. It grew to about a 6 foot spread by 3 feet tall. I was also pleasently suprised to look out my window one day to see a hummingbird feeding on it.

It did produce at least 1 new plant the following fall which I dug up and planted in another part of the garden.

Positive frostweed On Aug 24, 2004, frostweed from Josephine, Arlington, TX (Zone 8a) wrote:

I love this plant, and so do the hummingbirds. It blooms all summer even in
part shade, and can take the heat with no problem.
I do not have any trouble with it overpopulating and I would not mind having many of them. They are beautiful and easy to root, blooming through the hottest part of summer.
This plant is endemic to Texas and one of my favorite shrubs.

Every garden should have one Flame acanthus, and only one! Seedlings pop up everywhere in the yard propogated by birds, wind, etc. Hummingbird magnet. Blooms summer through first frost. I never, ever water mine. Do not plant with intentions of containing it to one area.
