Hummingbird Bush (Flame Acanthus): A Texas Native

It’s that time of year when hummingbirds start their migration through Texas. I’ve had a black chinned hummingbird visiting my feeder multiple times a day. While feeders are great, native nectar plants are even better.

Adding Hummingbird Bush (also called Flame Acanthus) is the perfect hummingbird magnet, especially for year-round residents and the fall migration.

Are you looking to add more native plants to your yard? Then I hope you’ll join me for my Native Backyard Challenge. It is a free four-week email course with the ultimate goal of having you incorporate two native plants in your yard. Sign up here and get all the details at the end of this post!

Where is Hummingbird Bush (Flame Acanthus) Native To?

This plant is a true Texan! This particular variety (Aniscanthus quadrificlus var. wrightii) is found in West and South Central Texas. However it is particularly associated with the Hill Country and the Edwards Plateau region around San Antonio where I live.

Flame Acanthus Attracts Hummingbirds

This plant is known for its profuse blooms of orange-red flowers. The flowers are trumpet shaped and upright, making them the perfect drinking vessel for hummingbirds and butterflies.

If you want a Hummingbird Bush covered in flowers from summer through fall, place it in full sun. It can grow ok in part sun, but will produce fewer blooms.

Unlike bees which can’t see the color red, hummingbirds are drawn to the bright red flowers.

5 Reasons to Grow Hummingbird Bush (Flame Acanthus)

1. It is profuse bloomer

It can be hard to find plants with long bloom periods, especially in the heat of the Texas summer. However, Flame Acanthus produces abundant blooms from mid summer until frost. Be sure to grow it in full sun where it will thrive.

2. It is heat and drought tolerant

If you’re looking for a low-maintenance plant this is the one for you. Hummingbird Bush loves the heat and requires very little watering once established.

It is even cold tolerant. In terms of hardiness zones, it will stay root hardy through Zone 7. Here in San Antonio, the plant even survived the mega freeze of February 2021!

It is a deciduous plant (it will lose its leaves during the winter). However if you cut back the dead branches by 2/3 in the spring it will regrow from its roots. This will help produce a denser, fuller shrub.

3. It is not picky about its location

As long as Hummingbird Bush has well drained soil, it is not picky about the type of soil. It is also not super picky about sun conditions. It prefers full sun, but can grow in dappled to part sun as well. However, I would not recommend it for full shade areas.

4. It is a butterfly host plant

In addition to feeding butterflies with its nectar, it also feeds butterfly’s caterpillars as a host plant. Anytime I can add a butterfly or moth host plant to my garden it is a win. Read more about why having host plants in our yard is so important for the ecosystem.

5. It is easy to grow in containers

I love incorporating native plants into my container pots on my patio along with annuals. Flame Acanthus grows to about 3-4″ tall and wide, making it a good candidate for a large pot.

Make a Hummingbird Garden

Hummingbirds migrate through Texas every spring and fall, and some stay year-round. Hummingbird bush will be in full bloom for their fall migration.

Pair this plant with other Texas natives such as Turk’s Cap and Autumn Sage to create a garden that attracts hummingbirds. These perennial shrubs also have red tubular shaped flowers that hummingbirds and butterflies can’t resist.

If you include these plants and add a hummingbird feeder (this is the one I use), you’ll have a hummer paradise in your yard!

Names for Hummingbird Bush

Scientific Name

Aniscanthus quadrificlus var. wrightii is the scientifc (Latin) name for the Hummingbird Bush I am referring to. That is certainly a mouthful, and I’m not sure I can even pronounce it correctly! However, that is the name you’ll want to look for on the plant label at the nursery to ensure you’re getting the native plant.

It is especially important because there are several other non-native plants with the common name Hummingbird Bush such as these. Here are their scientific names:

  • Dicliptera suberecta
  • Hamelia patens
  • Grevillea thelemanniana

Common Names

Each plant variety has only one scientific name but can have several common names. In addition to Hummingbird Bush, one of the most common names for Aniscanthus quadrificlus var. wrightii is Flame Acanthus.

I like to use Hummingbird Bush because I think it will encourage more people to plant it! Who doesn’t like hummingbirds?!

How Do You Prune Hummingbird Bush?

Maintaining hummingbird bush is easy. Just cut back by about 2/3 in February. You are removing the dead branches to encourage new growth from the base and create a more fuller, rounder plant. Leaving the dead foliage on the plant through winter helps provide habitat for insects and birds.

  1. I had a very small fame acanthus in a pot along with some cannas—actually I think it may have planted itself there—anyway, it is coming back after the freeze!! I am so excited because when it gets a bit bigger, I am going to plant it in the ground in my new pollinator garden!!!

    1. How exciting Martha! I planted my first flame acanthus in the ground this spring after admiring it at the AAMN Demo Garden. It looks very healthy and I’m excited to see it in bloom!
