Notes

Flame Acanthus is covered with gorgeous red flowers during the hottest parts of the summer, and continuing into the fall. Hummingbirds absolutely love it. One of our toughest plants, highly drought tolerant once established.

Left unpruned, I’ve seen these grow as wide as 6 ft or more. Cut back to 1/3 in late winter, before spring growth emerges. If it gets unwieldy because of abundant spring rains, you can cut back the leggy bits in June.

Plant this where it catches the rays of the morning or evening sun, and it will look like the whole bush is on fire, living up to its name.

We have Flame Acanthus to spare! These seed out easily and produce plenty of volunteers. Very easy to transplant.
