Flame Acanthus is a most wonderful and useful plant.

#1 Drought tolerance, I have never seen this plants wilt even in the hottest days, and and it can go without water for at least two weeks and not suffer one bit.

#2 Nectar for hummingbirds and butterflies, if you have this plant and they are in your area they will visit it regularly, guaranteed.

#3 Long lasting beauty and adaptability, this plant will bloom in full sun and partial shade for a very long period of time, until frost causes it to go dormant.

I truly couldn't do without this plant and I highly recommend it.
