The plant has been a delightful performer, potted and in a mostly shaded area of my front porch. This is its third year in this location, and the plant is larger and more vigorous each year. I have not moved the plant during either of its winters here, and it has survived just fine, although I will mention that both of these winters have been on the mild side.

The variegation is very attractive, as are the tall flower bracts. Some of the leaves are pure white.

I have attempted to grow this plant several times over the past few years. It has been my experience that it struggles to come back each year and gradually gets smaller and then eventually
dies off. I have had luck with other acanthus species but this one is more difficult I have found.

Has anyone had this plant revert back to a non variegated form? I have had that happen to a couple of different variegated forms of other plants, and just wondering about this one.

Acanthus 'Whitewater'
I was advised today (3-15-12) by an online retail nursery that there is no significant difference between A. 'Tasmanian Angel' and A. 'Whitewater'. I have 'Tasmanian Angel' in my garden and would like to know if indeed there is difference worth the money.

Bred with Acanthus Summer Beauty for vigor, hardiness, heat and humidity tolerence. Prefers deep fertile, moist, well drained soil. Good variegated evergreen foliage. Variegation may not appear on young plants. Good for difficult spots.
