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.
