Botanical denomination: Acanthus spp.

Variety designation: ‘Whitewater’. Parentage: Acanthusx‘Summer Beauty’xAcanthus mollis TASMANIAN ANGEL®.

The new variety has been reproduced only by asexual propagation (division and micropropagation), using the nor mal organ method where tip and lateral buds are cultured. Each of the progeny exhibits identical characteristics to the

original plant. Asexual propagation by division and micro


propagation as done in Canby, Oreg., shows that the forego

The present invention relates to a new and distinct cultivar ofA canthus, given the name, ‘Whitewater’ . Acanthus is in the

family Acanthaceae. This new variety originated from a

planned cross between Acanthusx‘Summer Beauty’ (an unpatented plant) as the seed parent and Acanthus mollis TASMANIAN ANGEL® (an unpatented plant) as the pollen parent. Compared to the seed parent, Acanthusx‘Summer Beauty’, the new cultivar has variegated leaves and pink 15 tinted ?owers and bracts rather than unvariegated leaves and white ?owers with purple bracts. Compared to the pollen parent, Acanthus mollis TASMANIAN ANGEL® the new
