Acanthus mollis 'Whitewater'

Plant details

Acanthus mollis bears enormous, deeply lobed leaves, from which tall flower spikes clothed in white flowers, each with a hood-like purple bract, emerge in late summer. The flowers can be used in fresh and dried arrangements.

Acanthus mollis ‘Whitewater’ has dark green leaves heavily splashed with white, with bold margins. Its flowers are pink and cream-white. It's perfect for growing in a mixed herbaceous border, particularly among bold colours, and makes striking architectural presence.

planted up some seeds of this earlier this year [about May 09]. No sign of any growing shoots. Are they slow germinators?


I planted some seeds of this in early April, i bought the seeds from Italy and they have just germinated so I'm really pleased and excited. I hope to have some strong healthy plants from them ready for flowering next year.


My acanthus plant 3 years old seed from Greece. Had fantastic green leaves,now they are covered in like a grey powder. Anyone tell me why and what to do. Did not have this trouble last year.

Its a pretty plant but very invasive! once you plant it and its established its not going anywhere else apart from up.
