About this plant
Acanthus mollis 'Whitewater' is a bold, variegated selection of the classic bear's breeches, offering a mix of deep green and creamy white marbled foliage. This cultivar is a sport of Acanthus 'Summer Beauty' and retains the dramatic, deeply lobed leaves characteristic of the species while adding an extra layer of visual interest with its variegation. It makes an excellent choice for adding texture and brightness to shaded or partially sunny garden spaces.
During late spring to summer, 'Whitewater' produces tall flower spikes adorned with two-toned blooms in soft pink and white, each framed by spiny bracts. These vertical floral displays rise above the foliage, adding structure and elegance to the plant's overall appearance. The combination of variegated leaves and architectural flowers makes it a standout in mixed borders, where it provides a dynamic focal point throughout the growing season.
