Blackberry Ripple Hollyhock

Alcea rosea ‘Blackberry Ripple’ is a tall hollyhock selection with ruffled double and semi-double flowers in contrasting blackcurrant and white tones. Its upright flower spikes suit the back of sunny borders, cottage gardens and wall-side plantings, where the bicolor blooms can be seen above the lower foliage. ## Cultivar and season [Thompson & Morgan Wholesale](https://www.tandmwholesale.com/seedsbycategory/AlceaBlackberryRipple) lists the named cultivar as a seed product and describes the blackcurrant-and-white flower mix; its page gives flowering from June to September. The [Swift 2025–26 wholesale catalog](https://www.carlinsales.com/media/1965/swift_catalog-20252026web.pdf) describes ruffled double and semi-double flowers and lists a 5–6-foot height, 18–24-inch spacing and zones 3–9. Catalog descriptions differ slightly on the stated height, so treat it as an approximate garden range rather than a fixed mature measurement. ## Siting Grow in full sun and well-drained, moderately fertile soil, following the general guidance for Alcea rosea. Leave air around the leaves and allow for the tall flowering stems. Like other hollyhocks, this cultivar may be susceptible to rust, especially where summer weather is wet or planting is crowded. ## Maintenance Water new plants while establishing and during extended dry periods, directing water to the soil rather than wetting foliage. Inspect leaves for rust and remove affected material promptly; clear diseased debris from the bed. After flowering, cut back or remove spent stems if you want to reduce reseeding, or leave some to mature when volunteer seedlings are welcome.
