Sophistica® Blackberry Petunia

Sophistica® Blackberry is a grandiflora petunia with shimmering black flowers and reddish-purple undertones; its compact, mounded habit suits containers. PanAmerican Seed lists this selection for full sun. The official plant information gives a height of 10–15 inches and a spread of 10–12 inches. The Sophistica collection is described as abundant grandiflora blooms, with timing matched across the group for consistent crop scheduling. Petunias generally perform best with at least five to six hours of sunlight and soil that drains well. Water thoroughly when needed; hanging baskets and other containers may dry faster than garden beds. Remove faded flowers when practical to prolong blooming and keep container displays tidy. The [PanAmerican Seed product page](https://www.panamseed.com/Products/048605893000591/petunia-sophistica-blackberry/) identifies this exact named selection and provides its growing details.
