Named for the visionary 19th-century painter Rosa Bonheur, this dark pink petunia merges the romance of double blooms with the simplicity of single flowers on the same plant, creating layered depth in every planting. Its compact, well-branched habit and dual-flower form make it equally at home spilling from containers or anchoring garden beds. The soft contrasting centers of the single blooms add an unexpected tenderness to the otherwise saturated dark pink petals.
Rosa Bonheur petunias are grown for their ornamental flowers, which provide continuous color throughout the growing season in containers, raised beds, window boxes, and mixed borders. Their compact habit and prolific blooming make them especially valuable for creating bold focal points or massed displays where their dark pink doubles and single blooms create textural contrast.

Start seeds indoors 6-8 weeks before your last spring frost. Petunia seeds need light to germinate, so press them onto the soil surface without covering. Keep soil temperature around 75-80°F and maintain consistent moisture. Transplant seedlings to larger containers once they develop true leaves.
Transplant hardened-off seedlings outdoors after all danger of frost has passed and soil temperatures have warmed to at least 60-65°F. Space plants 6 inches apart. Water gently after transplanting and keep soil consistently moist for the first week to establish roots.
Rosa Bonheur's compact, well-branched growth habit requires minimal pruning. Pinch growing tips early in the season when seedlings reach 4-6 inches tall to encourage bushier development and more prolific branching. Deadheading spent flowers extends the bloom season, though this variety exhibits good self-cleaning tendencies.
