The variety’s compact, symmetrical form also makes it a favorite for mass plantings in public gardens and landscapes — offering bold color with minimal care.

🌺 4. Perfect for Pollinators and Summer Displays

Vinca blooms attract butterflies, bees, and pollinators while being deer and rabbit resistant. The result? A beautiful, eco-friendly display that supports pollinator life and stays lush through the hottest months.
