Viola Tricolor (Heartsease) is a charming and delicate flowering annual prized for its cheerful, multi-toned blooms that often feature a mix of purple, yellow, and white. Its dainty flowers and low, spreading growth habit make it ideal for adding soft colour to garden beds, borders, rockeries, and containers. Blooming generously through cooler seasons, Heartsease brings long-lasting seasonal interest and a cottage-garden feel to any planting space while also attracting bees and other beneficial pollinators.
Easy to grow and versatile, Heartsease thrives in full sun to part shade and performs best in well-drained soil with regular moisture. Its compact size makes it perfect for edging pathways, filling gaps in mixed plantings, or creating colourful displays in pots and hanging baskets. Low maintenance and quick to establish, Viola Tricolor is an excellent choice for gardeners seeking reliable colour, ornamental charm, and a soft, naturalistic look in the landscape.
