With its royal color, 'King Henry', (formerly called 'Prince Henry') delivers little mounds of beauty to your garden and containers. Violas love the cool weather of spring and fall, making them ideal for spring bulb cover, and for fall color after annuals are spent. In mild climates, they cheerfully bloom through the winter. Use the edible petals to garnish soft cheese or baked goods.
