Primula japonica 'Miller's Crimson', commonly known as Miller's Crimson Japanese Primrose, is a rosette-forming perennial with tall spikes of deep crimson-red flowers that bloom from late spring to early summer. Thriving in partial shade and moist, well-drained soil, this variety is perfect for woodland gardens, borders, and shaded areas. The rich, red blooms of Miller's Crimson attract pollinators and provide a bold, dramatic color in the garden.
