'Purple Gem'
Dahlia
Dahlia 'Purple Gem' is a semi-cactus variety known for its deep violet-purple blooms with long, pointed petals that create a dynamic, spiky effect. The flowers, typically around 5 inches in diameter, shimmer in the light, adding a dramatic presence to garden beds and floral arrangements. This dahlia reaches a height of approximately 36 inches with a spread of 18 to 24 inches, forming a bushy, upright habit. Blooming from mid-summer until frost, it thrives in full sun and well-drained soil, making it a reliable choice for borders, containers, and cutting gardens. It attracts pollinators such as bees and butterflies while offering some resistance to deer and rabbits. Hardy in USDA zones 8 to 11.
