A rare color for Dahlias, Blue Boy is in-ground hardy throughout USDA hardiness zones 9 to 11. Northern growers, and gardeners in all growing zones, can enjoy these blooms as seasonal accents and annuals, or dig the tubers up in the fall and store them as you would Canna Lily or Elephant Ear Bulbs.

#ProPlantTips for Care:
Dahlia blooms all summer without fading in full to partial shade and prefers a wide range of soil types, including clay, and acidic conditions, as long as it's well-drained! Soak the tubers for a few hours before planting and plant them with their fingers spread out gently and pointing downwards. To ensure even moisture, place mulch around the base of the plant. Adding 3-4 inches of mulch helps considerably. Dahlia tubers can be dug after frost, then place in paper bags or boxes of sand in a cool place and sprinkle a little water on the tubers periodically to keep them from drying out.
- Full Sun to Partial Shade

- Moderate Consistent Moisture
- Lift Tubers in Cold Growing Zones in Fall After Frost
