Dinnerplate Dahlia Spectacular – 5 Premium Dinnerplate Dahlia Tubers
Make a bold statement in your garden with these 5 show-stopping dinnerplate dahlia tubers. This collection includes Kelvin Floodlight (golden yellow), Mrs. Eileen (soft pink and white), Noordwijks Glorie (warm orange-pink), and Thomas Edison (deep purple) — plus one bonus variety. Each produces massive blooms up to 10 inches across that are absolutely breathtaking in the garden or in a vase.
Planting Instructions: Plant tubers in spring after all danger of frost has passed and soil is warm (60°F+). Plant 4–6 inches deep with the eye pointing up. Space 18–24 inches apart to allow for their large growth habit. Install stakes at planting time to avoid damaging tubers later. Water sparingly until growth appears, then increase watering as plants develop.
Growing Conditions: Full sun is essential for the biggest blooms (6–8 hours minimum). Plant in rich, well-drained soil amended with compost. Hardy in USDA Zones 8–10; in colder zones, dig and store tubers after the first frost. Pinch the center growing tip above the third set of leaves to encourage bushier growth with more blooms. Feed with a low-nitrogen fertilizer every 2–3 weeks.
What to Expect: These dinnerplate dahlias reach 4–5 feet tall and begin blooming in mid to late summer, continuing until frost. The enormous blooms in shades of yellow, pink, orange, and deep purple create an unforgettable garden display. Each plant can produce dozens of flowers over the season. These are premier cut flowers — a single bloom can fill a small vase on its own!
