Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Planting: In spring, plant tubers 3 to 4 inches deep with the eye facing up, once soil has warmed to at least 60°F. Space 24 to 36 inches apart to accommodate their tall stature and massive blooms.
Location: Full sun (6–8 hours daily) is essential. Choose a sheltered spot to protect from wind, as the large flowers can be top-heavy.
Soil: Rich, loamy, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Amend with compost or decomposed leaves for aeration and fertility.
Watering: Water deeply 1–2 times per week, increasing during hot, dry spells. Avoid watering until shoots emerge to prevent rot.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift tubers after frost and store in a cool, dry place.
Fertilization: Feed every 2–3 weeks with a balanced or low-nitrogen fertilizer. Overfeeding nitrogen can reduce bloom size.
Pruning: Pinch back when plants reach 12 inches tall to encourage branching. Disbud (remove side buds) to direct energy into fewer, larger blooms. Deadhead regularly to extend flowering.
Staking: Essential. Use tall stakes or cages early to support stems and prevent flopping under the weight of 10–12 inch blooms.
Pest & Disease: Watch for aphids, spider mites, and powdery mildew. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each has at least one viable eye.
