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: Plant rhizomes in spring or fall, 1 to 2 inches deep with the crown just below soil level. Space 12 to 24 inches apart. Water well after planting to settle the soil.
Location: Full sun to partial shade. In hot climates, light afternoon shade helps prevent leaf scorch.
Soil: Moist, well-drained, slightly acidic to neutral soil (pH 5.5–7.0). Enrich with compost or peat moss if needed.
Watering: Keep soil consistently moist during the growing season, especially in spring and early summer. Tolerates brief dry spells once established.
Temperature: Hardy in USDA zones 3–8. Cold-tolerant and thrives in northern climates.
Fertilization: Apply a balanced fertilizer in early spring and again after flowering. Avoid high-nitrogen formulas.
Pruning: Remove spent flower stalks and yellowing foliage. Cut back to the ground in late fall or early spring.
Propagation: Divide clumps every 3 to 4 years in late summer to maintain vigor and prevent overcrowding.
Pest & Disease: Low-maintenance and generally pest-free. Good air circulation helps prevent fungal issues.
