I’ve been purchasing bulbs from A.D.R. for many years. The quality is superior and the service fantastic. Chris and his family have always been prompt and accommodating. If you need it, Chris can find it! I wouldn’t shop anywhere else!

Dahlia 'Isabel' is a ball-type dahlia featuring bright lavender flowers with coral accents toward the center. The blooms, about 3 inches wide, create a charming display, especially when paired with late-season asters and tall grasses. This variety grows up to 44 inches tall and thrives in full sun with consistent moisture and well-drained soil. Blooming from midsummer until frost, 'Isabel' is an excellent choice for garden borders, floral arrangements, and pollinator-friendly plantings. Hardy in zones 3-7, it requires lifting and storing in colder climates before winter.

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 18 to 24 inches apart to allow for airflow and mature spread.
Location: Full sun (6–8 hours daily) is essential for strong stems and abundant blooms.
Soil: Fertile, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost before planting.
Watering: Water deeply once or twice a week, keeping soil evenly moist but not soggy. 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: Apply a balanced fertilizer monthly or use a slow-release formula at planting and midsummer. Avoid high-nitrogen feeds.
Pruning: Pinch back when plants reach 12 inches tall to encourage bushier growth. Deadhead regularly to promote continuous bloom.
Pest & Disease: Watch for aphids, spider mites, and fungal issues. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each division has at least one viable eye.
