I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Dahlia Cactus 'Purple Gem' (Ships in Spring)

Dahlia

Dahlia 'Purple Gem' is a semi-cactus variety known for its deep violet-purple blooms with long, pointed petals that create a dynamic, spiky effect. The flowers, typically around five inches in diameter, shimmer in the light, adding a dramatic presence to garden beds and floral arrangements. This dahlia reaches a height of approximately 36 inches with a spread of 18 to 24 inches, forming a bushy, upright habit. Blooming from mid-summer until frost, it thrives in full sun and well-drained soil, making it a reliable choice for borders, containers, and cutting gardens. It attracts pollinators such as bees and butterflies while offering some resistance to deer and rabbits. Hardy in USDA zones 8 to 11.

Growing and Maintenance Tips for Dahlia Cactus 'Purple Gem' (Ships in Spring)

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 accommodate their vigorous growth and airflow needs.
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.
