We love the selection of bulbs available from A.D.R. The variety is great, the quality is excellent and the price is fair. However, the best part of working with A.D.R is the customer service from Chris, Walter and all of the team. They go out of their way to make sure ours needs are met.

Growing and Maintenance Tips for Tulipa Triumph 'Purple Flag'

Planting: Plant in fall when soil temperatures drop below 55°F. Set bulbs 6–8 inches deep with the pointed end up. Triumph tulips adapt well to borders, containers, and large-scale plantings thanks to their uniform habit and wide color range.
Spacing: Space bulbs 4–6 inches apart. For a cohesive display, plant in groups of 10 or more—ideal for both solid color blocks and curated mixes.
Light: Full sun encourages strong, upright stems and bold color. While light shade is tolerated, performance is best with at least 6 hours of direct light.
Soil: Provide well-drained, neutral to slightly acidic soil (pH 6–7). In poorly drained areas, amend soil or raise beds to prevent bulb rot.
Watering: Water after planting to settle the soil. During spring, water only in extended dry spells—too much moisture can shorten bloom duration.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) for proper rooting and flower initiation.
Fertilization: Apply a balanced bulb fertilizer when planting and again in spring as foliage emerges to support stem strength and bloom quality.
Pests: Squirrels may dig recently planted bulbs—use mulch or mesh to deter them. Deer will eat buds and foliage, especially in early spring, so apply repellents or fence vulnerable areas.
Disease: To prevent Botrytis (Tulip Fire), plant only healthy bulbs in sunny, airy spots. Avoid overhead watering. Remove and destroy any infected plant material—do not compost. Rotate planting locations yearly and avoid replanting in previously affected sites for three years.
