Tulipa Double Late 'Black Hero'

Tulip

Tulip Black Hero is an extraordinary Double Late variety, celebrated as the double-flowered sport of the iconic Queen of Night. Its luxuriant, peony-like blooms are packed with layers of rich, velvety petals in deep mahogany-black tones, creating one of the darkest and most dramatic displays in the spring garden. Sturdy stems reach 18 to 24 inches tall, supporting substantial flowers that open to reveal a captivating depth of burgundy, plum, and near-black shades in changing light.

Growing and Maintenance Tips for Tulipa Double Late 'Black Hero'

Planting: Plant in fall after soil temperatures fall below 55°F. Set bulbs 6–8 inches deep, pointed end up. Choose a location with some shelter to help support the heavier, fully double blooms that emerge late in the season.
Spacing: Space bulbs 4–6 inches apart. For a bold effect, plant in groups of 10 or more—this amplifies the fullness of their densely petaled flowers.
Light: Full sun ensures the best floral display. They will handle light shade, but expect fewer blooms with less than 6 hours of sun.
Soil: Prefers well-drained, neutral to slightly acidic soils (pH 6–7). Avoid heavy or poorly drained spots to prevent bulb rot—especially important given their longer growth cycle.
Watering: Water after planting to settle the soil. In spring, water during prolonged dry spells, ensuring the soil doesn’t stay soggy as these large blooms are more prone to damage from excess moisture.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) to develop strong roots and initiate flower buds.
Fertilization: Apply a balanced bulb fertilizer at planting and again in spring as shoots appear to support robust stems and large flowers.
Pests: Typically low-maintenance. Mulch or mesh can help deter squirrels. Provide good drainage to avoid rot. Deer will eat the flower buds or emerging foliage, especially in early spring. Protect with fencing or repellents in high-pressure areas.
Disease: To help prevent Botrytis (Tulip Fire), plant only healthy bulbs in sunny, airy locations with good drainage. Avoid overhead watering, and remove any suspect foliage immediately—do not compost. Rotate plantings regularly; if Botrytis has occurred, avoid the site for at least three years.
