Tulipa Single Late 'Catherina'

Tulip

Catherina is a Single Late tulip, known for its large, creamy-white, egg-shaped flowers with broad ivory-white petal edges and a buttercup-yellow base. It blooms in late spring, standing on tall, sturdy stems that reach 24 inches.

This variety thrives in full sun to partial shade with well-drained soil and is prized for its classic, elegant form, making it a standout in borders, cut flower arrangements, and mass plantings. A popular alternative to the classic Tulip Maureen which is no longer widely grown.

Growing and Maintenance Tips for Tulipa Single Late 'Catherina'

Planting: Plant in fall when soil temperatures drop below 55°F. Set bulbs 6–8 inches deep with the pointed end up. Choose a sunny, sheltered site to protect their tall stems and graceful blooms from wind.
Spacing: Space bulbs 4–6 inches apart. For a dramatic effect, plant in groups of 10 or more—ideal for borders, cutting gardens, or formal displays.
Light: Full sun encourages strong stems and rich color. While light shade is tolerated, consistent sun enhances bloom longevity and form.
Soil: Use well-drained, neutral to slightly acidic soil (pH 6–7). Avoid poorly drained areas—French tulips are sensitive to bulb rot in wet spring conditions.
Watering: Water after planting to settle the soil. In spring, water only during prolonged dry spells to maintain bloom integrity without over-saturating the roots.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) for root development and bud initiation.
Fertilization: Apply a balanced bulb fertilizer when planting and again in early spring as shoots emerge to support stem strength and bloom quality.
Pests: Squirrels may disturb bulbs—use mesh or mulch to deter them. Deer will eat buds and foliage, especially early in spring, so use fencing or repellents in high-pressure areas.
Disease: To prevent Botrytis (Tulip Fire), plant only healthy, firm bulbs in sunny, well-ventilated areas. Avoid overhead watering and remove any infected material—never compost. Rotate planting zones annually and avoid replanting in affected sites for at least three years.
