Spring Green

Engineering of the Viridiflora Class

The 'Spring Green' tulip is a benchmark of the Viridiflora class, defined by a distinct biological mechanism: the retention of chlorophyll structures within the tepals throughout the entire blooming cycle. Unlike standard cultivars where pigmentation relies solely on anthocyanins or carotenoids, this hybrid maintains vibrant green stripes along the midrib until senescence. This physiological trait significantly increases the density of the perianth tissues, contributing to greater overall durability.

Adaptability and Disease Resistance

For commercial cultivation, the hybrid's resilience to common pathogens is a defining advantage. 'Spring Green' exhibits robust resistance to key physiological and fungal threats:

• Fusarium Wilt: Selective breeding has significantly reduced the susceptibility of the root system to Fusarium fungi, ensuring stable yields during forcing or field production in high-moisture conditions.
• Downy Mildew (Peronospora): The specialized structure of the epidermal cells in the leaves and petals is less conducive to mycelial penetration, streamlining fungicide application protocols during volatile spring weather.

Agronomic Cycle

Classified as a late-blooming variety, this hybrid perfectly bridges the gap between early-season tulips and the onset of summer. Its medium-height stem provides an ideal balance of structural integrity, offering excellent resistance to lodging during wind events, which is often a critical failure point for taller varieties. The dense, sturdy bud structure ensures extended post-harvest shelf life and marketability, making 'Spring Green' a reliable performer for both landscaping and floristry, valued for its crisp, elegant white-and-green aesthetic.
