Gerbrand Kieft

Technical profile: the double architecture of Gerbrand Kieft

The Gerbrand Kieft variety belongs to the Late Double tulip class, which dictates its physiological specifics. Unlike standard goblet shapes, this cultivar features a multi-layered perianth structure. The tight layering of petals provides significant resistance to mechanical damage from wind gusts, which is critical for medium-height plants.

Phytosanitary resistance and habitus

The genetic foundation of Gerbrand Kieft ensures pronounced resistance to a complex of pathogens. Field testing confirms stability against Septoria and Fusarium, the most destructive fungal diseases of bulbous crops that typically attack the basal plate during vegetation. Furthermore, the variety demonstrates consistent immunity to powdery mildew, allowing for reduced fungicide applications in moderately humid environments.

• Flower morphology: Lush, multi-layered double form, often resembling peony-type tulips.
• Color spectrum: Intense red hue with distinct white striations or margins, governed by specific anthocyanin pigmentation.
• Stem height: The medium growth range provides an optimal balance between stem strength and flower head size, preventing lodging.

The practical application of this variety is focused on landscaping areas with prolonged flowering cycles. Its late growth habit allows the tulip to avoid late-spring frosts, while its complex petal structure requires moderately fertile soils with efficient drainage to fully realize the bulb's genetic potential.
