JAMES LEVIS

Maintenance and Cultivation of 'James Lewis'

Managing the 'James Lewis' herbaceous peony, developed by the Federal Research Center for Horticulture, requires professional attention to detail. Designed primarily for cut flower production, this cultivar reaches a height of 90 cm and produces massive 18 cm double blooms. To maintain the health of the plant, ensure planting in sunny, well-drained locations. Heavy clay soils require pre-planting amendments with organic matter and drainage materials to prevent root rot, which is a critical maintenance factor for this variety.

Key Technical Specifications

• Growth Habit: Herbaceous, necessitates structural support due to height and bloom mass.
• Flowering Window: Mid-season (May 31 – June 15), ideal for mid-spring inventory planning.
• Soil Requirements: High fertility and excellent drainage are non-negotiable for achieving maximum flower diameter.

The double-flowered structure of 'James Lewis' is highly sensitive to moisture accumulation during the budding phase. In a garden setting, proactive staking is essential, as the heavy blooms tend to weigh down stems during rain events. By performing regular maintenance—specifically balanced fertilizing and sanitary pruning—you ensure high yields of pristine white flowers, making this variety a reliable asset for both commercial cut flower operations and high-end garden design.
