Zwergenfee 09® – pharmaROSA® NEONATAL own-root propagation material
Zwergenfee 09® offers a compact, bushy habit and dense, glossy foliage that translates directly into uniform, saleable mini-rose containers from 1.5–2 L upwards, with scope to step selected batches on into 40–50 litre specimens for high-impact patio and show displays. Its semi-double raspberry-red flowers in tight clusters give an instant colour effect in small spaces, supporting impulse-driven retail concepts and patio-focused ranges where continuous presence on the bench matters. The variety’s ADR-certified resistance and H7 winter hardiness underpin reliable performance in UK nursery networks, including cooler Scottish and northern English conditions with demanding winter and wind exposure. As own-root pharmaROSA® NEONATAL material, it provides stable, regenerating stands with low replacement needs and predictable capacity over multiple cropping cycles, well suited to integrator systems and public-realm suppliers building thematic rose collections. Moderate self-cleaning reduces detailed grooming, aligning with low-maintenance production objectives and fast bench turnaround. Repeat-flowering habit maintains ornamental value between dispatch windows, while year 1 root establishment, year 2 structural shoot build-up and year 3 full ornamental expression allow precise scheduling of finished-product peaks. With multiple international awards supporting professional credibility, Zwergenfee 09® forms a dependable component in a broad own-root assortment aimed at patio and container mini-rose programmes.
