POSTILLION ® – yellow park rose – Kordes (KORtionza)
Postillion offers a reliable own-root base for nurseries seeking stable shrub-rose volume in standard containers, combining a remontant flowering habit with robust H7 winter hardiness to support predictable scheduling. Its upright, 120–180 cm shrub structure and moderately dense, glossy foliage provide a consistent framework for 2–3 L production aimed at retail and reseller channels, where dependable garden performance and clear park-rose positioning are key. The warm saffron-yellow colour range, with semi-double clusters suited to shrub and cut-flower use, aligns well with thematic rose gardens and collection plantings. Own-root propagation underpins long-term stand stability and regeneration, allowing capacity planning for public-realm and institutional projects in climates where it confidently handles Scottish and northern English winters with reliable frost and wind tolerance. From rooted cutting to finished stock, you can phase development naturally across three seasons—roots establishing in year one, structural shoots forming in year two, and full ornamental expression from year three onward.
