Michka ® Climbing rose MEIvaleir – pharmaROSA® NEONATAL rooted cutting
Climbing production of Michka ® MEIvaleir as pharmaROSA® NEONATAL material offers a stable base for vertical rose ranges, with tray-rooted, 3–6‑month own-root cuttings that are easy to integrate into nursery workflows and scalable to high‑volume trained climber programmes. Its upright habit with small shoots, dense foliage and 4.8–7.5 ft height supports space‑defining finished plants for pergolas, arches and walls in thematic rose gardens and collection projects. The remontant, very full flowers in warm golden‑yellow with orange‑red colouring create an exclusive, vertical garden feature for retail and reseller channels, while good heat and drought tolerance fits UK networks supplying sunnier southern and more exposed sites, with reliable performance even in wind‑affected northern plantings as part of a nationwide supply strategy. Own‑root longevity underpins predictable, low‑replacement stock for hedge and specimen uses, and supports a practical development arc where roots establish in year one, structural canes build in year two and full ornamental value is achieved from year three onwards in 5–7 L trained climber production.
