Petra's Perpetual – pharmaROSA® NEONATAL own-root propagation material
Vertical production opportunities characterise Petra’s Perpetual as a carmine-red climber delivering exclusive, space-defining features for trained climber programmes, with own-root sustainability supporting long-term nursery stock and reliable propagation cycles. Its dense, mid-green foliage and strong hardiness (H7, down to -32–-29 °C, USDA 4b, Swedish zone 5) make it suitable for exposed UK sites where winter and wind are factors, while resistant foliage simplifies crop protection planning. Highly remontant cluster-flowered singles with a fruity, moderately strong fragrance and good pollinator accessibility provide season-long ornamental value for retail and project ranges focused on distinctive vertical garden features. As pharmaROSA® NEONATAL tray-rooted own-root propagation material, 3–6‑month-old cuttings develop a durable framework under your conditions, supporting Year 1 root establishment, Year 2 structural shoot build-up and Year 3 full ornamental expression in finished product. Delivered for onward training into staked, 3–5-cane climbers in 5–7 L and larger containers, the cultivar’s resistance, low-maintenance profile and pollinator-supporting flowers back professional production for retail/reseller channels and thematic rose collections, while own-root longevity underpins predictable capacity planning.
