Spinnaker Amorina – pharmaROSA® NEONATAL rooted cutting
Uniformity in Spinnaker Amorina makes it a dependable base cultivar for project-driven bed and park production, where coverage speed, clean presentation and predictable stand behaviour are critical for public and institutional planting schemes. Its compact, dense growth, glossy dark foliage and good self-cleaning performance support low-maintenance concepts in high-traffic landscape beds, and its white, semi-double clusters offer consistent ornamental impact across long flowering sequences. With robust hardiness to H7 / USDA 4b and proven disease resistance, it suits UK nursery networks serving large-scale, weather-exposed municipal projects, benefiting areas where winter and wind tolerance are essential in repeated contract planting cycles. As own-root pharmaROSA® NEONATAL material (tray-grown, 3–6 months) it provides a renewable structure – roots consolidating in year one, shoots building mass in year two, and full ornamental value stabilising from year three – aligning well with scheduled project mass-planting and short-rotation 1.5–2 L container routes under a professional, collection-oriented portfolio.
