Green Ice – pharmaROSA® NEONATAL rooted cutting for professional production
Miniature growers seeking compact, impulse-ready patio lines can build repeatable programmes on Green Ice NEONATAL material: a dense, low, spreading shrub with reliable remontant flowering and very good self-cleaning, ideal for efficient container-turn cycles and edging or basket concepts where labour must stay controlled. The own-root propagation base supports homogeneous, medium-maintenance crops with predictable -26–-23 °C hardiness, suiting integrated nursery networks that must serve cooler UK regions where winter and wind exposure are common, while still offering an attractive retail-ready look in 1.5–2 L pots. With compact, cluster-flowered, double blooms in a distinctive white-to-pale-green colour play, Green Ice aligns naturally to “instant” small-space displays and patio concepts. Year 1 concentrates on rooting, Year 2 on structural framework, by Year 3 the finished plants show full ornamental value with stable performance, allowing You to plan staggered batches and consistent bench presentation. The cultivar’s hardiness, Mini–dwarf stature and glossy dark foliage all reinforce its role as a premium yet controllable container line within broad, own-root wholesale offers targeting thematic rose collections and coordinated garden-centre ranges.

Technical cultivar profile
| Aspect |
Data |
| Name and registration |
Mini – dwarf rose cultivar Green Ice, a miniature bush rose used for exhibition, baskets and groundcover; current trade name Green Ice Mini - dwarf rose Moore, ARS exhibition name Green Ice, own-root NEONATAL cutting form. |
| Origin and breeding |
Bred by Ralph S. Moore at Sequoia Nursery, Visalia, California, from (Rosa wichuraiana × ‘Floradora’) × ‘Jet Trail’; introduced and registered in 1971 in the United States, with Sequoia Nursery as initial distributor. |
| Awards and recognition |
Holds a Certificate of Merit from New Zealand (1973) and inclusion in the American Rose Society Miniature Rose Hall of Fame (2001), underlining long-term exhibitor and collector confidence in this miniature cultivar. |
| Growth and structural characteristics |
Compact, spreading low shrub reaching 40–50 cm in height with a 70–90 cm spread, dense glossy dark green foliage, slightly thorny shoots and a naturally tidy outline, aided by good self-cleaning of most spent blooms. |
| Flower morphology |
Small S-sized, 0.5–1.5 inch double, cup-shaped blooms with 26–39 petals, produced in clusters; remontant flowering with an abundant second flush, supporting sustained decorative effect in container, edging and basket uses. |
| Colour data and phenology |
Pure white base colour shifting to a delicate pastel green tint with age; in heat it remains mainly whitish, in cooler conditions a stronger green tone appears, with limited fading and a characteristic pale green phase before ageing. |
| Fragrance and aroma |
Very weak, barely noticeable scent with a delicately sweet character; double blooms can expose stamens when fully open, giving partial pollinator value and moderate attraction where stamen access is sufficient. |
| Hip characteristics |
Occasional, small spherical hips of about 5–7 mm diameter form, coloured orange-red; generally insignificant for display but indicating successful pollination in some settings and not usually impacting ornamental performance. |
| Resistance and winter hardiness |
Medium resistance to powdery mildew, black spot and rust; tolerates heat reasonably but needs irrigation in prolonged drought; winter hardy to about -26 to -23 °C, corresponding to RHS H7, Swedish Zone 4 and USDA Zone 5b. |
| Horticultural recommendations |
Best used for containers, edging, borders, groundcover and hanging baskets; maintenance level medium, with occasional pest and disease control; recommended as a compact, dense bush for 1.5–2 L patio products from own-root NEONATAL starts. |
Green Ice combines compact spreading habit, remontant cluster flowering and reliable H7 hardiness on a predictable own-root NEONATAL base, offering long-lived, homogeneous stocks for patio and edging lines where we welcome a discussion on scheduling and volumes.
