Keitsupiatsu Romantica® KEItsupiatsu – pharmaROSA® NEONATAL own‑root climber
This climbing Romantica® cultivar offers a vertically focused, exclusive solution for nursery and wholesale partners seeking a reliable, own‑root base for trained pergola and wall features. As a sport of ‘Yves Piaget’, it combines proven garden performance with a strongly scented, very double XL bloom form in a warm fuchsia‑pink palette, well suited to collection plantings and show‑garden projects where a distinctive structural specimen effect is required. On own roots, it supports long‑term, renewable growth and stable stands, aligning with UK nursery systems that must cope with varied conditions from cooler northern areas to milder, more exposed sites with good winter and wind tolerance. With a recommended grow‑on route as a staked, trained climber finished product in 5–7 L containers, it can be integrated into production flows targeting vertical garden feature lines and reseller‑oriented ranges, building predictable capacity as roots establish in year one, framework develops in year two, and full ornamental value is reached by year three for sustainable collections.

| Fragrance and aroma |
Very strongly scented cultivar with a sweet-citrus, classic rose fragrance character, clearly detectable from a distance and suitable for fragrance-led garden concepts and climber assortments. |
