Frothy – Mini – dwarf rose – MACfrothy
Compact own-root pharmaROSA® NEONATAL material of Frothy offers a reliable bushy base for nursery container lines and edging stock where uniform miniature structure and dense, moderately glossy foliage are important for repeatable, small-space displays. Its very full, rosette flowers remain within a tight, S-sized profile, supporting impulse-focused 1.5–2 L patio products aimed at garden-centre and nursery channels. Medium maintenance needs and documented H7 hardiness support planning for UK-wide distribution, including cooler zones with strong winter and wind tolerance in exposed nursery sites. The remontant, abundant second flush sustains the display value of finished stock through a long sales window, while low hip set and non-pollinator-oriented, pure white blooms help maintain a clean, ornamental look in thematic rose gardens and collection-style, own-root stands intended for long-term renewal. The own-root form builds progressively—roots in year one, structure in year two, and full ornamental value from year three, supporting predictable, low-replacement programmes.
