Emilien Guillot™ Générosa® MASemgui – pharmaROSA® NEONATAL rooted cutting
Premium own-root pharmaROSA® NEONATAL material of Emilien Guillot™ offers romantic flower quality for growers building an exclusive container line, with bush-trained, 3–5 cane framework ideal for a cut-flower capable shrub in premium 5–7 L production. The very double, XL rosette blooms deliver colour-focused impact and strong fragrance as a distinctive specimen or edge element in thematic and collection gardens, while own-root longevity supports stable, low-replacement beds in UK nursery and municipal supply contexts, including harsher northern sites with reliable winter and wind tolerance. Medium maintenance needs and good heat and drought tolerance suit professional grow-on where predictable quality and nostalgic flower form underpin a long-term, own-root rose portfolio, following a natural development arc of root establishment in year one, structural canopy in year two, and full ornamental performance from year three onward.

Technical cultivar profile
| Name and registration |
Emilien Guillot™ Générosa®, registered as MASemgui; Romantic nostalgia shrub rose, ARS exhibition name Emilien Guillot, verified authenticity under pharmaROSA® NEONATAL own-root production. |
| Origin and breeding |
Bred by Dominique Massad for Roseraies Guillot, France; bred 1997, introduced and registered 2001, continuing the Générosa® Romantica shrub tradition with emphasis on bloom quality and fragrance. |
| Growth and structural characteristics |
Bushy shrub 75–105 cm high and 55–75 cm wide, dense glossy dark green foliage, moderately thorny canes; supplied bush-trained with 3–5 strong framework canes for rapid, balanced canopy formation. |
| Flower morphology |
Very double, 40+ petalled XL rosette blooms, cluster-flowered on bushy stems; remontant with a less abundant second flush, requiring some manual deadheading due to weak self-cleaning performance. |
| Colour data and phenology |
Vibrant deep orange-red flowers, vermilion-orange in bud, fading through coral and pastel pink tones; moderate colour retention, with softer coral-pink shades developing under strong light and over time. |
| Fragrance and aroma |
Strong, distance-carrying scent with a rich fruity-spicy character; designed primarily as an ornamental and cut-flower type, with very double blooms limiting pollinator access rather than wildlife utility. |
| Hip characteristics |
Hip set generally limited by very double flowers; where present, spherical hips 8–12 mm across, orange-red in colour, contributing modestly to late-season interest without major seeding impact. |
| Resistance and winter hardiness |
Hardy to approximately -21–-18 °C (USDA 6b, H7, Swedish zone 3); black spot resistant with medium susceptibility to powdery mildew and rust, and good heat tolerance given regular irrigation in drought. |
| Horticultural recommendations |
Suited to flower beds, edging, specimens, parks and cut use; recommended as premium container product in 5–7 L pots, medium maintenance with occasional pest control and manual removal of spent blooms. |
