Corinna Schumacher – hybrid tea rose propagation material
Premium own-root pharmaROSA® NEONATAL material of Corinna Schumacher provides a stable base for nursery propagation beds and premium container production where flower quality and high-centred, cut-rose-type buds are commercially decisive. The upright, compact habit (70–90 cm) and 35–50 cm spread support dense, homogeneous stands in 5–7 L containers, with scope to step selected plants into 40–50 litre and larger feature pots for specimen use. Repeat, remontant flowering with an abundant second flush underpins season-long bench presence for exclusive finished product ranges. Very strong, long-lasting fragrance and premium-gold cultivar rating help differentiate retail and reseller offers in thematic rose gardens and collection schemes. Own-root production promotes long-term longevity, regenerative capacity and low replacement in stock beds, aligning well with UK nursery networks serving public-realm and institutional projects in conditions demanding reliable winter hardiness and wind tolerance in northern regions. Moderate disease resistance with black-spot resistance supports a medium-maintenance regime, manageable within standard protection programmes. As a Guillot-bred hybrid tea, this cultivar supports branding-oriented, exclusive lines and private-label rose collections. From semi-finished cutting to finished stock, development typically follows a practical arc of root establishment in year one, framework shoot building in year two and full ornamental display from year three onward.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Corinna Schumacher hybrid tea rose, Hybrid Tea group and commercial type, current trade name “Corinna Schumacher – white hybrid tea rose – Guillot”; American Rose Society exhibition name: Corinna Schumacher; registered cultivar name not provided. |
| Origin and breeding |
Bred by Georges Guillot, Roseraies Pierre Guillot, France; breeding year 2011 with parentage unknown; initially distributed by Roseraies Guillot in 2011 as a hybrid tea rose developed for premium ornamental and cut-flower style use. |
| Awards and recognition |
Not provided; no competition, collectors’ or global awards are listed for this cultivar, and no external horticultural rating data are available beyond the internal premium gold quality classification noted here. |
| Growth and structural characteristics |
Upright habit with 70–90 cm height and 35–50 cm spread; moderately dense, mid-green, slightly glossy foliage and moderate prickliness; self-cleaning ability not specified and likely to require manual deadheading due to double, turbinate flowers. |
| Flower morphology |
Hybrid tea, high-centred, pointed-budded form ideal for exhibition and cut-rose styling; solitary blooms with 26–39 petals, fully double, large-sized flowers (approximately 2.75–3.95 inches) and strong remontant habit with abundant second flowering. |
| Colour data and phenology |
White flowers with soft pale pink at petal bases (ARS PB; RHS 155D, 62D); ivory buds with pinkish tips open to bright white, then pale to creamy white as pink tones recede; moderate colour retention with subtle toning through full bloom and fade. |
| Fragrance and aroma |
Very strong, intense, long-lasting scent; exact fragrance character not described but clearly noted as powerful ornamental perfume; highly double blooms limit stamen access, so despite fragrance it is of low attractiveness to pollinators in production settings. |
| Hip characteristics |
Forms small, spherical orange-red hips, approximately 10–14 mm in diameter; hips are produced only in small quantities, so fruit display is modest and typically secondary to its primary ornamental and cut-flower style flowering role. |
| Resistance and winter hardiness |
Rated to approximately –21 to –18 °C (USDA zone 6b, Swedish zone 3, RHS H7); disease profile shows black-spot resistance with moderate susceptibility to powdery mildew and rust, corresponding to a medium maintenance requirement with occasional plant protection. |
| Horticultural recommendations |
Suited for flower beds, specimen planting and cut-flower style use; recommended as bush-trained with 3–5 framework canes for premium container production (5–7 L pots) under medium maintenance; heat and drought tolerance not provided and should be locally tested. |
