| Origin and breeding |
Bred by Teizō Yoshiike in Japan, 2009; parentage Heritage × Amber Queen; introduced after 2011, ARS registration 2011; detailed breeding company and initial distributor data not provided. |
| Awards and recognition |
Gold Medal at Nagaoka International Fragrant Rose Trials, Echigo Hillside Park (2009), and Best Rose Award at the 3rd Japanese National Fragrant Rose Competition, Echigo Hillside Park, 2009. |
| Growth and structural characteristics |
Upright shrub, approx. 110–170 cm high and 60–100 cm spread, moderately dense glossy dark green foliage, moderately thorny, poor self-cleaning so regular deadheading of spent blooms is advisable in production. |
| Flower morphology |
Large L-sized blooms (2.75–3.95 in), very full with 40+ petals, rosette form in clustered inflorescences; remontant flowering with abundant second flush, suitable for ongoing display in premium shrub and container production. |
| Colour data and phenology |
Delicate warm apricot-peach, lighter at petal edges; buds deep peach to salmon, opening to rich peach and cream, then pastel peach and finally pale cream-peach; moderate colour retention, holding better in cooler conditions. |
| Fragrance and aroma |
Strong, distinctive fragrance combining fruity and tea-scented notes; very double flowers usually conceal stamens, so pollinator value is limited and it is chosen primarily for ornamental and scent qualities. |
| Hip characteristics |
Produces rose hips in moderate quantities; globe-shaped, approximately 10–15 mm diameter, orange-red colour, adding some late-season interest but generally secondary to its primary flower display role. |
| Resistance and winter hardiness |
Medium overall disease resistance: very susceptible to powdery mildew, resistant to black spot, medium against rust; hardy to about −21 to −18 °C (RHS H7, Swedish zone 3, USDA 6b); tolerates heat with watering in prolonged drought. |
| Horticultural recommendations |
Recommended for flower beds, specimen and container use, and as a cut-flower companion; moderate maintenance with occasional plant protection for powdery mildew; supplied bush-trained with 3–5 canes for premium container production paths. |
Masora combines strong flower impact, distinctive fragrance and reliable heat tolerance in an own-root form that supports predictable, regenerating stands over time; it may be worth aligning capacity and scheduling for your premium Romantic rose programmes.
