Maria Callas® – Hybrid tea rose – MEIdaud
Premium own-root pharmaROSA® NEONATAL material of Maria Callas® gives You a stable basis for high-end hybrid tea production, with tray-grown cuttings suited to bush-trained, 3–5‑cane formation and a vigorous, upright framework that finishes reliably into 5–7 L containers. The large, high‑centred blooms and very full, solitary flower form support cut flower and exhibition-grade outputs where consistent, deep pink colour and strong, long-lasting scent justify an exclusive positioning in retail and reseller channels. Own-root structure underpins long-term collections and cultivar maintenance for show gardens in the UK, providing homogeneous stands and reduced replacement over time, while offering dependable performance in cooler northern regions with winter and wind-tolerant robustness. When scheduled as 3–6‑month tray-rooted material, the development arc of Year 1 root establishment, Year 2 framework build, and Year 3 full ornamental expression can be integrated predictably into nursery planning for premium hybrid tea ranges.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose, registered as MEIdaud, traded as Maria Callas® hybrid tea rose; also known in exhibition use as Miss All-American Beauty within the hybrid tea exhibition category. |
| Origin and breeding |
Bred by Marie-Louise Meilland at Meilland International, France, from ‘Chrysler Imperial’ × ‘Karl Herbst’; introduced and registered in 1965 with Meilland International as initial distributor. |
| Awards and recognition |
Recognised with the Portland Gold Medal in 1966 and selected as an All-America Rose Selections winner in 1968, confirming long-term acceptance in high-quality hybrid tea evaluation. |
| Growth and structural characteristics |
Upright hybrid tea shrub reaching around 130–170 cm in height with a 70–95 cm spread, dense dark green glossy foliage, and densely thorned shoots; weak self-cleaning means spent blooms generally need removal. |
| Flower morphology |
Very full, solitary, high-centred, pointed-budded hybrid tea flowers with 40+ petals and large 2.75–3.95 inch diameter, remontant with abundant second flowering providing good ornamental and cut suitability. |
| Colour data and phenology |
Rich deep pink blooms (ARS dp; RHS 57B outer, 57C inner), generally retaining colour well, with slight lightening towards edges and in strong sun; petals can scorch and fade slightly under intense sunlight exposure. |
| Fragrance and aroma |
Classed as a strongly scented hybrid tea with long-lasting fragrance; detailed scent profile data are not available, but the variety is primarily valued for combining strong colour and significant scent intensity. |
| Hip characteristics |
Hip production is limited by the very double flowers; when present, hips are egg-shaped, orange-red, around 10–14 mm in diameter, and generally of minor relevance for most ornamental or production objectives. |
| Resistance and winter hardiness |
Moderate resistance to powdery mildew, black spot and rust; hardiness around -15 to -12 °C (RHS H6, Swedish zone 2, USDA 7b), with moderate heat and drought tolerance requiring regular watering in warm periods. |
| Horticultural recommendations |
Suited to borders, cut flowers and specimen use, with medium maintenance needs and occasional pest or disease control; best produced as bush-trained plants on 3–5 canes, via premium container routes in 5–7 L pots. |
