FRAU KARL DRUSCHKI – white historic perpetual hybrid rose – Lambert
Heritage own-root propagation material of Frau Karl Druschki gives professional growers a historically important, snow-white hybrid perpetual rose aligned to premium container and specialty routes, with a medium maintenance profile suitable for structured bed and park schemes where identity and long-term cultivar stability matter. As a non-remontant, once-flowering exhibition type with XL, double, cup-shaped blooms and medium disease resistance, it is best used in curated thematic collections and cut-flower heritage displays, particularly in cooler-summer regions where winter and wind tolerance supports reliable performance in open nursery beds and public settings. Dense, upright growth and strong prickliness call for considered spacing and discreet support in 5–7 L premium containers, evolving from root establishment in year one, to strong structural shoot development in year two, and full ornamental expression by year three, helping You plan predictable capacity and visually coherent stands. Onward propagation from tray-rooted, 3–6‑month-old, own‑root cuttings offers renewable stock with low replacement over time, fitting the needs of networked nurseries, public‑realm suppliers, and integrator systems that require reliable identity, consistent quality, and a classic white focal point for historic rose collections and cut-flower exhibition ranges.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Frau Karl Druschki, historical hybrid perpetual rose; current trade and ARS exhibition name as given, unregistered cultivar, part of a heritage rose collection line for professional production. |
| Origin and breeding |
Bred by Peter Lambert in Trier, Germany from ‘Merveille de Lyon’ × ‘Madame Caroline Testout’, introduced in 1901, representing an early twentieth-century white hybrid perpetual with documented breeder provenance. |
| Awards and recognition |
Awarded a National Rose Society (United Kingdom) gold medal as best hybrid perpetual rose circa 1907, supporting its use in historically referenced and exhibition-oriented heritage production ranges. |
| Growth and structural characteristics |
Upright habit to about 140–190 cm high and 100–160 cm spread, densely thorned with dense, slightly glossy foliage from light to dark green, suited to bush training with discreet support in structured beds. |
| Flower morphology |
XL, double, cup-shaped flowers with 26–39 petals, borne mainly solitary, non-remontant with a single main flowering flush, spent blooms persisting on the plant and generally requiring manual deadheading. |
| Colour data and phenology |
Pure, snow-white blooms (ARS W; RHS 155C outer, 155D inner) with bright, neutral tone, good colour retention and minimal fading; buds may remain closed in prolonged rain but do not develop creamy discolouration. |
| Fragrance and aroma |
Mild, softly sweet fragrance with a restrained scent profile; double, slightly closed flowers limit stamen access, reducing pollinator attraction and focusing value on visual ornamental and exhibition use. |
| Hip characteristics |
If not deadheaded, it may occasionally form small, 10–15 mm spherical, dark red hips, of incidental ornamental relevance and generally secondary to the main flowering display. |
| Resistance and winter hardiness |
Medium overall disease resistance with good tolerance to powdery mildew and black spot, medium rust sensitivity; very hardy (approx. −32 to −29 °C, RHS H7, Swedish zone 5, USDA 4b), prefers cooler summers. |
| Horticultural recommendations |
Best for flower beds, parks, cut-flower and specimen roles with medium maintenance; prefers cooler conditions, benefits from deadheading and occasional pest and disease control; recommended in 5–7 L premium containers. |
Frau Karl Druschki offers historic pedigree, pure white exhibition-quality blooms and high winter hardiness on predictable own-root stock, making it a reliable heritage choice for planned capacity and we would welcome aligning schedules and volumes with you.
