- Group
- Repeat-flowering (Hybrid Perpetual)
- Breeder
- Charles Verdier, France, 1884
- Bud shape
- A dense dark bud of old-fashioned type
- Open flower
- Cupped, wavy, quartered — the classic form of an old garden rose; ~8 cm; singly or in small clusters
- Centre
- Filled with numerous petals, often quartered, with a swirl at the centre
- Colour
- Deep dark red, garnet-raspberry velvet with dark shadows; almost black-purple in cool weather. The colour changes: as the flower fades and in the heat it takes on purple-violet, mauve-crimson tones, so the bush shows velvety dark fresh flowers and flowers already 'faded to violet' at the same time
- Fullness
- Very double — 41+ petals
- Flower carriage
- Solitary flowers or small clusters
- Flowering
- Repeat-flowering: main flush June–July, plus a weaker autumn repeat
- Fragrance
- Strong, intoxicating — a generous, dense scent of an old garden rose: warm, sweet and honeyed, with velvety depth
- Hips
- No data
- Habit
- A spreading bush with long, flexible shoots; can be trained as a low climber
- Branching
- Long flexible shoots, suitable for tying to a support
- Shoots
- Long, flexible, almost thornless — this is why the RHS also registers a climbing form, ClHP (this is more a feature of the habit than a separate variety)
- Thorns
- Shoots almost thornless — easy to train along a support.
- Dimensions
- Data varies: bush 80–160 cm OR 1.8–2.5 × 1.2–1.8 m as a small climber
- Support
- Recommended — the long flexible shoots can be trained as a low climber on a support
- Foliage
- No data
- Resistance
- No data; as an old HP it may be affected by powdery mildew and black spot in damp weather
- Variations of the variety
- Not to be confused with 'Souvenir du Docteur Jamain' — both are very dark repeat-flowering roses, and on the market they are often sold under each other's name. The variety has no code name
