- Flowering
- Mostly one abundant flush in spring or early summer; repeat flowering is weak and irregular. Do not treat it as repeat-flowering.
- Fragrance
- ONE OF THE MOST FRAGRANT ROSES altogether — very strong, warm, honeyed-spicy with a fruity-tea note; the scent spreads especially in the evening. This is the variety's main virtue.
- Habit
- A strong, large climber (Climbing HT / Large-Flowered Climber) — long, vigorous canes
- Branching

- Support
- A sturdy support is essential — a wall, arch, pergola or trellis; a well-ventilated spot is preferable
- Foliage
- In damp, shaded spots it is prone to black spot and powdery mildew — good air circulation is needed
- Variations of the variety
- No code name — an old variety (~1937–1938)
