More information
Ilse Krohn Superior is a repeat-flowering climber that originated as a sport from a once-flowering rose. The sport was intended to be a dwarf crabapple, but the result is a vigorous, low climber suited to small gardens. Used as a large-flowered white climber in cold climates. Buds are elongated, creamy white; large petals begin to curl as the flower opens, similar to a large hybrid tea. Blooms are very double; petals are thick and waxy, with a slight creamy-yellow tint at the center. Flowers appear singly or in small clusters of up to 3 and may nod slightly. Flowers tolerate rain; foliage is dark and glossy. The variety shows disease resistance; canes are arching.
The flowers are bright white with a creamy tinge in the center; the petals are curved. Flowers reach 13–14 cm in diameter, are very double, with a high center, and open from elongated buds in clusters of 3–5. Withstands rain. The shrub is very hardy, strong-growing, up to 3 m. Suited to cold climates as a large-flowered white climber.

Flowers are creamy white with yellowing in the center, goblet- to cup-shaped, large (7–9 cm), very double (75–90 petals), fragrant, in inflorescences of 5–15 on long, sturdy pedicels. Leaves are dark green, large, leathery, shiny. Spines are large. Shrubs reach up to 2 m, spreading, with whip-like shoots. Blooms abundantly and for a prolonged period; weakly remontant. Sets hips.
