More information

For 50 years General Jacqueminot was the most widely grown red rose worldwide. It was used both as a garden plant, due to abundant bloom, and as a cut rose. It was widely employed in breeding and is cited as a progenitor of almost all red roses. Buds are bright crimson-red; as they open, blooms become globular and the color shifts toward purple. The undersides of the petals are paler, and some petals show white streaks. The flowers are not very double and tend to droop under their own weight. Blooms are borne singly or in clusters of 2–3. The bush is very spiny, with bright green foliage. Black spot or powdery mildew may occur, but with good culture the plant shows greater disease resistance. Deadheading increases the abundance of repeat bloom.

A bright red remontant hybrid, General Jacqueminot was introduced in 1853 and remains in cultivation. Elongated buds open into fragrant double flowers with wavy petals. The flowering period is longer than in most remontant hybrids. The bush reaches 1.2 m in height and has a somewhat untidy habit. The foliage is tough and susceptible to powdery mildew and rust. Shoots are prickly. Heavy pruning is required each spring.

This rose contributed to the development of many modern red roses. Flowers are carried on long shoots, strongly scented, densely crimson with scarlet hues. The bush is vigorous, with bright green foliage, reaching 1.5 m; rust can occur in the second half of the season.

Long flowering shoots made this variety the first cut rose. Flowers are 6–10 cm in diameter, cup-shaped, bright red, and strongly fragrant, with 25–30 petals and a whitish bloom on the petal undersides. Often regarded as a prototype of the remontant hybrid class. The bush is branched, 120–150 cm, with bright green foliage. The rose is often referred to as General Jack.
