Bourbon roses are generally believed to be the result of an accidental cross between the china “Old Blush’ and the autumn flowering damask, ‘Quatre Saisons’. The name comes from the island where they arose, Ile de Bourbon, now called Reunion, located in the Indian Ocean off the coast of Madagascar. Farmers on the island planted the two kinds of roses in boundary hedges and the spontaneous hybrid that resulted was the first bourbon rose, perhaps ‘Rose Edouard’, Bourbon roses were first introduced into France in 1823 and became very popular in Europe between 1830 and 1850 because of their intense fragrance, and beautiful color and form.
The plants are generally vigorous, and have an open habit with arching stems and glossy leaves. Colors include pink, white, blush and deep red. Climbing forms are available. Unfortunately, they tend to be susceptible to mildew and blackspot making them more suitable to dry climates.
