A highly fragrant and floriferous species with an upright growth and deciduous leaves. This is one of the parents of D. x burkwoodii and D. x transatlantica, both include exceedingly desirable and equally popular varieties. Their fragrance? You guessed it, is inherited from D. caucasica. Very easy in full sun (not in very hot climates,) to half shade in a well drained soil. Since the plants can get quite tall, pinching and pruning in the first years is recommended for achieving a bushy growth. Later on, the size can be kept down easily by trimming.
