Numerous cultivars have been developed for ornamental use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:[6]
- 'Big Ben'[7]
- 'Limelight' (PBR)[8]
- 'Phantom'[9]
- Template:Tdes = 'Interhydia'[10]
- Template:Tdes = 'Dvppinky' (PBR)[11]
- 'Silver Dollar'[12]
Those cultivars marked (PBR) are protected by plant breeders' rights from unauthorised propagation.
Other cultivars include:
- 'Praecox',[13] a particularly early flowering cultivar
