I planted them in a spot expecting growth similar to H. syriacus, which is a slow grower in my heavy clay soil. By their third summer both 'Tosca' and 'Lohengrin' were over twelve feet tall and at least six feet wide, overwhelming all their neighbors. So I cut them both down to 2' stumps with the intention of letting them grow back in a more controlled manner. 'Lohengrin' soon put out new growth and I now maintain it as a 5=6 foot sphere. The flowers are white with a red eye, and are much larger than either parent, rivaling the tropical H. rosa-sinensis in size. 'Lohengrin' is self-dead heading and it has never set seeds. Butterflies love it. Perhaps due to its herbaceous parent it starts blooming a week or more before H. syriacus and stays covered in flowers until the first frost.
