Weeping growth habit is a genetically controlled trait, usually caused by single gene mutations. These mutations impact the normal response of the plant to gravity, called the geotropic response, resulting in weeping rather than upright branching.
Weeping plant forms provide a distinct architectural element to the landscape. They are sometimes grafted high (4'-6') onto an upright rootstock to accentuate and showcase the graceful, arching form. This form can be an excellent choice for small landscapes due to its reduced size and four-season appeal.
