Abstract
Buddleja ‘Pink Micro Chip’ is a new and distinct variety of butterfly bush that has the following unique combination of desirable features that are outstanding in a new variety. ‘Pink Micro Chip’ has low vigor resulting in very dwarf stature. ‘Pink Micro Chip’ is asexually propagated using softwood or semi-hardwood cuttings. ‘Pink Micro Chip’ demonstrates a dense, spreading growth habit. ‘Pink Micro Chip’ is lacking male flower parts (anthers), resulting in male (pollen) sterility. ‘Pink Micro Chip’ produces female structures that are essentially sterile, resulting in lack of seed formation. ‘Pink Micro Chip’ has red-purple flower color.
