general - number of buds
During the winter dormant period it is usually possible to identify the buds/potential growing points of herbaceous perennials. These may be identified as follows:
Buds: These may develop to produce an inflorescence in the following growing season.
Axillary buds: These are growth buds; they are unlikely to produce inflorescences in the following growing season but will initiate the growth by which the clump increases in size.
