general - bare root shrubs - root balled shrubs - cell grown shrubs - container grown shrubs (height) - container grown shrubs (spread)
The overall height and/or spread, at the time of sale, is significant in the specification of shrubs, although this is now additionally qualified by reference to the number of branches (or breaks) which is to be expected for the plant of that size. Shrubs vary from compact, slow growing species, to low forms, through medium size types to vigorous, fast growing species and it is important to specify appropriately for each type.
The use of height and/or spread dimensions depends on the characteristics of the species and the dimensions which are most appropriate at the time of sale. The following tables give information about the general grades for shrubs in cultivation.
Shrubs are available bare root, rootballed, cell grown or container grown.
