Herbaceous Plants – Summary

This table gives information typically used in the specification of herbaceous plants. It is important to realise that plants are variable and growth varies between species and seasons.  For this reason, the details within the table give general, accepted dimensions and terms for the specification of herbaceous plants but there are always well grown and healthy plants which are exceptions.  A knowledge of the product and its production methods are important factors when specifying plants.

Values shown in bold type indicate the more typical for the range.
