Relating to or having the characteristics of herbs; (of plants) having green, soft stems that die back each year rather than woody stems.
From Latin 'herbaceus' (grassy), derived from 'herba' (herb) with the suffix '-aceous' (from Latin '-aceus'), meaning 'of the nature of' or 'resembling.'
Herbaceous plants are soft and green—they die every winter—while woody plants like trees are permanent, which is why your garden flowers aren't the same type as an oak tree.
