Herbaceous plants are not woody. Their stems are soft, usually remaining green. With some herabceous older stems may harden and look like woody stems (e. g. bamboo).

Leaves or needles remain on the plant throughout the winter and fall down in spring when new ones emerge. Part of leaves or needles may fall already in autumn or winter. The falling off depends on winter temperature, so some plants are evergreen in mild winter, yet decidous in cold winter
