Plants for partial shade need a few hours of direct sun per day to grow and blossom properly, thus could suffer harm from direct sun heat or overlong sun exposure. It is important for the plant not to be exposed to afternoon heat and in early afternoon hours, but must be exposed to morning, forenoon and evening sun. Partial shadow position can mean a site that is sunny one part of the day, or a site with sun and shade in patches, as it is the case under broadlived trees or behind a picket fence - wooden boards with spaces in between.

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 for several consecutive years, usually 2 to 5 years. Our descriptions contain the word evergreen.

Plant can in otherwise appropriate environment survive cold down to - 23 °C.

Wet soils are normally heavier, loamy or even clay, also peat soil and soil rich in humus, soil by watercourses and on swampy terrain. These are mostly less airy or even not airy enoguh for most plants, they are always wet or even saturated with water; water stagnates, only slowly flows away. Plants of such undergrowth do not tolerate drought, in neccessary need of permanent moisture, tolerate inundation, some can grow in shallow water (up to 5 cm in depth) or in garden bed, when watered regularly.

Herbaceous, not woody plant. Stems and leaves may be evergreen or deciduous - thus regrowing every spring. Perennials may blossom consecutively for several years. Some perennials develop special underground organs - bulbs, corms or rootstocks and these species are treated separetelly, not with geophyte and tuberous plants.
