As shade plants (Skiadophyten) are plants called that only a subset of the usual amount of light need to their maximum photosynthesis to operate and therefore can grow in shady locations. The opposite are sun plants (heliophytes), whose need is higher and which show less growth in the shade or do not thrive at all.
Shade plants have thin, flat and often comparatively large leaves with plenty of chlorophyll, which maximizes the light yield.
A distinction is made between obligatory shade plants, which only thrive in the shade, and optional shade plants, which also grow in full sunlight, but here develop a sun shape.
Shade tolerant species are often also moisture-loving and often have large, thin leaves (hygromorphic) with loose, chlorophyll-rich tissue.
The locations are differentiated according to the amount of light:
- Negative ; usually refers to a location that is bright and not shielded from above - for example by a large treetop - but not directly illuminated by the sun. However, it benefits from an intense incidence of scattered light. However, one also speaks of a shady location if it is only protected from direct sun at noon.
- Light shade , light shade; when shadows and sunspots alternate on a small scale. Such locations are often found under very translucent tree tops, for example. A light-shaded location can also be exposed to full sun in the morning or evening - in contrast to the partially shaded location, however, it is not in full shade at any time of the day.
- Partial shade ; are locations that are temporarily in full shade - either in the morning and at noon, only during lunchtime or from noon to evening. They do not get more than four to six hours of sun a day and are usually not exposed to the midday sun.
- Shady ; are locations under large shrubs or trees also close to higher walls, buildings, with predominantly shade or partial shade.
