Selection and allocation of shade plants in courtyard

In the courtyard, it is dark, damp and shady when it is obscured by tall courtyard trees, and these places can hardly get the sun, and it is often the place where plants do not like to stay. So in the plant configuration, we should choose some shady plants that like to grow in the shade.

Shade plants refer to plants that have strong tolerance to shade and can grow in shade. The shade tree has the nature of shade plant when it is young, and the better the growth condition is, the more obvious the shade plant is. The leaf respiration of shade plants is small, and the net assimilation of leaves of shade plants is greater than that of sun plants under low light (illuminance below 1000 lux). The arrangement of leaves is flat and mosaic at the same time, so the material production is large in low light. However, because the cuticle of the leaves is thin and the resistance to drying is weak, the typical shade plants (especially skiophyte) can not grow under direct light (such as Corydalis). But many plants that grow in the shade can grow under oblique light. This kind of plant, which has intermediate properties with solar plants, is called shade-positive plants (skio-hel-iophyte).

The common shade plants in the courtyard are: Brazilian iron, green basket, tortoise back bamboo, green overlord, rich bamboo, rich tree, money tree, lily bamboo; shade-tolerant orchids, bananas, taros, sunflowers; Alsophila spinulosa, iron ferns, Boston ferns, staghorn ferns and other ferns; vines have firecrackers, night incense, wisteria, rhododendron, green pineapple.

Selection of shade plants

The corresponding shade plants can be selected in different shady environments of the courtyard, such as ferns, Polygonum multiflorum, Ruo bamboo, etc., and shade-tolerant and flowering species can be selected in the semi-shade. Such as eight immortal flowers, lilies, bluebells, Bletilla striata, day lilies, garlic, hairpin and so on.

Configuration of shade plants

It should be artistic in plant configuration, fully highlight the bright color and hierarchical sense of courtyard plants, and plant some shady plants that change in four seasons, which can interplant shrubs such as camellia and rhododendron under tall deciduous trees, and perennial herbs can be arranged under shrubs. Autumn is the best time to plant spring flower bulbs, you can plant them all over the place, or you can plant them naturally from the ground. Spring flower bulbs will make use of the deciduous period of trees to grow rapidly in the sun, fully display their green leaf color, and have a high ornamental value in the coming spring. Spring flowers can plant plants that grow in summer, and there are many kinds of plants in summer, such as tobacco, clematis, Rehmannia glutinosa and so on. When summer turns to autumn, color-leaf ornamental plants and fruit plants also enter the ornamental period, many of which can be maintained until winter and are also pleasing to the eye after frost, such as purple plants, southern bamboos, firethorns and so on.
