Plants for shade


Question: which plants to place in the shelter of a porch?


Having learned that the viburnum requires direct exposure to the sun, I would like to have, as a courtesy, a suggestion for a green plant to be placed in a rectangular pot outside under a portico, which would take up sun indirectly. Thanks. Sincerely.

Plants for shade: Answer: plants that love shade


Dear Thomas,
it is true that the sheltered positions of a porch can cause some problems to plants that need direct sunlight for many hours a day; It is also true, however, that we can take advantage of this position for those plants that would find the garden too hot and sunny.
Even the cultivation in pots is often seen as a useless compulsion, in reality it helps us with those plants that are a bit difficult, requiring particular soil: if we grow them in pots, we can easily change the earth, even every year, in an attempt to maintain it always perfect.
In general, then, I think your porch can also be quite bright, even if it is not hit directly by the sun's rays.
Surely, in the areas in half-shade and in pots, I think it would be appropriate to place a beautiful acidophilous plant: in this way you will be able to continuously monitor the ph of the substrate contained in the pot, and change it every two or three years, if it becomes excessively alkaline.
So rhododendrons, azaleas, hydrangeas, pieris, sarcococche; they are all plants that prefer positions that are not too sunny, cool and humid, with acid soil.
Also camellias often have a better development if placed in semi-shaded places; the protection of the porch then, will help you in those years with very cold and long winters, which often almost completely ruin the camellia buds.
Then there are typical shadow plants, such as the aucuba, often available in varieties with particular variegated foliage, streaked or dotted, which can also revive the thickest shade.
Astilbe and hosta are lively perennial plants, which often disappear completely during the winter, to give us large decorative leaves and even flowers in spring.
If the vase in which you want to keep the plant is not small, but it is a beautiful bathtub, you can think of planting a Japanese maple, or a cornus florida: they are plants that often suffer in the long Italian summers if they are not refreshed by the irrigation system, or from providential rains; your porch will provide them with a corner away from the scorching sun.
I remind you that often plants that like shade or partial shade also like fresh soil and regular watering; unfortunately your potted plant, being sheltered from the porch, will not receive the rain water; therefore you will have to water the plant of your choice on a regular basis, but always waiting for the soil to dry before watering again.
