Trees choice

Question: choice of trees

hi expert thank you in advance. I have a small garden of about 5 square meters in front of the house, facing north, with frost and cold winds. In winter it is not affected even by the smallest ray of light. Instead in summer it is hit by light rays for about 3 hours. In addition, there is a low wall less than a meter high that creates more shade at the bottom. Here there are 2 hollies and a lilac ... but the holly I cut them leaving only the lilac. Now the garden seems more bare. would you be able to tell me magnificent plants that make beautiful flowers that are good for these conditions that I have written above and that are not made more than 2 meters high? Thanks so much

Answer: choice of trees

Dear Antonio,
shaded flowerbeds are often difficult to cultivate, especially when the wind is associated with shade; in addition to the climatic conditions, the shadow in general is not indicated for many flowering plants, since without direct sunlight many plants struggle to bloom, and therefore lose most of their beauty.
If in the garden, however, you are already successfully cultivating a lilac, I believe that the shadow you are talking about is still quite bright, not a gloomy and dark shadow.
Typically, in shaded flowerbeds, acidophilic plants are planted because they fear intense heat and strong summer and late spring insolations; they are therefore better in the shade, rather than exposed to the hot June sun.
Acidophilous plants are many, and all beautiful: camellias, azaleas, pieris, leucothoe, kalmie, rhododendrons, all buckets, evergreens (or evergreen seeds), with a beautiful flowering.
Obviously they need specific soil for acidophilic plants, so to plant them you will have to prepare a large planting hole, which will be filled with a little manure and a lot of peat, or with ready-made soil, specific for acidophilic plants. These plants do not like that in the soil there is a high amount of calcium, so over time they need greening fertilizers, since the aqueduct water is often rich in limestone, which is deposited in the ground, raising its pH. Apart from this problem related to the soil, acidophilic plants are not difficult to cultivate: they prefer a fresh and damp, but not soaked soil; they must be fertilized at the end of winter with special fertilizers; they have a beautiful flowering, which in the case of hydrangeas is continuous throughout the summer.
At the foot of these shrubs, especially the tall ones, you can place hosta, ophiopogon, or other perennials that tolerate the shade; in fact, often among the perennials we find small ground cover, which we could almost call alpine, as they do not like the heat and the summer drought: they are perfect plants for the shaded flower beds, where they thrive without problems.
Even some roses seem to resist in the shaded flowerbeds, even if you don't always get amazing successes, since most of the roses, especially modern hybrids, need at least a few hours of direct sun to be able to bloom abundantly; and a shrub of roses completely without flowers is not particularly decorative in the garden.
Among the most famous shade roses, surely the wrinkled ones are the most known, they have well light foliage, and large and showy flowers; also the banksiae roses are suitable for shade, they are climbing plants, and they bloom only once in early spring, with a cascade of small white or yellow flowers.
