Evergreen planters

Answer: what plants should I put in my planters?

SOS. My husband and I are building a house in Tarquinia ... you know, architects sometimes have strange ideas, and ours wanted to include three planters in the structure of the house and here the problem arises ... they are practically unreachable so I wondered what type of evergreens we could plant?

Evergreen planters: Answer: planter evergreens

Dear Simonetta,
the choice of evergreen plants to place in your planters depends on a number of factors: the size of the planters themselves, positioning, the presence of water drain holes. Given that the house is located in an area of ‚Äč‚ÄčItaly with fairly mild winters, in your planters you could find any small garden shrubs, only if, if the planters are not very roomy, or if they are positioned in full sun for many hours days, and therefore it becomes difficult to water the plants, I believe that dryness and desiccation can always be lurking. If, on the other hand, it is possible to install a drip irrigation system in planters, you can plant small viburnum, or pyracanhta or cotonastri, even in dwarf varieties, which tend not to become intrusive; if the planters can be watered, but they are in the shade or in partial shade, you can place azaleas, or small rhododendrons, also in this case choosing the dwarf varieties, so that over the years it does not become necessary to prune the shrubs.
If, on the other hand, the planters are always in the sun, of small dimensions, and it is not possible to place an irrigation system in them, I think it is necessary to use them only for succulent plants, which can survive long hot and dry seasons; the only plants that can survive in such conditions are the sempervivum, or the aptenia: plants with succulent leaves, which hold water, so as to use it at the arrival of summer, when the rains no longer provide watering.
If the planters are very large, a large agave can also be placed, which does not fear drought, nor even the winter cold of Tarquinia.
