Outdoor flowers to decorate the garden
The choice of outdoor flowers, whether it is to embellish a balcony or a terrace, or to decorate a garden, is often very complicated: not because the range of options to make your selection is restricted, but on the contrary because it is necessary to reckon, as they say, with the embarrassment of choice, such and so many are the species on which it is possible to aim. It should be noted, moreover, that the flowers and plants must be cultivated taking into account, first of all, the sun's exposure to the soil or the balcony: since, in fact, there are plants that can withstand the sun's rays perfectly and plants that, on the other hand, tolerate the first temperature increases with difficulty, it is advisable to know in depth the flower for which one has opted. Of course, we must never forget that setting up a garden or decorating a balcony is above all a pleasure, and must not turn into an obligation or a task to be reluctantly respected. Much better, therefore, to let creativity and imagination flow freely, combining different colors and blooms according to your tastes, creating lively and chromatically spectacular compositions.
Flowers to be exposed to the sun
In particular, for terraces and balconies exposed to sunlight, the recommended outdoor flowers are the mini-surfinia (also called million bells), the angelonia, the diascia, the lobularia maritima (also known as the annual alyssum), the bidens, the argyranthemum, the lantana camara, the snapdragon, the brachycome iberidifolia, the euphorbia marginata, the convolvulus cneorum, the coreopsis, the convolvulus sabatius, the lavender, the lantana sellowiana, the lobelia, the laurentia axillaris, the star de oro, the geranium, the gazania, the gaillardia, the zinnia, the verbena, the plumbago, the African daisy, the petunia, the mesembryanthemum delosperma cooperi, the sanvitalia, the nasturtium, the thymophylla tenuiloba, the pentas lanceolata, the nicotiana, ornamental sage, portulaca and salvia splendens. It is important not to forget that, in order to bloom, seasonal plants need constant help, represented by a not excessive dose of manure, to be poured into the planters, and by specific liquid fertilizer for flowering plants to be used in the warm months. As for the leafy and accompanying plants that stand up well to the sun, we highlight the thyme, the cineraria maritima, the sedum, the dichondra argentea, the acorus ogon, the santolina, the American potato, the creeping name , muehlenbeckia, variegated carex, helichrysum petiolare and variegated ivy. On the other hand, for half-shaded soils and balconies, torenia, fuchsia, marigold, surfinia, variegated nasturtium, coleus, nemesia, mountain daisy, lobelia, campanula, are particularly indicated glass flowers, impatiens, heliotrope, chelone obliqua, begonia, agate, calceolaria, agatea and bacopa. Among the leaf and accompanying plants, on the other hand, it is worth mentioning the tradescantia (also known as zebrina), the hosta, the asparagus, the cineraria maritima, the begonia rex, the small hebe , the variegated liriope, the resin, the peperomia, the oxalis regnelli, the strobilanthes dyerianus, the lysimachia nummullaria aurea, the glechoma hederacea variegata, the lamium and the ophiopogon planiscapus.
It must be specified that the choice of flowers must be made after taking into consideration also the type of soil in which they will be destined to grow. In the case in which the cultivation in pot is privileged, there is no problem, in the sense that the single potting soil can be made more acidic or basic according to the needs, and enriched if necessary with nutrients. The situation of cultivation in open ground is different: in this case, in fact, we must not adapt the soil to the flowers, but the flowers to the ground. In short, we need to buy and plant only flowers that will be able to grow luxuriantly in those conditions.
Outdoor flowers: irrigation
Another aspect on which it is advisable to pay attention regards the administration of water: given that each plant shows specific needs, we must never forget a general rule, which applies to any species: and that is that it is better for flowers (but it is also worth for fat plants, bonsai, etc.), have less water than more water than necessary. Excessive irrigation, in fact, prevents the soil from draining as would be necessary, and therefore from making the water flow out; the risk is that water stagnations are formed that could give rise to unpleasant situations (for example, fungal infections caused by excessive humidity that risk damaging the roots of flowers causing rot). The problem is all the more accentuated in the flowers grown in plastic pots, while those located in terracotta pots can count on the high breathability guaranteed by this material, which favors a rather consistent evaporation.
Finally, a final aspect to consider is the possible attacks carried by insects and parasites: the action of red spider mites, cochineals and aphids can be counteracted simply by using specific anti-parasitic products, which can be found in any garden center. The whitish spots that these "enemies" might eventually leave, instead, can be removed with a solution of linseed oil.
