Garden plants with flowers
Generally the various species belong to the great genus of the angiosperms and have an ancient origin, dating back to the Cretaceous era. The characteristic of this type of plant is precisely the flower, which differentiates it from plants that produce only seeds, or gymnosperms. They have succeeded in spreading exponentially thanks to their resistance and their ability to adapt to the different climates of the geographical areas. Angiosperms are the most widespread in nature also because they have a shorter fertilization period than gymnosperms. Depending on the variety, they can be divided into large groups, including the woody types of the Austrobaileyales, the Nymphaeales with more than ninety species and the Amborella shrub. In addition to these, there is the very large group of Magnolidaeas, which include, for example, laurel and magnolia, although their total number far exceeds the ten thousand species. Other aromatic flowering plants are known as Chloranthales. All plant species with flowers are subject to the same diseases, to which particular attention should be paid. It will first of all be a good thing to prevent the process of stagnation of liquids on the roots and on the stems avoiding an excessive administration of water and the consequent process of marking; if this is already in progress, specific fungicides should be used. The ideal soil for planting the plants must therefore be moist, rich in nutrients and well drained. Another pathology worthy of attention is that caused by the fungus of the oido, which usually affects the small buds and tender leaves, leaving on them a whitish patina; also in this case the best remedy is a good fungicide, to be administered however, in a preventive measure, at the beginning of the spring season.
The Weigelia
Weigelia is a shrub native to the Asian continent and belonging to the coprifoliaceae family. The flowers, bright pink on the outside and milky white on the inside, are bell-shaped and are born on the top of the new twigs at the beginning of the spring season. This flowering plant needs a lot of space to be able to develop in all its beauty, since it can reach up to four meters in height. Its ideal arrangement is in an area exposed to direct sunlight. Being a rather resistant species, it will adapt to the various types of climate present in the geographical area where it will be cultivated. Despite this, great attention must be paid to the quality of the soil, which must always be kept well drained and moist; it is therefore advisable to water it on a regular basis, especially in the summer season, when the water evaporates faster. Once a year the Weigelia will be properly pruned, removing the dry or rotten twigs and adjusting the crown. The soil, in addition to being damp, must be enriched with precious nutrients, made for example by fertilizing with mature manure or specific humus, at least once a year, and always in the spring season. As for watering, a weekly administration will be fine, doubled if the temperature is very high. The multiplication is carried out by means of cuttings: to proceed, one must cut one on the side of the plant, so as not to affect the flowering, then transplant it into a soil to which a fair amount of fresh soil and sand in parts will have been added equal. The definitive planting, whether in the garden or in a pot, should be performed only in the spring season.
The Cobea Scadens and the Cyclamen
The Cobea Scadens, native to Mexico and belonging to the Poliomenacee, is a climber with flowers that reaches important heights, even up to more than twelve meters; for this reason it needs sufficient space. It has very beautiful and decorative flowers, in shades ranging from violet, lilac and blue to the evocative dark blue. In addition to its ornamental use, especially as a hedge, it is a highly coveted and sought-after plant for flower arrangements. The ideal arrangement is in half shade, since the delicate flowers suffer from the too intense light of the sun, especially in the central hours of the day. Despite being a shrub, the Cobea is not very resistant, and it also suffers from the harsh climate and winter frosts. The soil must be moist and well drained, so as to allow the roots to absorb all the nutrients. As for watering, it will need one every ten days if the temperature is mild or cold and up to three in a week in the summer season. The leaves and the sprouts must be checked constantly to be able to intervene in time with insecticides in the case of aphids. The cyclamen is a widespread plant thanks to its versatility that allows it to grow without problems both in the garden and in the apartment. The flowers are of different shades ranging from white, red, pink and ivory. Each flower is composed of five petals, which take on a graceful heart shape. The cyclamen has a very long flowering, which begins in winter and ends in late spring. The garden plant should be placed in the shade and planted at the beginning of the spring season. It does not require frequent watering, a weekly administration in summer and one every fifteen to twenty days in winter will suffice. The cyclamen is rather reluctant to get sick, however it is a good idea to use an insecticide at least once a year, preferably in spring.
The Orchid
The Orchid plant boasts numerous species and is native to the tropical areas of Asia. The symbolism of the flower has very ancient origins and represents sensuality, elegance and refinement. It has a flower with a very particular shape with a three-petal calyx. Depending on the species, the colors vary from milk white, ivory, yellow and shades of violet, while the leaves, of a bright green, are elongated. The Orchid is unfortunately very delicate and needs special and careful care. The ideal arrangement for optimal growth is in a well-lit area of the garden, but not directly exposed to sunlight, while bearing in mind that the plant does not withstand torrid climates or excessively freezing temperatures. Especially in the hottest times of the year, it should be abundantly watered, even with four weekly sessions, taking care not to use the direct jet of water to not ruin the flowers and the new buds. The soil must be adequately drained and enriched with precious nutrients, made with a potassium and nitrogen based fertilizer, increasing it if possible with small pieces of crumbled bark and pine needles. The Orchid also fears the stagnation of liquids, since it tends to rot easily, given the softness of the stem: it is therefore necessary to avoid over-watering the plant and it is advisable at the same time to carry out regular sprays of fungicides.
