Amarillis

Characteristics of the plant

Amarillis are plants of South African origin, particularly widespread also in European gardens due to their original appearance, which makes them highly attractive elements capable of giving personality to any space. Although it is not a plant with a particularly intense scent, in fact, amarillis is able to immediately strike the eye thanks to the bright colors of its flowers. Given its origin, it is not surprising that amarillis, also known as Hippeastrum, prefers well-lit places, although it is advisable to avoid direct exposure to sunlight. Due to the high temperatures that it needs to grow and develop, amarillis is also well suited to cultivation in the apartment, in which it will constitute an element with small dimensions but of great visual impact. Depending on the type of plant chosen, the color of the flowers may vary between different shades of pink and single-color or two-color orange. The shape of the flowers is also subject to variations depending on the variety. The cybster, for example, has very particular flowers, composed of dark-colored ribbon-like petals. The bulbs give life to plants between 40 and 60 cm tall. The main peculiarity of the amarillis is not only in the bright colors, but also in the size of the flowers: in healthy and luxuriant specimens, grown in an optimal way, they can reach up to 15 cm in diameter. it has very particular flowers, composed of ribbon-like petals of dark color.

Fertilization and pruning


Amarillis, as seen, prefer dry and not too humid soils, therefore they require regular but never excessive pruning, without stagnation of water. This does not mean, of course, that the quality of the soil is not important: on the contrary, the soil that houses the bulb must be subjected to fertilization with specific products in the spring, while this operation may be suspended in the cold months, when the development of the plant will be slowed down. Amarillis does not require special pruning operations: they can be limited to the removal of any dry leaves, to improve the health of the plant and also its visual impact, in the autumn period. The leaves will be cut 3 – 5 cm from the bulb. Following the flowering period, which occurs in succession, it is advisable to also eliminate the flowers by now withered, as well as the floral stem once there are no more flowers on it. Amarillis hippaestrum should not be confused with amarillis belladonna, which suffer much less from the cold and can therefore be grown in the garden: the flowers of this variety of amarillis are smaller in size. Also in this case, in the cold months it will be possible to suspend fertilization.

Diseases and parasites


Amarillis are plants resistant to attacks by parasites and fungi; the main danger is therefore constituted by excessive watering, which could cause stagnation and therefore the rotting of the roots and the bulb, in an irreparable and lethal way for the plant. Among the fungal diseases, the most common enemy for amarillis is instead the Stagonospora Curtisii, which manifests itself through the presence of red spots, initially small and widespread only on the bulb and on the basal part of the plant, and must be treated with a specific pesticide. A further form of safety is given by formalin, with which it is possible to disinfect the bulb before it is placed in the ground. In this way the bulb will be more protected even from the attack of small insects. The amarillis grown in open they should be protected from snails, which could devour the leaves. Against the attack of small spiders it is good to protect the plant with insecticides, in such a way as to neutralize even the spider mite, mite that can affect the plant making its leaves yellow. Against the presence of mites, especially if the plant is in an apartment, it is possible to increase the ambient humidity, since they mainly proliferate in dry environments.
