To the genus nyssa belong some deciduous trees, widespread in North America, among which also the nyssa sylvatica, cultivated as an ornamental also in our gardens. These are medium-sized trees, with slow growth, which can easily reach 15-20 meters in height; they have erect stems, and very dense and articulated branches; the crown is pyramidal in young specimens, with time it tends to become oval or roundish, with low branches reaching almost to the ground. The foliage is oval, shiny and slightly leathery; the young leaves are reddish-green, becoming a beautiful dark green color. In autumn, before falling, the leaves take on a very intense orange color.
The trees and specimens of Nyssa sylvatica are suitable to be planted in a sunny place, or even partially shady. They are plants that do not fear the cold, even if intense and grow well almost everywhere. Rustic and luxuriant, they are ideal both as single trees and as trees, the latter being used to greatly enhance the plant in the winter months when the leaves blush, creating very pleasant chromatic effects. During the autumn season, in fact, the leaves of the plant begin to show splendid orange-reddish colors, particularly suitable for embellishing the garden and making it unique.
During the winter season, this species can withstand temperatures between -20 ° and -14 degrees.
Watering the plant is not an operation to be performed with particular frequency.
The adult trees are satisfied with the rains while the specimens recently placed at home may need watering in case of prolonged periods of drought. They endure very wet or dry periods very well, but if prolonged these conditions can put a lot of problems on the plant and trigger processes of deterioration. We therefore try to plant the nyssa sylvatica in areas where the climate is ideal for its real needs.
The nyssa prefer soft and quite drained, deep soils; it is advisable to place these trees in a location with neutral or slightly acid soil. The best soil typology for the optimal development of Nyssa sylvatica can however be called "variable". In fact, the best subrato varies from the chalky, fat, clayey to the totally sandy while the soil ph can be neutral, acid or alkaline.
The multiplication of the nyssa sylvatica it happens by seed, in spring. Semi-woody cuttings can also be prepared, but they do not take root very easily. For seed multiplication it is always advisable to use a seedbed in which to cultivate the seedlings in the initial phase of germination, and then transfer them to a larger, even definitive, vessel. Nyssa trees are dioecious, so we will have male trees and female trees; in effect, however, all nyssa sylvatica trees have some both male and female flowers, so they all produce fruits; predominantly female trees produce very many fruits, the majority of which are very few. The fruits are similar to olives, of black or bluish color, they are edible, although not particularly pleasant to the taste.
Nyssa sylvatica: Parasites and diseases
These species do not generally present parasites and do not show particular diseases. They are in fact fairly robust plants that are generally not damaged by pests. Trees planted in very basic soil can have stunted growth and be perishable but there are no particular diseases that constantly and repetitively affect this plant, perhaps even due to the small number of specimens present in our country.
So if you want to cultivate a species without particular cultivation requirements and able to make the home garden a pleasant and beautiful place to live, the nyssa represents the most suitable variety for you!
