It has an erect habit, poorly branched; the bark is gray, rough and covered with deep veins; the branches carry numerous sharp thorns. The foliage tends to spread like an umbrella; the leaves are dark green, pinnate, consisting of small oval or lanceolate leaflets. In late summer it produces large panicles of white flowers, followed by small purple or pink fruits, which remain on the plant for weeks. Before falling, the leaves turn yellow or reddish.
Regarding the exposure, the species of angelica of Japan are cultivated in a semi-shaded position, even if they do not show big problems in full sun and can grow without particular cultivation needs; moreover, these trees do not fear the cold; in regions with very hot summers it is advisable to cultivate the plant in a semi-shaded place to prevent the plant from showing signs of weakness at the time of development.
There are some very elegant cultivars with variegated foliage of white or yellow. These small trees have a very delicate appearance and are very decorative, unfortunately they are not very easy to find on the market, but are increasingly appreciated by landscape architects.

Depending on the type of soil, plants can grow and develop at their best, or show signs of weakness and in the most extreme cases these conditions will lead to the death of our plant. It is therefore good to know the characteristics of the species we intend to cultivate and what is the ideal soil.
The aralia love loose and rich soils, slightly acidic and moist, but very well drained, with no water stagnation. They can therefore grow in any soil, as long as it is well drained.
As far as fertilization is concerned, this must be done during the spring and autumn seasons. The organic fertilizer will serve our plant to develop at best and to avoid at least in part, the attack of pests and the development of disease because once fertilized, the plant will be stronger, stronger and vigorous.
For lovers of this species, it is good to know that the plant can be reproduced in a simple way and it is possible to obtain new plants to grow. There aralia elata It is in fact an excellent ornamental plant and for those who possess the famous "green thumb", multiplying this particular species could be a fun pastime and at the same time, a hobby capable of giving great satisfaction.
