The oleander is native to Afghanistan and India, and has a long history in our country as well, being distributed in various regions. The oleander likes sunny, warm and humid environmental conditions. Its flower colors include red, white and yellow, etc. It is a cardiotonic type of traditional Chinese medicine, bitter in taste and cold in nature, and toxic. It can strengthen the heart and promote diuresis, eliminate phlegm and relieve asthma, relieve pain and remove blood stasis. It can be decocted into a medicinal soup for oral use, but the dosage must be paid attention to, between 0.3 grams and 0.9 grams.

✿Morphological Characteristics of Oleander
The oleander is an evergreen and upright large shrub, 5 m tall, with grayish-green branches containing watery sap. The young branches of the oleander are angular and covered with fine hairs, which fall off when old. The oleander has 3 to 4 whorled leaves, with the lower branches opposite and narrowly lanceolate, the apex extremely pointed, the leaf margin revolute, the base cuneate, the length between 11 cm and 15 cm, the width between 2 and 2.5 cm, the leaf surface dark green and hairless, and the leaf underside light green.

✿Oleander Cultivation and Management One.Timely pruning is necessary. The top branches of the oleander have the characteristic of one splitting into three, and it can be pruned and shaped according to one's own needs, for example into the three-fork nine-top shape and the nine-top eighteen-branch shape, etc. The pruning time should be arranged after each flowering. In the north, the flowering period of the oleander is from April to October. Faded flowers should be picked off in time to ensure the concentration of nutrients. The oleander is pruned four times: the first time after Grain Rain in spring, the second time in July to August, the third time in October, and the fourth time is winter pruning.

Two.Root thinning must be done in time. The capillary roots of the oleander grow very quickly. Too many roots will form a ball, which not only hinders the absorption of water and fertilizer but also affects growth. If root thinning is not carried out in time, conditions such as withering, leaf drop and death will occur. The best time for root thinning is from early August to late September, when the roots of the oleander have already gone dormant, making it a good opportunity for root thinning. After root thinning, remember to place it in the shade and water it thoroughly, keeping the potting soil moist.

Three.Timely topdressing and watering are necessary. The oleander is a flower that likes fertilizer and water and likes neutral and slightly acidic soil. When fertilizing, about 20% organic soil manure should be maintained in the potting soil. The fertilizing time is once before Qingming and once after the Autumn Equinox. Proper watering is the key to managing the oleander well. Improper watering in winter and summer will cause leaf drop, flower drop and even death. In spring, water once a day; in summer, water once each morning and evening, and the leaves should be sprayed with water frequently to keep them moist.

Conclusion:The oleander is a perennial herbaceous plant with great medicinal value, but it must never be taken orally directly, because its toxicity is very strong. The above is a simple introduction to the oleander picture appreciation, morphological characteristics and cultivation management shared by the editor today. I hope it can be of some help to friends.

The oleander belongs to the genus Nerium in the family Apocynaceae, also known as willow-leaf peach. The oleander is an evergreen shrub or small tree, with a plant height of 2 to 6 m, single leaves whorled, leathery and glossy, leaves lanceolate, with margins slightly revolute. Terminal cymes, corolla funnel-shaped, red or white, single or double, flower diameter 4 to 5 cm, fragrant. The flowering period is from June to September, and the fruit ripens in December.
The oleander likes a sunny, warm and humid environment. Although it is not cold-resistant, it has strong adaptability. It can be cultivated in the open ground in central and eastern China. The oleander is not strict about soil and can adapt to slightly acidic and slightly alkaline soil,
but loose and fertile soil is suitable. For pot cultivation, the potting soil is best mixed with 3 parts leaf mold or 3 parts compost soil, 3 parts dried manure soil and 4 parts sandy soil. The oleander grows fast, so the pot should be changed once every year when it is moved outdoors in late April. In addition to changing the potting soil, a small amount of hoof and horn should also be applied as base fertilizer. From moving the potted oleander outdoors until the flowers fade in September to October, a dry fertilizer of fermented sesame paste residue should be applied once a month. The application amount depends on the size of the pot. For example, a 20 cm pot uses 50 grams, and a 50 cm pot uses 200 grams. For pot cultivation, water thoroughly whenever the soil looks dry. If the potting soil is too dry and the leaves have already shown wilting, first water lightly, and after the leaves recover, water thoroughly.
Potted oleander should be shaped and pruned once a year. When pruning, generally 3 main branches are retained on each main trunk, and 3 branches are retained on each main branch. Each branch should be cut at 20 to 30 cm from the base. This is the commonly used "three-fork nine-top" shaping and pruning method. This method will also make its flowering branches cover the whole plant.
The oleander propagates easily and can be cuttings in spring and summer. The cuttings do not need to carry leaves. High-temperature and high-humidity aerial propagation can also be used. It roots easily, but after rooting, transplanting must be done carefully, otherwise the roots are easily damaged. In addition, there is also the water cuttings method, that is, inserting leafy branches into water, and both rooting and transplanting are very easy. If large-scale propagation is not needed, the division propagation method can be adopted.
