▷ Albizia julibrissin: the tree with feathered flowers

Pink feathery tufts fluctuate following the rhythm of a melody, dictated by the wind. Take a seat in the shade of an Albizia and experience the lightness of the moment.

ETYMOLOGY

The mimosa tree (Albizia julibrissin) has many other names. The most common are Persian silk tree, Constantinople golden acacia, Gaggia arborea, and Rosa siris. Other names include Lencolan golden acacia and hybrid tamarind.

There are also some more general, and sometimes misleading, names such as Chinese silk tree, silk tree, and mimosa.

However, names associated with the plant’s peculiar habit of slowly closing its leaves at night or during the rainy season are particularly interesting. For example, the Persian word “shabkhosb” means “to sleep,” the Chinese word “” (literally “to close happily”) symbolizes a happy couple lying in bed, and the Japanese words “nemunoki,” “nemurinoki,” and “nenenoki” all mean “sleeping tree.”

TAXONOMY

It is part of the Fabaceae family.

The genus Albizia includes approximately 150 species of deciduous trees, bushes and climbers, often located in areas with poor soils in tropical and subtropical areas of Africa, Asia and Australia.

They are plants generally cultivated for their high ornamental value given by the foliage and fan-shaped flowers, which are very particular and decorative.

MORPHOLOGICAL DESCRIPTION

The mimosa (Albizia julibrissin) is a fast-growing but relatively small tree, reaching a height of 5-12 meters.

The bark is light gray with light-colored vertical stripes that gradually become more prominent as the tree grows.

The leaves are 20-45 cm long and 12-25 cm wide, bipinnate compound leaves, and a beautiful light green color. As mentioned earlier, the leaves close like a book during nighttime rain or insufficient sunlight.

The mimosa blooms throughout the summer, attracting many visitors. The white and pink stamens on the inflorescence are particularly striking. Bees, butterflies, and hummingbirds are very fond of this flower.

After flowering, a green pod about 10-20 cm long develops.

HABITAT

Albizia julibrissin is native to Iran, Azerbaijan, China and Korea.

However, it is also planted and grows without problems in California, Texas and Oklahoma.

CARE AND CULTIVATION

TEMPERATURE

it is very resistant to frost, and can even withstand temperatures of -20°C. However, it does not like cold winds.

EXPOSURE

Loves direct exposure to the sun. It also tolerates partial shade conditions but the blooms will not be able to express themselves at their best.

WATERING

It is drought tolerant, but without water the tree will start to look quite sickly. In the case of a young plant, it will need regularly irrigated soil, in order to keep the soil moist, while for adult specimens rainfall is usually sufficient, in case of dry periods it is advisable to water manually.

SUBSTRATE

It does not have great demands on the soil, tolerates a wide range of conditions, including poor or alkaline soils. However, with well-draining and fertile soil it will develop much better 😉

FERTILIZER

From spring to autumn it is possible to administer a granular fertilizer once a month, in case of a prompt effect. However, if you prefer a slow release fertilizer, 3 fertilizations will be enough: one in March, one in June and one in September.

PRUNING

Between January and February it is possible to proceed with pruning which aims to give the desired shape to the plant, be it an inverted cone, a small tree or simply or to contain its size.

Pruning must be done rather delicately.
