Botanical description
Habitus: Black locust has a shallow root system, the main vein develops numerous side veins that can be up to 20 meters long. It grows up to meters in height, and the trunk is up to 50 meters in diameter. The crown is branched and sparse, while the branches are thorny, mostly winding.
Flower: Its flowers are fragrant, have short stems and grow in bunches. The calyx is light green, bell-shaped and covered with hairs. It consists of 5 fused leaves, while the wreath is up to 2 cm long and made of white petals with a flag that has a yellow spot. The anthers have fused together into a tube, 9 of them, while one anther is free, the carpel has grown. The fruits are pendulous, flat pods 5-10 cm long, each containing 5-10 kidney shaped brown seeds. Individual pods remain hanging on the tree through the winter.
Leaves: leaves are 15-30 cm long, compound, oddly pinnate and located on a very short stem.
Growth conditions / Cultivation / Care
Locust grows on dry, moderately moist and sandy soils. Good drainage is the most important thing for acacia, because it cannot tolerate water-retaining, compacted and eroded soils. It grows in areas with moderately moist soils, but can tolerate climates with less precipitation and mountain and lowland climatic zones. It needs a lot of sun, it does not tolerate shade.

Use / Function and landscape
Solitary planting
Planting in groups
For tree rows
A fruit with an interesting shape for arranging
Afforestation due to the rapid growth of seedlings
Honey plant
It can be planted to fertilize the soil because it binds nitrogen in the soil with its roots
Special use
Leaves and flowers are harvested – when consuming the leaves, be careful not to consume too large quantities, the leaves can be breaded (they taste like breaded zucchini)
The flowers contain vitamin C, they are used to make marmalade and wine
Locust seeds are also edible, they are rich in proteins, they need to be boiled before consumption, after which they are fried and used as a substitute for coffee.
Reproduction
Locust spreads vegetatively, i.e. by shoots or underground shoots. It can also reproduce by generative means. For planting a single tree, the easiest way to propagate acacia is by cuttings.
