Prunus dulcis Princesse - Almond Tree

Prunus dulcis 'Princess' is also known as the pistachio almond tree due to its slightly unique flavour. The shell of the nut is so tender that it bursts under finger pressure, revealing the fragrant white flesh of the sweet nut. The harvest takes place in September. Plant your tree in autumn.

Prunus dulcis and its varieties belong to the Rosaceae family. It is native to central Asia, but has become typical of the Mediterranean region. Its deciduous leaves are alternate, narrow, and lanceolate. It will reach a height of 6 to 10m (20 to 33ft) with a width of 5 to 8m (16 to 26ft). It can live for several decades. It is very hardy, able to withstand temperatures of -20°C (-4°F), but its flowers are destroyed at -2°C (28.4°F). It can be planted in a fruit or ornamental garden, thanks to its beautiful flowering that appears in late winter.

'Princess' flowers in March. It is sensitive to spring frosts. In cold regions, plant 'Princess' with the shelter of a wall and a favourable exposure. Partially self-fertile, it will be more productive in the presence of another variety, such as 'Texas', which is a good pollinator.

The almond is actually the inside of the seed. A shell protects this almond, which is itself contained in a fuzzy envelope that opens when ripe. For harvesting, the shells are collected on the ground. The branches can be shaken to loosen the nuts. They are then dried, spread out in the sun, and left for several days. Once dry, the almonds can be stored for several months in a dry and well-ventilated place. In May and June, it is also possible to pick fresh (green) almonds by hand. These will keep for just a few days. Almonds can be cooked with their skin, blanched (without the skin), sliced, or crushed. They are mainly consumed in desserts or in savoury dishes such as tagines, for example. They are an oily fruit, which can sometimes cause allergic reactions.
