Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Jucara Palm or Euterpe edulis, otherwise known as jussara, acai-do-sul, or palmiteiro, is a tall, tropical palm tree primarily used for its palm heart. It grows usually about 10 m tall and 12 cm across. The trunk is light grey or brown in colour, and has prominent rings of leaf base scars. The leaves are dark green and have fine and feathery leaflets along the stalk. The fruits are small, round, and black to brown. Juice from the young stem is applied to wounds to stop bleeding. The leaves can be consumed raw or cooked. It is crunchy with a sweet flavour. The fruit has a thin, fleshy, fibrous pulp. It is made into a juice or ice cream. It can also be used to make alcohol or as a substitute to petrol. The wood is of low quality but can be used for rafters, beams, water troughs, and posts. A drink called Assai is obtained by crushing the seeds of Jucara palm. The unopened flower stalk is pickled. E. edulis is slow-growing.

A highly prized dish, often called 'Millionaires salad' due to its price[ 314 ]. The unexpanded leaves and bud from the crown of the plant are used[ 297 ]. Harvesting these leaves kills the plant because it is unable to make side-shoots[ 297 , 768 ]. Fruit - made into a juice[ 416 ]. The fruit has a thin, fleshy, fibrous pulp[ 416 ]. It is made into a high calorie juice[ 416 ]. The fruit is used for making a nutritious beverage or ice-cream[ 317 ]. The fruit is about 12mm in diameter[ 416 ].

Cultivation details

A plant of moist tropical and subtropical climates, where it is found at elevations from sea level to around 1,200 metres[ 418 ]. It grows in areas where the temperatures never fall below 10c, the average annual rainfall is 1,500mm or more and the driest month has 25mm or more rain[ 297 ]. Grows best in a warm, sheltered, and moist site that is well drained[ 314 ]. It likes filtered sunlight when young, but can take full sun as it matures[ 297 , 314 ]. Prefers a pH in the range 4.5 - 5, tolerating 4.1 - 5.6[ 418 ]. A fast-growing plant[ 200 ]. Utilizing the plant for its edible apical bud always leads to its eventual death since the palm is unable to form side branches and thus is unable to grow any more. This has led to plant populations coming under pressure in some areas[ 314 ]. Spacing: 6-8 ft. (1.8-2.4 m); 8-10 ft. (2.4-3 m); 10-12 ft. (3-3.6 m). They are grown commercially for palm hearts in Brazil.

Propagation

Seed - it has a short viability of less than three months and so is best sown as soon as it is ripe in a partially shaded position in a nursery seedbed. Pre-soak them in cold water for 24 hours prior to sowing[ 419 ]. A germination rate of around 80% or more can be expected, with the seed sprouting within 30 - 70 days[ 419 ]. The seed germinates rapidly and grows quickly[ 297 ].
