Vitellaria paradoxa (Shea Tree)


Michael's Opinion

Shea trees thrive in some of the harshest driest climates in the world while still being an outstanding resource economically because of its commercial use, as well as medicinally because of their oils full of antioxidants and fatty acids. Due to its sturdy termite resistant wood, it can also be used as a long lasting building material. A huge beautiful tree like this not only provides so much for the people who harvest it, but also improves the soil quality and overall fertility of its surrounding grounds.

Description and Growing Information

General DescriptionA large deciduous tree with long wavy green leaves, rounded green fruits and white flowers.
ID CharacteristicOblong green leaves with wavy edges. Clusters of green fruits. White hermaphroditic flowers.
ShapeUpright with a large wide spreading multi branched crown.
LandscapeThe shea tree is a highly respected tree in Sub-Saharan Africa because of all of its benefits to the soils surrounding it and benefits medicinally and commercially. Vitellaria paradoxa is so well respected that farmers, landscapers and urban planners will make efforts to preserve the tree if it is on the land being used. There are many commercial uses for the Shea tree making it a high source of income for many growers. Commercial uses for shea butter (oil derived from the nuts of the shee fruit) are extensive because it is rich in antioxidants and fatty acids making it a staple in beauty products and topical medicine, it can also be used for cooking oil and as a substitute for cocoa butter in baking. The termite resistant wood of the Vitellaria paradoxa is also used in construction and for latex. Vitellaria paradoxa also has incredible benefits to the soils and areas surrounding it wherever it grows by improving the microclimate and overall soil fertility!
PropagationThe main method of propagation is grafting in order to yield more fruit.Vegatative cultivation has only been experimentally successful so far. Seed is great when fresh and properly germinated it can be directly planted into fields, however very slow growing.
CultivationGrows best in sunny dry climates, will tolerate light shade. Prefers well drained soil but can grow in nutritionally poor soils. The ideal temperature for growth is between 24-38? but this resilient tree will tolerate a range from 18-43?. Low elevation.Adapts well to mildly acidic, neutral, and basic soils. Vegetative cultivation is rarely successful, typically grafting is used for cultivation. Seeds are accessible and can be planted directly into fields but need to be fresh and properly germinated. Because Vitellaria paradoxa is such a slow growing tree grafting is the preferred method of cultivation.
PestsShea trees fall victim to parasitic plants such as African mistletoe as well as insects like stem borers. However the biggest threat to Vitellaria paradoxa is the increasing population and urban takeover of the trees natural environment. Although this is a well respected and relatively protected tree urban development plays a big role in its demise.Drought is also a factor of potential risk, shea trees thrive in the dry hot climate but do still need relatively consistent access to water.
HabitatVitellaria paradoxa thrives in the sunny dry climates of Sub-Saharan Africa.
Bark/Stem DescriptionTrunk has a large diameter of typically 30 cm however it is relatively short typically racing 3-4 m. The corky bark is a medium brown colour with distinct lenticels.
Flower/Leaf Bud DescriptionBeautiful tropical in appearance white flowers with approximately 8 outer petals and distinctive multiple stigma. Flowers typically grow in clusters.
Leaf DescriptionLeaves are oblong and green approximately 12-25 cm long and 4-7 cm wide.The leaves have a distinct wavy outline. Leaves grow in clusters at the end of branches.
Fruit DescriptionGreen smooth rounded fruits typically 4-8 cm long. Grows in clusters.Every fruit contains about 4 brown seeds each. The slow growing Vitellaria paradoxa does not fruit until the tree is 10-15 years old and typically will not yield a full harvest until 20-30 years old.
Colour DescriptionVitellaria paradoxa is a year round green tree with green fruits and white flowers. It does not have autumn colour because of its habitat.
Texture DescriptionMedium.
