Schotia brachypetala

Botanical name

Schotia brachypetala

Other names

Weeping boer-bean; African walnut; parrot tree; huilboerboon (Afrikaans)

Family

Caesalpinioideae

Dimensions

A large, spreading, leguminous tree with a round crown, up to 16 m in height

Description of stem

Brown or grey and rough; a single stem tree, branching may commence low down

Description of leaves

Imparipinnate with 4 to 6 pairs of opposite leaflets; oblong, characteristically asymmetric with entire margins, sometimes hairy and wavy; young leaves lighter green and shiny, sometimes reddish for a short period, making the spring appearance very attractive; mature leaves are dark and glossy

Description of flowers

Dense panicles of maroon flowers appear on the old wood, with the short petals often falling early (brachypetala = short petals), leaving the conspicuous filaments on show; the dripping nectar produced in profuse quantities in spring, before the normal summer rainy season, causes the 'weeping' alluded to in the common name; the flowering time varies between regions and even between individual trees; a five year old tree will normally flower; attracts a variety of birds (including parrots) and insects

Desciption of seed/fruit

Flat and hard pod of up to 10 cm in length, containing light-brown flat, hard seeds attached to a conspicuous yellow aril

Description of roots

 

Variation

Flower colour and flowering season variations

Propagation and cultivation

Grown from seed or truncheons; seed germinates very easily; the tree is slow growing in colder, drier climates and may remain smaller, faster in warmer, high rainfall parts of its distribution range

Tolerances

Does not thrive in too dry climates

Uses

Planted in bigger gardens, parks and along streets as an ornamental tree; a bark decoction has been used for the treatment of heartburn and hangovers, also for dysentry and diarrhoea; the mature seeds are sometimes roasted and eaten; the leaves are browsed by game

Ecological rarity

Common, not threatened

Pests and diseases

 

Other

As elephants are said to become intoxicated from marula fermenting in the sun, there is a report (with picture) from Sydney's Botanical Garden in Australia of a rainbow lorikeet indulging in S. brachypetala nectar in the sun, apparently capable of becoming intoxicated if the fermentation of the sugary liquid proceeds far enough according to the local Garden Curator (www.smh.com.au)!
