Present on Pacific Islands?  yes

Primarily a threat at high elevations?  no

Risk assessment results:  Evaluate; score: 1 (Hawaii-Pacific Weed Risk Assessment for Schotia latifolia)

Common name(s): [more details]

English: bush boer-bean, forest boer-bean

Habit:  tree

Description:  "Schotia latifolia is a tree which grows up to 3 m high where the habitat is dry and scrubby, but may reach 15 m when growing in more moist areas. The crown is rounded in shape unless growing in a forest habitat where the tree will be taller and more slender, the crown shaped according to the forest canopy. In Mpumalanga it is usually found on mountain slopes. The bark is usually smooth and reddish brown to grey. ¶The leaves are compound, dark green and have a rather leathery texture. The leaflets are elliptic and asymmetrical; the 3-5 pairs of leaflets are arranged opposite one another although the actual leaf arrangement is alternate. The pale pink flowers are borne in clusters on the ends of stems. Flower colour can be variable, from flesh-coloured to white-ish. Unlike S. brachypetala, the petals are well formed and not very narrow or reduced to thin filaments. The flowers appear in October and November. When not in flower it may be confused with S. brachypetala but this tree usually has more leaflets (4-7 pairs) per leaf. ¶The pods are broad, flat, brown and woody when mature. As with the other boer-bean species, the pods peel away from their outer edges, leaving the narrow rims with the seeds attached hanging on the tree. The seeds are light brown with a yellow attachment called an aril." (SANBI/Plantz Africa)

Habitat/ecology:  "Schotia latifolia grows in forests and forest margins, scrub and bushveld. The main centre of distribution is in the Eastern Cape [PIER ed.: of South Africa] but it does occur in restricted areas within Mpumalanga and Limpopo Province. Since it occurs in a variety of habitats, it would very likely tolerate garden conditions, although it does not occur in very frosty areas. The tree will need to be well watered if it is to attain a tall and graceful stature." (SANBI/Plantz Africa)

In cultivation(?): "Partial Shade, Sun" (Kumbula Indigenous Nursery 2016 as cited by HPWRA)

"Soil type: Loam", "PH: Neutral" (South African National Biodiversity Institute 2007 as cited by HPWRA)

Propagation:  For cultivation: "Propagate Schotia latifolia from seed in spring. Pour hot water over the seeds and leave them to soak overnight. They should quickly swell as they absorb the water. When the seed coat becomes wrinkled they are ready to be sown." (SANBI/Plantz Africa)

"propagated from seeds" (Kunkel 1978 as cited by HPWRA)

Native range:  Schotia latifolia Jacq. (Fabaceae) is native to South Africa. (GRIN)
