Aesculus x bushii
Common name: Bush's chestnut, buckeye
Aesculus x bushii is a natural hybrid of Ohio buckeye (Aesculus glabra) and red buckeye (Aesculus pavia) that occurs in the wild. The hybrid off-spring are quite variable and have showy multi-coloured flowers in spring. It is deciduous with opposite compound palmate leaves. As the buds enlarge during winter and the bud scales fall away, new spring leaves unfurl from the well-wrapped bud package, a seasonal pleasure of the buckeyes and horsechestnuts. The profuse lumpy, hard fruits this tree produces in late summer are toxic due to saponins.
