Bowkeria citrina is an erect, evergreen, multi-stemmed shrub with leaves that smell strongly of lemon when crushed. The flowers borne in summer are bright yellow and make a wonderful display followed by the fruits that look like polished cardboard which remain on the tree even after releasing the dust-like seed.
It is tolerant of frost, requires full sun and moderate amounts of water but the display of yellow flowers and lemony scent makes it a wonderful feature in any garden. It is however slow growing.
Bowkeria citrina prefers a cooler climate but will do well in Johannesburg.
