Safety Overview
1.Wahoo — Introduction & Highlights
Wahoo, scientifically known as Euonymus atropurpureus, is a captivating deciduous shrub or small tree native to the eastern and central regions of North America. It typically reaches heights of up to 8 meters, featuring a slender trunk with a diameter of about 10 cm. The bark is characteristically gray, smooth, and may develop light fissures with age.
Its twigs are slender and dark purple, sometimes exhibiting four-angled or slightly winged structures. The leaves are elliptical, measuring 8-11 cm long and 3-5 cm broad, with a distinctive long-pointed tip and finely serrated margins. In late spring to early summer, Wahoo produces inconspicuous bisexual flowers, approximately 10-12 mm in diameter, adorned with four brown-purple petals, four green sepals, and four stamens.
The most striking feature of the plant is its smooth, red to pink, four-lobulated fruit, which splits open in the fall to reveal bright orange seeds, giving rise to common names like 'Burning Bush' or 'Bursting Heart'. Wahoo thrives in well-drained, moist soils, often found along stream banks, in open meadows, and on wooded slopes. It reproduces effectively by reseeding, attracting various birds and wildlife with its vibrant berries, which are, however, highly toxic.
