Caracas Wigandia (Wigandia urens): The Stinging Giant with Velvet Leaves

Caracas Wigandia (Wigandia urens) is a striking, fast-growing shrub or small tree from the Andes, known for its enormous, velvety leaves and stinging hairs that deter herbivores—and unwary gardeners. Also called Wigandia caracasana, it's a bold foliage plant for tropical and subtropical gardens.

Dramatic Foliage & Flowers

Leaves can reach 2–3 feet long, broad, heart-shaped, and covered in soft, irritating trichomes that cause a painful, nettle-like sting. The effect is dramatic: a tropical, almost prehistoric presence. In spring to summer, tall, branching panicles bear masses of tubular, lavender-blue to violet flowers with white throats—highly attractive to bees and hummingbirds.

Culture & Caution
