About

Arisarum proboscideum is a rhizomatous perennial that forms dense clusters of arrow-shaped, glossy green foliage, reaching lengths of up to 15 cm. In spring, it produces flowers characterized by a dark purple-brown spathe that tapers into a long, slender projection resembling a mouse's tail, with a white base.
