1.2L Pot. Arisarum proboscideum is a cute little woodland plant with tuberous roots, from the Arum family. It is commonly known as mouse plant because of the resemblance of the flower to a mouse tail! It has arrow shaped leaves that emerge from the ground, creating a ground cover effect. The flowers are maroon and white with the long tail like tips. The flowers appear in spring but you may have to hunt them out as they can be hidden in the leaves. Partial shade. Goes dormant in summer.
