Tarua

Many years ago,  I visited a Polynesian market in New Zealand and bought some tubers that were called Tarua in the South Pacific Islands…similar but different (and larger) to the more common Taro (Colocasia esculenta). For a plant that supposedly originated from tropical lowland Malaysia, Taro is a surprisingly cold hardy plant making a nice edimental house plant that can be outside in the summer even in my cool climate! I took a Tarua tuber home and grew it as a house plant for some years. It is probably Xanthosoma sagittifolium, also known as Elephant Ears, and closely related to Taro and similarly quite hardy! See the pictures below.
