COLOCASIA
esculenta. Southeast Asia. Taro or elephant ears. Taro is grown in Asia
and the South Pacific for its starchy tubers, treated much like potatoes. Here
it is cultivated as an ornamental. This is a giant tuberous perennial, related
to and somewhat resembling the calla lilies (Zantedeschia). It quickly
forms broad thickets with its wandering rhizomes. Each shoot consists of several
broadly arrow-shaped leaves up to 2 long on thick stalks up to 6
high. If it flowers, its light yellow, calla-like spathes are held beneath the
leaves. Our offering was received from Edward Hawkins, who grows a wonderful
variety of arum allies among other bits of vegetable insanity. It is either
the cultivar Fontanesia or something similar, with
nearly black stalks and undersurfaces on the purple-tinged leaves. The spathes
are bright yellow and seem to be freely produced in summer. It thrives in sun
or shade near the coast, part shade inland, needing rich, reasonably well drained
soil and regular watering. Hardy to around 20o,
resprouting from the tubers after devastation of the tops.
