Alocasias are not difficult to find, and they are worth looking for if you want a spectacular specimen plant. The erect, thick stems of Alocasia sanderiana carry arrow-shaped leaves 12-16in/30-40cm long and 6in/15cm wide.
They are metallic silver-green, broken by yellowish gray veining, with scalloped edges and a thin white margin; the undersides have a purplish tinge. The rather insignificant petalless flowers are held on a spadix within a typical arumlike spathe.
This attention-grabbing plant is, unfortunately, not really happy in normal room conditions and should be returned to a greenhouse to recuperate after a few months. 
A rest period is essential in winter, during which the soil should be allowed to become almost dry between waterings, and feeding can cease completely.
