Alocasia California

If you want an instant tropical impact in your rainforest themed garden that survives hard freezes and is easily dug up overwintered as a bulb/corm further north where the ground freezes, the "California" elephant ear is the plant for you.  Its also called dwarf elephant ear, which to me is a misnomer.  Although "California" has 15 inch leaves while the full sized varieties of alocasias can have leaves up to 5 feet wide, the clumping nature of this plant makes up for the lack in leaf size.  The trunks on mine are over a foot tall now despite harsh winters, and it prolifically produces offsets or "pups" at the base which can be propagated or left in place for a full and rounded look.

This plant ships as a full size plant about 2 feet tall
