Gardeners' Notes:

Neutral Suze_ On Jan 20, 2006, Suze_ from (Zone 7b) wrote:

Colocasia 'Chicago Harlequin' was discovered by John Joicus of the Brookfield Zoo circa 1993, in a batch of normal Colocasia esculenta. The giant green leaves of C. 'Chicago Harlequin' are each blotched with large, lighter green, random sectors. The highlight, however, is the tall 5' stems, which are vividly striped with cream-and-green vertical bands. C. 'Chicago Harlequin' spreads rapidly in very wet areas by means of above-ground rhizomes.

Large enthusiastic above ground running Colocasia.

Leaves are randomly splotched with variegation. Stems are quite handsomely variegated.

I got this in the half price "Island of Lost Plants" area of a local garden center in January. It came out of dormancy OK and is holding its own against the spider mites; but, I keep losing leaves to stem rot.
