kol-oh-KAY-shah ess-kew-LEN-tah
Genus:
Colocasia
Kitchen garden rhubarb doesn't hold a candle to 'Rhubarb' elephant's ear, at least not in an ornamental sense.
Noteworthy Characteristics:
‘Rhubarb’
earned its name for the slender red stems that support its spade-shaped foliage.
Care:
Give
‘Rhubarb’ full sun or partial shade and rich, moist soil, and it will return
the favor by producing lots of pretty leaves on exciting red stems. This
elephant’s ear can even live happily submerged in water. Gardeners in cool
hardiness zones may overwinter plant’s tubers indoors covered by peat moss
during winter, after the leaves have been desiccated by frost.
Propagation:
Plant
‘Rhubarb’ tubers when soil is consistently around 70̊F. Separate offsets in
spring or summer.
Problems:
If
the tubers are kept too wet during winter storage, they may rot. Keep the
tubers and peat moss slightly damp, never wet.
