Slipperwort
Calceolaria crenatiflora
Calceolaria crenatiflora is a showstopper of a houseplant, sporting pouched, slipper-shaped blooms in fiery shades of yellow, orange, and red, often dappled with contrasting spots. You grow it as a short-lived seasonal plant — enjoy the blooms for a month or so, then let it go without guilt, because it demands cool temperatures and precise care that makes long-term keeping more trouble than it's worth. Think of it as a spectacular floral guest rather than a permanent resident.

Fun Facts
The genus name Calceolaria comes from the Latin calceolus, meaning 'little shoe' or 'slipper' — an accurate description of those inflated, pouched blooms.
Pet safe
Non-toxic to cats, dogs, and humans. The fine leaf hairs can occasionally cause mild skin irritation in people with very sensitive skin.
