Frost-tender, it works well in a conservatory, greenhouse, or sunny windowsill.

Resume feeding and regular watering when the plant begins to grow again.

This compact shamrock hails from Brazil. Instead of the bright green color of what we think of as an Irish shamrock, this more geometric variety has a deep purple color with velvety leaves. This tender plant displays tubular, five-petaled light pink flowers. It is a heavy bloomer. This intriguing plant opens and closes in response to light. Both the flowers and the leaves respond.
