About
Hypoestes phyllostachya, the polka dot plant, is a species of flowering plant in the family Acanthaceae, native to South Africa, Madagascar, and south east Asia. The spots often merge into larger areas of colour.
The genus name Hypoestes comes from the Greek hypo, meaning "under", and estia meaning "a house"; this refers to the calyxes being covered by bracts. The Latin specific epithet phyllostachya means "with a leaf spike".
How to grow it
Hypoestes phyllostachya is cultivated as an ornamental plant and is familiar as a houseplant, but can also be grown outside as an annual plant in cooler climates or a perennial in the subtropics and tropics. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit. Many different cultivars have been created with different foliage colors.
This plant does best in partial sun. In the United States, it is winter hardy in zones 10 and 11. It has low drought tolerance, but is rarely damaged by deer. It spreads by cuttings and seedlings.
