Polka dot plant (Hypoestes phyllostachya)

Polka dot plant

Features and Characteristics

Hypoestes phyllostachya, commonly called polka dot plant, is native to Madagascar. It is a herbaceous perennial or occasional subshrub that is noted for its ovate green leaves (to 2” long) which are spotted with rose, pink or lavender. As a bedding plant or houseplant it typically grows like an herbaceous perennial to 12-20” tall. Tiny lilac flowers are held on spikes up to 6” long and bloom sporadically in the summer.

Genus name comes from the Greek hypo meaning under and estia meaning a house for the calyxes being covered by bracts.

Care and Maintenance

Winter hardy to USDA Zones 10-1 In St. Louis, plants are grown as bedding annuals or in containers. Bedding plants are best grown in organically rich, medium moisture, well-drained soils in part shade. Pinch tips to promote bushiness. Some gardeners remove flower spikes because they are somewhat inconspicuous and tend to detract from the attractive foliage. Overwinter containers and grow houseplants in bright indoor light with some direct sun. Although bedding plants can be dug and potted up in fall for overwintering, it may be easier to simply purchase new plants each spring.
