Hypoestes phyllostachya · Freckle face, Flamingo plant

Polka dot plant (Hypoestes phyllostachya) — a compact, bushy foliage houseplant, about 30 cm tall, with thin oval leaves heavily spotted with pink, red or white; the small lilac flowers are not its attraction. Polka dot plant needs partial shade. Water it about every 5 days while it grows and about every 10 days in the winter rest.

Watering and repotting polka dot plant through the year

It lives indoors all year, so it has no sowing or planting dates: it grows from March to September and rests from October to February (the other way round in the southern hemisphere).

Repot it about every 24 months.

When to plant polka dot plant?

Plant or repot polka dot plant in spring, as it starts into growth; early to midsummer also works. It is a houseplant, so it has no outdoor planting date and no frost decides it: just avoid autumn and winter, when growth slows and fresh compost stays wet too long. After that, move it to a slightly larger pot about every two years, or sooner once roots circle the pot or grow through the drainage holes.

Growing notes

Light

Bright, filtered light gives the best leaf colour. Strong summer sun scorches and fades the leaves, while deep shade turns them greener and the plant leggy.

Soil

Porous, organic-rich potting mix, either loam-based or peat-free.

Care

It likes warmth, 18–27 °C, and humid air, from misting, a tray of damp pebbles or a steamy bathroom; dry air from a radiator browns the leaves. Let the top of the compost dry out before watering, since it is prone to root rot. Pinch back straggly shoots and remove the small summer flowers to keep it neat. From April to September feed with a liquid houseplant fertiliser every two or three weeks, at the label rate, because overfeeding gives tall, spindly shoots. Repot every two or three years. Cuttings root easily in water. Powdery mildew is likely in dry air. Non-toxic to cats and dogs.
