Hypoestes phyllostachya Care & Growth
Hypoestes phyllostachya can handle a variety of lighting conditions. It’ll do just fine in low light, but it may lose some of its vibrancy and variegation. It also tends to aggressively reach towards light sources, creating a potentially awkward growth pattern for a shrub. For best results place it in bright, indirect light.
Much like Nerve Plants, the Polka Dot Plant can be quite sensitive to watering. Preferring consistent, even moisture, it’ll often faint and collapse at the first sign of dryness. Thankfully it can be easily revived with a quick spritz.
Hypoestes will grow readily in most nutrient rich substrate options. A soil or mix with good water retention and drainage is best.
Temperature & Humidity
Although often grown as houseplants, Polka Dot Plants thrive in environments with lots of humidity and warmth. Making them ideal terrarium plants.
As a shrub, Hypoestes phyllostachya can quickly grow long and bushy. Regularly trimming the taller stems will help to maintain its size and shape, and promote a fuller foliage.
Polka Dot Plants can be readily propagated from cuttings at any time of the year. Simply take a suitably long cutting from the tip (e.g. 5 inches) then remove the leaves from the lower half so that it can be planted. As long as it’s watered, the cutting should readily root without much intervention. You can also harvest seeds from any flowers.
Varieties & Similar Plants
Within the Hypoestes phyllostachya species, there’s a huge number of varieties in just about every colour you can think of. They’re generally named for their foliage patterns; including ‘Dot’, ‘Confetti’ and ‘Splash’.
The only real difficulty in growing Polka Dot Plants is keeping their foliage in check. Regularly trimming or pinching off leggy stems will go a long way. It’s also worth noting that they don’t tend to live for all that long – often just a year or so after flowering.
