Polka dot plants are not especially difficult to grow, they have a moderate growth rate, and they remain relatively small once they're mature, especially when grown indoors. They can be grown in containers, both indoors and outdoors. Warm temperatures and humidity are key to growing polka dot plants. Expect to water regularly unless you get sufficient rainfall. They also need regular feeding throughout the growing season (spring to fall). Moreover, polka dot plants bloom sporadically, typically during the summer, with insignificant lilac flowers on spikes. You can pinch off these flower spikes to keep the plant’s energy focused on growing its vibrant foliage. Grow polka dot plant in a bright or medium-light spot. It can tolerate bright spots indoors and doesn't mind a little direct sun on its foliage.
