Depending on where you’re growing your polka dot plants, they can be both animal or perennial plants. They can be grown in USDA zones 3 to 10 indoors as perennials and outdoors as annuals. When produced outside, they tend to grow bigger, reaching up to 1 to 1.5 ft tall.
Breeders have developed many polka dot plant varieties that differ in the color of their leaves. Some have green mottled spotting, while others have dotted color hues. There are purple, scarlet, white, and lavender speckled leaves.
