These flowers come in various colors, including red, yellow, white, orange, and purple. Their blooms can be single, double, or even pompom-shaped. They can thrive in various climates, making them a popular gardener choice. The foliage of these flowers is dark green and deeply lobed, propagated through cuttings or division.
