An Amaryllis, the flower we commonly see in November and December, will continue to come back every year over several years if it is cared for. It's a perennial, as are most of its family members (family Amaryllidaceae). Note that almost all of these popular flowers, though they are of the family Amaryllidaceae, are actually of the genus Hippeastrum (which numbers some 80 species). The (only) flower of the family Amaryllidaceae that is of the genus Amaryllis is Amaryllis belladonna, which is similar to Hippeastrum. Links are provided for the curious.
Florist chrysanthemums are annuals. Chrysanthemums grown in the garden can be perennials if they are planted long enough to get their roots established before a hard freeze.
Petunias are annuals.
