What is the longest blooming indoor flower?
Rarely without their showy blooms, anthuriums are known as the world’s longest blooming houseplant. Each bloom can last up to eight weeks, and new ones will pop up often. These aren’t actual flowers, but modified waxy leaves. Anthuriums flourish and bloom best in bright indirect light. While many perennial flowers have long bloom times, the threadleaf coreopsis moonbeam variety (coreopsis verticillata ‘moonbeam’) is a perennial with the longest bloom time. Moonbeam blooms early in the summer and will continue to do so until the end of the fall.
