Like most quintessential Southern plants, their history is fanciful and somewhat eccentric. Plants in this genus were originally called Marica, in honor of a mythological water nymph. The common name, apostle plant, reflects the belief of some gardeners that the plants will not bloom until they have acquired 12 leaves. Walking Irises grow from clumping, rhizomatous rootstocks. Gardeners in colder areas will find that several species make interesting and durable houseplants.
All species produce ephemeral, yet showy, iris-like flowers at the end of arching stems.
It is imperative not to deadhead the spent blossoms as this is where new plants will sprout. Neomarica caerulea, my favorite, is indigenous to the rainforests of Brazil. This species prefers acidic soil when grown outdoors. Fertilize monthly with Miracid during the growing season. In Florida, Neomaricas should be sited in part-shade.
