Did you know that gloxinia can be grown as house plants? True! Gloxinia are fabulous gift plants AND can be spectacular house plants if you give them proper care. A few years ago, a gloxinia flowering houseplant (Sinningia speciosa) was considered a perennial. The plants would bloom and then die back. After a period of dormancy, the plant would regrow, delighting its owner with a fresh flush of big, velvety flowers.
