A tender perennial hybrid plant (Pelargonium x domesticum) favored in horticulture for its upright growth and spectacular, ruffled blooms. Unlike common zonal geraniums, regals require cool night temperatures to initiate flowering and are typically grown as greenhouse or conservatory specimens. They are highly sensitive to overwatering and require well-drained growing media.
