Water rational use for garden irrigation is a constant concern in view of it waste, because researches have shown that it corresponds to 40 to 70% of the domestic consumption. One of the strategies employed to avoid this waste is the selection and planting of drought stress resistant plants. This research aimed to evaluate the Stenachaenium megapotamicum growth, a sub shrub plant, with ornamental potential, native from South Brazil, grown under different water regimes. Two experiments were developed: a) during the spring by applying three irrigation frequencies: daily, every other day, and every three days, b) during the fall / winter by applying four irrigation frequencies: daily, five, seven and nine days. Results obtained showed that S. megapotamicum is an adequate annual plant summer for landscape projects focusing in the efficient water use.
