amazingly , even though they may become slightly leggy and flower with less abandon , many Sunday - tolerant plants perform well in the tad — and do so using less H2O . For example , several rosaceous miscellany will suffer varying degree of shade and still bloom , and will call for far less water than if they were sited in full sun .
Plants shaded from the hot good afternoon Sunday are keep cooler , which play down transpiration rates and in turn allows the plants themselves to retain more moisture .
