Water is one of the most limiting factors for many mountain homeowners with wells.
Several perennials require less water and grow well in Gardens above 8,000 feet in elevation. Pair them with the compact varieties of lavender-blooming catnip. Taller water-wise perennials include oriental poppy and yellow yarrow. Mauve-flowered beebalm grows on dry hillsides and does well when planted among other tall flowers to conceal the spindly stems. Consider support from baby's breath and tall native daisies.
