Sage, Salvia 'Allen Chickering'

 A dense and heavily fragrant shrub that grows to 5 feet tall with an equal or greater spread. Leaves are gray-green and approximately 1 inch long. The 2 foot long flower spikes of deep lavender flowers form on a tier of whorls in late spring and summer. Requires full sun, well-draining soil and only occasional summer watering and once established it requires even less watering. This Salvia is frost hardy to about 15° F. As with other native sages, to keep a dense and more attractive plant cut back in the winter by about a third or more when young - once mature with woody stems, only tip prune.
