Russian Sage
"Here, some pinks & laurel leaves,
& a handful of sage."

The usual variety of Russian Sage offered in nurseries is called 'Blue Spires' & is a Hybrid of Perovskia atriplicifolia and P. abrotanoides, though sold as P. atriplicifolia. Plus there is a recent smaller version called 'Little Spire,' likewise hybridized. But the two clumps shown here (photographed on the alley-side August 2003 & July 2004 respectively) were not labeled 'Blue Spires' or any other cultivar name, so presumedly are the species, though I'm uncertain. The primary difference is the wild form gets taller & perhaps lankier than the hybrid Russian Sage cultivars.
The species grows to five feet typicalyl, but not impossibly over six feet. The many tiny flowers on slender spikes look like smoky-blue branches from July to first frost, when flowers are replaced by attractive fall colors of gold & yellow, then whitish grey twigs in winter.
The woody stemmed bush has two kinds of silver-green leaves, the lower leaves deeply & finely cut, the upper leaves simpler & serated. To call it low-maintenance is an understatement. It wants full bright sun & not much water, even normal rainfall may be too much for it, so it is good to put it on a dry ledge or mound to insure maximum drainage.
The leaves have a marvelous sage-minty odor especially when brushed against. Long-lasting as cut flowers, they can bring quite a pleasing scent into the home. They also hold their scent as dried flowers.
Hardy at minus 20 to minus 10 degrees, at the colder end of its tolerances it will die to the ground & return in spring, but is otherwise a deciduous subshrub, dormant in winter when the grey twigs still hold interest. If it experiences too much shade or too rich a soil, it may need staking, but in full sun is quite woody & stands upright without assistance.
In spring before new growth begins, it is ideally cut back to a foot & a half or two feet height to assist attractive new growth, but at the very least any branches damaged or dead through winter should be trimmed off.
Though it can be divided autumn or spring, it spreads so slowly that divisision is a slow method of propogation. It can easily be started from four-inch stem cuttings.
Russian Sage is native of Afghanistan & western Pakistan rather than Russia, but the genus is named for a Russian general. In 1995 it was selected as Perennial of the Year by the leading association of perennial growers.
