I've never really been into the perennial sunflowers (Jerusalem artichokes are a typical example), which I'd have previously dismissed completely as coarse and garish. Lately though I've come to appreciate them more and more, just for their sheer exuberance and sunniness.
The ashy sunflower is a case in point. The foliage is of good quality and complements the soft golden yellow flowers, which are produced over a long season in summer and autumn.
Any rich soil in sun.
