We’ve grown this stunning perennial for years but there has always been some question to the exact species. All we know is that for foliage there really is nothing like it. Large spreading rosettes of pure metallic silver pinnate leaves are gorgeous all season. In summer and not very prolifically sporadic spikes of small yellow flowers rise above the foliage. Not the point of this plant and they can be removed if they are a distraction. To 1′ tall and forming a large patch in RICH, moisture retentive soil in full sun to light shade. Established plants can get by with much less water. Performance is equally as good in either position. Completely deciduous in winter. Beautiful leaves.
