About
Cortaderia selloana 'Rendatleri' is a robust, clump-forming perennial grass that reaches heights of up to 3 meters and can spread more than 1.5 meters in width. It features evergreen, arching leaves that are blue-green and have a serrated edge. In late summer to early autumn, this variety produces distinctive plume-like panicles with drooping, one-sided clusters of glistening purplish-pink spikelets.
