  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Sep 8, 2023 10:50 AM concerning plant:
    This May of 2023 I bought a Cheyenne Sky Switchgrass at the local Home Depot in a white pot of Proven Winners, that is a large national company that supplies many garden centers with ornamental plants. This new cultivar has blades that are thin giving a fine texture and the blades are blue-green that develop a wine red color towards the ends of the leaves. This fall I will see if the whole plant turns red or not. However, it is still a young plant and might not do that at first. Furthermore, I noticed years ago that a similar older cultivar of 'Shenandoah' sometimes turned all red in fall and sometimes did not, depending on the weather. The older cultivar grows taller with slightly broader blades.
