A new planting of ‘Blue Heaven’® little bluestem shows one very different plant….it’s purple! Looks great, but will it last? Will it be as healthy and vigorous? We can all watch this one…it’s in the front gatehouse bed at the Arboretum on the right as you leave the grounds….where we can watch it without getting out of the car! Color mutations like this may or may not last through the growing season. Grasses appear to change quickly in variegation, cells that have more chlorophyll (green colored) being stronger, and more vigorous can crowd out weaker cells that have other pigments, or less chlorophyll, as this purple plant likely has.
