Not to be confused with the alien fighters of a similar name, Agapanthus 'Back in Black' is a Lily-of-the-Nile from Holland's Piet Zonneveld. In late summer this 2005 introduction produces dark green flower scapes from the strap-like green foliage which age to black. The 2' tall flower scapes are topped with flower heads of very dark blue-purple flowers...quite striking and a favorite of hummingbirds. This is patented as an Agapanthus africanus selection but, being an open pollinated seedling, this species assignment is highly suspect. We have confirmed reports of Agapanthus 'Back in Black' surviving winter temperatures of -2 to -9F, without snow cover.
