Differs widely in appearance from its more common relative, Portea petropolitana v. petropolitana. Growing in a spreading , open rosette of densely lepidote, silvery leaves that are pointed and bear black spines on the margins. The inflorescence is a panicle of loose branches and bracts of lavender, very attractive. Grows to over 30 inches tall and wide.
If you go back far enough, you may remember Portea ‘Pink Shadow’. This is (or was) that plant. It sold under that name for a few years until it’s true identity was found out, but that was years ago.
