This very showy garden hybrid of two South African species (Crocosmia aurea × C. pottsii) is regularly cultivated and relatively hardy in southern Michigan. Collected in 2016 in Ottawa Co. by W. S. Martinus in rich soil along the Grand River at the drier upper boundary of a disturbed marsh, near the edge of the transition to upland forest.
This hybrid entity does not produce seed, but can apparently spread vegetatively by cormlets produced in the inflorescences and on the corms, and is considered invasive in some areas of warmer climates than Michigan (e.g., New Zealand).
