In 2000, Clarence (C.H.) Falstad, III of Michigan registered this tissue culture sport of H. 'Krossa Regal'. Like its parent, this cultivar forms a vase shaped clump with tall scapes of lavender flowers in August.

According to The Hostapedia by Mark Zilis (2009), "The contrast between the leaf center and margin of 'Regal Chameleon' is brightest in spring."
