• TB 'Dusky Challenger' was blooming at the Minnesota Landscape Arboretum, zone 4b, approximately June 1-16, in 2017. Even though I didn't see any Purple Based Foliage at the base of the leaves, Dusky Challenger does have some very faint purple coloring on its spathes. It shows up better when the buds are newly formed. -- HollyJohnson2017 -04-01 - 17 Aug 2017
