Iris lacustris 'Captain Collingwood'

Dwarf Crested Iris, Lake Iris


Add to wishlist Remove from wishlist

The more rarely seen of the two eastern US dwarf iris species, lacustris hails from the great lakes region and is both darker in color and even more diminutive than I. cristata. Guess even cheese, beer, and hotdish can't live up to Southern cooking in terms of creating bulk in its denizens. Despite its Yankee origins this one has taken up with the enemy inheriting the name of noted British botanophile Collingwood 'Cherry' Ingram. Nothing remarkably different from the species other than perhaps a bit more white on the falls, what can we say the Anglo-saxon can't help but claim credit for what isn't theirs. Grows to just a couple inches high, dark purple flowers as big or bigger than the foliage
