(aka: Alstroemeria 'Inca Ice') Alstroemeria 'Koice', from Holland's Könst Alstroemeria, has been a star in our trials as well as at Walters Gardens in Michigan. For us, the clumping Alstroemeria 'Koice' begins flowering in early June and continues nonstop until frost. The 18" tall stalks of Inca Ice princess lily are topped with clusters of light peach flowers highlighted with cinnamon flecks...a hummingbird treat. In 2011, Alstroemeria 'Koice' sailed through -12 degrees F in western Michigan!
