Gerard Heemskerk 2012. First Frost sport. A medium-sized hosta with thick blue leaves with a wide, yellow-green border that quickly turns white. 16″-18″ tall scapes, pale lavender flowers.  Originator’s photo as it appears on the Hosta Library. To Gail and me, Hosta Firn Line is so close to Blue Ivory in appearance that we have decided not to carry it anymore. We will continue to offer Blue Ivory. We’ll leave this description online for another couple years so those interested in Firm Line will have an opinion. Give us a call if you have questions.
