Hosta Firn Line will form a small to medium mound of 18"-22" in height, with a spread of up to 30", at maturity. This absolutely beautiful Hosta, has thick, heart-shaped, intense blue leaves with a wide, creamy margin that matures to pure white. Sport of 'First Frost' that is very similar to Hosta Blue Ivory and Hosta Great Escape. The contrast of the leaves really grabs your eye from a distance. Pale lavender flowers appear early summer on 24" long scapes. Slug Resistant Hosta. Takes a little while to get to its best but this is probably one of the most stunning Hostas in my collection, when it gets to maturity. Dappled shade for this one.
