Hosta 'Firn Line'

This sport of H. 'First Frost' is a small size (10 inches high by 16 inches wide) cultivar that was registered by Gerardus Heemskerk of Heemskerk Vaste Planten in the Netherlands in 2012.  It has blue-green foliage with creamy white marginal variegation. The leaves are lightly cupped, elliptic and have thick substance with a slightly shiny top. Medium lavender, bell-shaped flowers bloom from July into August.


According to an online dictionary, the word firn means "granular snow, especially on the upper part of a glacier, where it has not yet been compressed into ice."

An article by Warren I. Pollock in The Hosta Journal (2014 Vol. 45 No. 1) states that, "H. 'Firn Line' is the Correct Name, not 'Firm....The term is from the Swiss German firn meaning 'last years'...and has to do with the line on a glacier between the white snow on a glacier."


An article by Warren I. Pollack in The Hosta Journal  (2020 Vol. 51 No. 1) titled Doppelgänger Hostas: Fancy Name for Look-alike Hostas, included a long list of hostas which various hostaphiles, published articles or other sources have indicated "look" the same. Some of these are, in fact, the same plant with two or more different names. Others are hostas that vary in some minor trait which is not immediately discernable to the casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the plants listed but then, their opinions are based on visual observations and interpretations.

H. 'Blue Ivory', H. 'Firn Line' and H. 'Great Escape'.

"H. ‘Firm Line’ (2012) – Due to a typographical error on the part of the registrar this was incorrectly registered as H. ‘Firm Line’ and should have been H. ‘Firn Line’. Further, as it was published, albeit incorrectly, and attached to a description, the registrar formally announces that the incorrect name is also removed from possible future use."
