    I’d guess that has a lot to do with generation time – much the same can be said of cultivars of most other trees. When there’s a 10-30 year generation gap between first and second generation hybrids, not much gets done.

    Conifers are wind-pollinated. To cross them you’d have to do something like cut a branch of one and shake it next to another, that had been kept enclosed in a bag to prevent uncontrolled pollination. I think this is the kind of thing that is done to select for timber production, but apparently not so much in ornamental hort.

    Welch & Haddow (1993) attribute name ‘Frosty’ to Welch, via Swartley’s 1984 hemlock book. W & H also say it’s a bush. Gelderen & Hoey Smith (1996) call it a “medium-sized tree”, say it’s a “good grower.”
