Picea mariorika 'Kobol'

The grex is Picea mariana x Picea omorika; Kobol is a dense globular form with fine grayish blue needles a 1972 Jeddeloh cross between Picea mariana ‘Doumetii’ and an unknown omorika clone. I’m surprised that no one is making large numbers of controlled dwarf conifer crosses the market for such things would seem to be huge and the transfer of pollen very easy.
