i doubt they will come true from seed ....

i usually get plain old species 'looking' plants from my weirdo robur ... though most are not old enough to nut yet ... only the albomarginata.. which only gives green seedlings ....

but you never know.. until you plant them.. eh??? ..

wonder what robur crosses with;.. as far as the genetics go????

ken

ps: i have the general.. not cristata ... i googled IMAGES ... they look NOTHING alike.. so no.. you will not get a general looking .. from the cristata ...
