I am a Japanese Gardener and we often apply this method to the Gingko (as a result the height of the tree grows faster). If you plant your tree where people will walk then you do not want branches lower than head level. Cut all your side branches off when they appear this will rapidly increase height. When the tree reaches head height you can let the side branches grow. This method you can have a 6 foot tree in 3 years. Also tree in pot will never grow quickly and therefore Gingko can be used as bonsai.

Great site for photos of some mature plants. The 2nd photo looks like a Cobra on the left and the standard on the right is amazing. I can't believe it is such a tall standard.

That's the problem here, the name Abies x koreocarpa was never validy published. Please let me know if it is. On the other hand I like the following names very much: -Abies x koreocarpa (A. koreana x A. lasiocarpa) -Abies x lasiokor (A. lasiocarpa x A. koreana) -Abies x procekor The first specie name shows the motherplant were the cones came from, which is in my opinion very important to know. I use these names at my website if I have these availlable. This year I have availlable Abies x koreocarpa 'Fürstenburg'. I also have the following Abies crosses listed: Abies koreana x Abies pinsapo 'Zipfelmütze'. There's never a name published for this cross. Should it be named Abies x koreapo 'Zipfelmütze? Abies grandis x 'Leuteneggeri' This one is also from Germany but this name doesn't show us that the cross is between an Abies grandis and an Abies concolor. A better name should be Abies grancolor 'Leuteneggeri' Btw this is a very nice cultivar, it looks like a blue Abies grandis! The name Abies x vilmorinii doesn't show us that this is a cross between Abies pinsapo and Abies cephalonica. Maybe Abies x pinsonica was better... Final conclusion: The original name for the 'Waldgrenze''(which means 'Forest Border') is Abies koreana x 'Waldgrenze'. A better name should be Abies x koreocarpa 'Waldgrenze' Maybe there must be new nomenclature rules to make it clear which the parents of these crosses are. Till now both the parents names can't be found in a lot of crosses.

I think we have to stay with 'Tubifolia'. This is because most of the cultivars of this species were found after 1959 and got a Latin cultivar name, like 'Globus', 'Pendula' and 'Pragensis'. As time passes, people were used to these names and it is not very smart to rename them into a modern version because this will causes new confusions in plant naming. By using 'Tubeleaf' it won't take long before the following quiestion will be asked here at this forum: Hi, I bought a Ginkgo biloba 'Tubeleaf', but I can't find any info about it at the internet. Is this the same one as 'Tubifolia'? We must try to avoid this kind of situations, because there are plenty simular one's already...
