Does anyone grow this one? Can you tell me more about it or show pictures? How do the leaf size and color compare to a palmatum?
Re: Acer J. 'Ogurayama' Nice habit, small obicular leaves, medium green, fairly heavy pubescence (sieboldianum?). Mine is in a container and about 7 years old, very well branched, upright, 5' high, flowers and seeds heavily. I like it. Fall colors, so far, have not been outstanding, but in a container this is not unusual, I think. They are supposed to be great.
Re: Acer J. 'Ogurayama' Vertree considered this cultivar like one of his favorite japanese maple. Most references (included Vertree) place it as a shirasawanum cultivar but Van Gelderen considers it as a sieboldianum. Here are some links : http://www.worldplants.com/ogura.htm http://www.whitmanfarms.com/tree_pages/acersiebogurayama.htm
Re: Acer J. 'Ogurayama' Hi PoorOwner-- You have been moving fast in maples to be asking about this plant--I suspect you will not find a clear answer at this time but here is what I have to offer. Last year I bought the smaller-leaved more yellow colored tree as A.s. 'Ogurayama'. Realizing it was not a shirasawanum I started to research and found much more evidence for a tree labled as Ogurayama to be a japonicum. What has happened is that the tree looks much like a sieboldianum and maybe what some Europeans are calling sieboldianum 'Ogura yama'. Wanting to know more, I found the larger tree with more orbicircular leaves and darker green color this year being sold as A.j. 'Ogurayama'--Fullmoon maple. Well, with some research, it is also not likely the tree that has been traditionally sold as that plant and again exhibits some sieboldianum-like characteristics. What I will tell you is both are outstanding trees, the first turning a nice pumpkin in the fall and having the yellow tones all season so far. The second tree is a beauty being very complact, with an 1" calliper on the trunk, and only about a foot wide. I have not seen fall color on it. If at any point you can find a lesser known or more rare japonicum or sieboldianum I would recommend that yo buy it. While it may be hard to identify, they make outstanding trees. At some point, when I have a better idea of what is going on, I hope to move some photos into the gallery, but they can stay here for now. Jacquot makes a good description and as Andre hints, I think it is pretty safe to move what we are seeing sold now out of shirasawanum as Vertrees discusses. What we are seeing now may not be anything like what was being traded during the writings of the text. Think about mixing up all the similar looking japonicums and sieboldianums and then trying to sort them back out after they have been bastardized a bit. No easy task. Michael
this is a great little "boring" tree with wonderful fall color and redish color bark in winter the label on my tree has it as a shirasawanum.
