I saw this at a nursery today and was amazed by the leaf habit. It was labeled as a Crimson Queen, but it was unlike all the ones surrounding it. The leaves not only are bigger, but grow in more of a clumping pattern (like a Mikawa). It was also more greened out than the other Crimson Queens (and the other "red" laceleafs there like Tamukeyama, etc.). It's like a Mikawa, a laceleaf, and a linearilobum had a baby. Thoughts on what this cultivar could be? Very unique looking tree that I have to convince my wife to let me buy (already bought too many this year, lol).
My bet is that it is indeed a Crimson Queen, and the differences you're seeing can be explained by a variety of factors that that individual specimen is experiencing (sun exposure, watering, soil quality, stress, rootbound-ness, etc). And I would also therefore bet that if you bought this tree and a few of the others, planted them in the ground next to each other and gave them identical care, in a few seasons they would all look the same. But maybe it is something weird or mislabeled! I certainly have seen such things in the past.
My crimson queen has dark bark on both the trunk and branches..that one seems to have green bark…although hard to tell from the photos..I’ve also never seen my one with green leaves, always red even in a very shaded position. There are so many dissectums..looks a bit like my Ellen..See what colour it goes in the Autumn
Possibly Acer palmatum 'Dissectum Palmatifidum'. It has this thick dissected leaves 'almost non-dissected look' on the older leaves but much finer dissected leaves on the newer leaves.
