For many years the Holy Grail of the Japanese maple growers has been a red dissectum (laceleaf) cultivar that has an upright habit instead of a weeping/mounding form. 'Lionheart' is the most recent contender, but it still has a somewhat weeping habit. I think it's arguable that an upright laceleaf has been around for a long time, and it's 'Burgundy Lace'. It's true that the leaves are a bit wider than most dissectums, but I have been known to mistake it for one more than once. In any case, this is one of my favorite cultivars even though it "greens up" in midsummer unless sited so it is protected from the hottest sun but not too heavily shaded. The spring and early summer color is a deep, rich, glowing burgundy, followed by a good red in fall. Though nearly as wide as tall, it manages an airy, graceful appearance, and stays relatively small, perhaps 8' in 10 years, maybe creeping slowly to 12' at maturity. Though it is an American selection, 'Burgundy Lace' received Britain's Royal Horticultural Society Award of Garden Merit in 1993.
