This is by far the most commonly planted of the Japanese Maple types. It is a very common tree in the landscapes of the Mid-Atlantic. Probably about 1 out of 10 to 20 yards in the Philadelphia region has one planted in the front yard; it is way over-done and too obvious, taking away from the view of the house!. The general public likes it so much, they will find a seedling growing somewhere, plant it, and then wait about 20 years before it is finally an official tree of about 15 feet high. Slow growing (about 3/4 foot/year) and expensive to buy. When the weather turns hot, this variety loses some of its constantly reddish foliage color to become reddish-green, then it turns really bright red in the autumn. The 'Bloodgood' cultivar holds the color better in summer.

When we moved to this Petersburg, Virginia, Zone 7-A house and yard in 1996, there were two mature acer palmatum atropurpureums on either side of the house in the front yard. They were graceful and colorful, the bright red of early spring darkening and then becoming more of a purplish bronze in the heat of deep summer. One of them died in 2005; an extension agent (who was given soil and plant samples) said that it was probably because it was nearing the end of its lifespan of about sixty to seventy years. The surviving tree must be twenty-five feet tall, and although it looks healthy, I don't know how much longer it has to live. The two maples have put out hundreds (thousands?) of seedlings, apparently something which happens then they near the end. They will come up in flowerbeds, i... read more
