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, in clay-soil, in mulch, in the lawn. I don't consider this entirely a problem because it won't last forever and because they do make beautiful trees. It is a bit overwhelming, however.
