Acer palmatum ‘Emperor 1’ is a good choice for areas that get occasional late frosts.  Buds break about two weeks later into spring than most Japanese Maples, so they are protected just a little bit longer.  Make sure to plant where they will be protected from scorching sun or hot dry winds, and you will be rewarded with brilliant red new growth which matures into leaves that hold their deep claret hue long into summer, and flare up brightly again for the autumn display.  Upright and fountain shaped, this tree makes a big visual impact in any garden.
