Eastern Redcedar (Juniperus virginiana)

These trees seem about 30 m tall, (I'm bad a judgung distances, but at least 3 stories) with scaly leaves and small blue berries. The previous home owner had the ivy growing on the tress scraped, so they're now draped with dead vines. Not exactly the most pictureque thing to have gracing the center of the house, but I haven't figured out how to remove it.

These trees were called cedars because the wood is aromatic and historically cedars have been prized for their aromatic wood. So now these are the trees that cedar chests are made out of, but no one calls them "juniper chests". These trees also seems to be used to make pencils and flavor gin (etymology blog etnry on gin and junipers).

This website and this one provide identifation tips, but mostly I just based this ID on the tree being so common. Native to the eastern US.

Mulberry bush (Morus Alba)

When I first figured out what this was. I had "Pop goes the weasel" stuck in my head. That was all I really knew about mulberry bushes. I was really excited about having a large tree that produced something edible. However, the 40 ft tree shadows my driveway, making a horrible purple mess several weeks a year. It's very invasive - there are at least 5 small trees, some of which I've dug up several times and they keep coming back.

White mulberries were first imported to feed silkworms, but silk is really difficult to make profitably.

Pecan (Carya illinoinensis )

Perhaps not as emblematic of the South as the magnolia,  these trees are still part of the local culture. Neighbors and strangers randomly drove up and picked bucket loads of nuts out of my yard (fall 2009), and the puppy hid the rest throughout the house in unlikely places. Now that I know the vaguely  creepy farmer's market on Eisenhower will shell the nuts, I'll actually try to do something with the next crop.

Easy to identify when the nuts are available. Pecans are a type of hickory tree, and technically not nuts but fruits (drupes, to be more specific). Mine give nuts every year, which seems to indicate one protandrous cultivar (produces pollen first) and one protogynous (is pollinated first). I'm not sure though, all the catkins seemed to appear at the same time.

Magnolia (Magnolia grandiflora)

 Smells beautiful when blooming. The sticky red seeds disturb me for reasons that I do not begin to understand. I always associated peaches with Georgia before I moved here, but I think I like having a magnolia better. Having a shady corner of the yard is great.

Id: Leaves simple ovate, smooth was fuzzy yellow underneath (pubescent). White flowers, pink fruit darkens, red seeds.
