There are lots of trees in the "Live Oak" category, they don't drop leaves all at once but do generally shed a lot in the late winter though there are already replacements there, so the tree is never bare. Scroll down for a list of varieties called "live oak."

I just took a wonderful and rather deep plunge through Wikipedia and various links to see where some of the classifications have ended up. When I took botany and forestry classes in the 1970s the oaks were still considered a sub group of Elms, but no more. And other changes have occurred, with research and RNA or other genetic readings, I'm sure.

Metasequoia isn't exactly like the sequoia, as Steve pointed out, they are deciduous. I had poor luck getting one established in the front yard (I know know what happened, it was rootbound and I didn't get it to ever establish because of that - now I plant trees much differently and almost always successfully). I have a couple of baldcypress in the yard, also deciduous.

Bristlecone pine are trees with a story - the US Forest Service, years ago, found one they thought was the oldest and some idiot cut it down to count the rings. Since then they've found an older one and it's hands off! There are other very old plants in the world, I think the creosote bush (Larrea tridentata, found from the American Southwest down through Central and into South America) grows in such a way that there is a ring of plants, all genetically the same plant. See King Clone for more information about them. (They smell wonderful when the air is moist or after a rain).

I would love to know more about how the Wollemi pine was discovered so recently. I took a detour down that Araucariaceae taxonomic line and see that the Norfolk Island Pine is a relative. And another branch leads into the "monkey puzzle" trees that came from South America (they grow well in the Seattle area so I saw many as a kid - they're a tree you would never mess with more than once!)
