About plant names...

California redwoods, native to portions of California and Oregon along the west coast of North America, are the only living species remaining of genus Sequoia. They live for a long time, up to 2,200 years.

Interested in the oldest trees? Check this Wired magazine article.

Identification: Redwoods reach 377' (115 m), the tallest trees on Earth, and may reach 26' (8 m) in diameter. Even the bark can be 12" (30 cm) thick. The bark is red-brown and deeply furrowed. The leaves (needles) are ¹/₃₂-1" (1-30 mm) long, and occur in different groups depending on their age. Older leaves tend to subdivide into smaller and smaller branches, while younger ones resemble hemlock, occurring in closely-spaced, flattened, opposing pairs. Cones are oval in shape, ½-1¼" (1.5-3.2 cm), with 15-25 spirally arranged scales. Tree size and the restricted natural location of these majestic trees serve to identify them.
