I used to think that the various twigs I see on redwood forest floors came from different species of trees. Then I learned that S. sempervirens will just grow different types of needles when they get big enough to have to deal with multiple climates at once. The needles start off flat and long near the ground and get shorter, thicker, and scalier as it gets warmer and drier higher up.
So these are all from coast redwoods, just from different heights in the trees.

- Leaf sprays from coast redwood trees arranged according to where on a tree they are from. The rightmost twigs have long flat needles arranged like chains of feathers, and the leftmost twig is covered in spirals of short, scale-like needles. The two in the middle are intermediates between the two extremes. (remote)
