Silicon Tree

These silicon trees are an unnamed species of silicon-based life forms from an old planet close to the Milky Way's galactic center.

Biology
The silicon trees are native to an extremely old Earth-sized world orbiting a binary star system. Since all carbon is buried deep under a dense layer of siliceous materials, life on this planet developed using silicon-based compounds, which react with the atmospheric oxygen to create life.

As a result of their silicon-based biochemistry, these trees grow extremely slowly, to the point that a Human observer might fail to recognize them as living creatures. They're also so rigid that even hurricanes will not bend them. At most, the winds will tear off small fragments of the trees, which will subsequently grow into new trees.
