On release, Elder Trees were absolutely ancient trees, not just a naming convention. Elder seeds were just one of the skill overreaches pinned onto the release of Prifddinas (and a lot of us decried it at the time - though I guess we just don't care anymore).
I choose to interpret it as a gameplay mechanic, rather than a canon thing. Elder seeds are the gameplay function that I use to gain access to the lorefully pre-existing Elder trees.
