Story About Mutated Vegetation on Shipwrecked Island

Do you know this story? guy goes on island that ship filled with chemicals crashed into. chemicals leach into island. over time cause island vegetation to mutate.

Mutated vegetation's life cycle no longer reproduction-based. hence life of the individual becomes life of species. plants grow HUGE. This was a really cool story, I'd like to read it again. I don't know who wrote it or what issue of Omni it was in, do you?
