YG seems to have the only consistently updated information. If you go to the comments section of each of the actual skills (Seedkin Eluder, for example), people have mentioned what types of mobs they seem to work against.

By the way, these only work on one enemy at a time, and have a pretty long cool down period. So if you find yourself cornered by two roselings, for example, you'll only be able to use Seedkin Eluder and become invisible to one of the two.
