Sure, it sounds lame But its not lame if it works.
Like the flower knight of the ebon hill. His armor looks absurd and he guards his territory by growing flowers on command and knocking them into his bow like arrows. Its so absurd it should be funny.
Whats not funny is a dude shooting four roses at your group and watching them go through a steel shield, through scale mail, and out the back of the guy who thought his shield would stop flowers. Just quick as you please planting a rosebush from 200 yards and putting holes in anyone in the way of it.
Elves may be overly committed to their nature theme, but that doesn't make them any less dangerous if you trespass into their glades or whatever.
