The purpose of cacti

zelda-skyward-sword

Lanayru Desert is covered with cacti. I realize they hold bombs at a nice height for the beetle to pick them, but do they have another purpose? You can bash on them and get the bark off, but can you destroy them? Do they hide anything valuable?

Best Answer

If you hit the red bulb-like object on top of the non-bomb cacti, they provide a heart. Besides this and providing bombs for the beetle, there isn't really much purpose to them.
