MadCow expounded:

It covers other perennials rather than the ground, and it wouldn't cover
anything very well because it has no chlorophyll so it lets the light
through.

I really should have taken a picture of it before I started to battle
it - it was a woven mass of yellow with green sprouting through. Very
odd and very determined...
