Curbs spread of low vegetation (5)

Ross

I believe the answer is:

scrub

I'm a little stuck... Click here to teach me more about this clue!

'low vegetation' is the definition.
'scrub' can be an answer for 'vegetation' (scrub is a kind of vegetation). I am not sure about the 'low' bit.

'curbs spread' is the wordplay.
'spread' is an anagram indicator.
'curbs' is an anagram of 'SCRUB'.

'of' is the link.

Can you help me to learn more?

(Other definitions for scrub that I've seen before include "plants" , "Cancel; clean vigorously" , "Powerful wash" , "Clean - scrap" , "Rub hard - low vegetation" .)
