Fresh brush undergrowth (5)

I believe the answer is:

shrub

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

'undergrowth' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'fresh brush' is the wordplay.
'fresh' indicates an anagram (a fresh re-ordering of the letters).
'brush' anagrammed gives 'SHRUB'.

Can you help me to learn more?

(Other definitions for shrub that I've seen before include "Perhaps Heather" , "Mixed drink of rum, sugar, fruit-juice and spice" , "Drink of rum, fruit juice and spices" , "box, say" , "Low woody perennial type of plant" .)
