Verges on using gravity in seed dispersal (5)

Ross

I believe the answer is:

edges

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

'verges on' is the definition.
'edges' can be an answer for 'verges' (I've seen this in another clue). I'm unsure of the 'on' bit.

'gravity in seed dispersal' is the wordplay.
'gravity' becomes 'g'.
'in' means one lot of letters goes inside another.
'dispersal' indicates anagramming the letters.
'seed' anagrammed gives 'edes'.
'g' placed into 'edes' is 'EDGES'.

'using' is the link.

Can you help me to learn more?

(Other definitions for edges that I've seen before include "Bounds" , "Margins" , "They're farthest from the middle" , "Outside limits" , "Slowly moves" .)
