Plant some lentils (3)

I believe the answer is:

til

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

'plant' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'some lentils' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'TIL' is hidden in the letters of 'lentils'.

Can you help me to learn more?

(Another definition for til that I've seen is " Sesame".)

I've seen this clue in the Sydney Morning Herald.
