I believe the answer is:

plant pot

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

'container' is the definition.
(I know that plant pot is a type of container)

'little one filled with primroses initially on plot' is the wordplay.
'little one' becomes 'tot' (I've seen this in another clue).
'filled with' indicates putting letters inside.
'initially' suggests taking the first letters.
'on' means one lot of letters go next to another.
'plot' becomes 'plan' (I've seen this before).
The initial letter of 'primroses' is 'p'.
'tot' enclosing 'p' is 'tpot'.
'tpot' put after 'plan' is 'PLANT-POT'.

'for flowers' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
