How many Agapanthus in a pot??

I have a dilemma I'm trying to get to the bottom of but can't seem to get a clear answer anywhere. I have 12 Agapanthus corms/bulbs that I want to pot up soon but I cannot for the life of me figure out how many I should plant in for example a 30cm pot. 
Obviously I've looked on the back of the packet and it says to keep them 25cm apart but then I would need 12 x 30cm pots! I also read somewhere else that 3-5 corms to a 30cm pot is perfect as they like to be crowded. Can anyone help??

    Put them all in one pot for now, in a couple of years  when they’ve grown on you can always split them if necessary.

    Hi Lyn,

    Thanks for your reply. Do you actually mean ALL 12 corms in one single 30cm pot?! That seems an awful lot in one place. But like they say, agapanthus like to be crowded so perhaps give it a go.

    I think 3 per 30cm pot is a good place to start.  Give them John Innes loam based compost rather than multi-purpose as they don't like to sit with wet feet.   Leave them in those pots till they're positively bursting to get out.  Just make sure you feed them slow release fertiliser every spring and give an occasional drink of liquid tomato food but really, not too much, as they are better off treated a bit mean.

    Take the pots into a frost free place for over-wintering.

    Thanks Obelixx, 3 per pot sounds a bit more realistic I think. And thanks for the tip on how to care for them too, much appreciated. Just one more question... do you soak the corms for a little while before you plant them?

    I am a bit concerned about what you say, because Agapanthus don't grow from corms.

    Well, crown, corm, bulb... not sure what to call them, have seen them be called all three so I just picked one :)

    Techincally, I believe they are rhizomatous rooted plants but not as obviously so as say bearded iris.   If the root parts look very dry then yes, soak for an hour in cold water to rehydrate them.

    Have a look at this info from the RHS on growing them - https://www.rhs.org.uk/advice/profile?PID=60

    I meant the 3 to 5 as you said.

    There are different varieties of Agapanthus. They all grow outwards into clumps but some are much bigger than others. I haven't found that mine prefer to be crowded but they all become crowded and can be a real challenge to get out of the pot and divided. Therefore, I would use your personal judgement in planting them and avoid potential overcrowding in a very short time.

    If you're on freecycle, you might be able to get some extra pots
