I have grown them in a south facing aspect but in a very windy site in heavy clay soil and they were very successful. (I needed to stake mine because of the wind)
I put mine in plastic pots with the bottoms cut off and a small slit in the side into the border, so they could experience the root constraint they seem to like while they got used to the open soil. All 9 doing well so far after 2 years!
I have always planted agapanthus in my boarder on basically a clay soil with normally good success. I would suggest planting a deciduous type as opposed to a evergreen as in my experience they seen to grow better in a boarder

Agapanthus require a good quality well drained soul and feed every 3 weeks with tomato feed. They are a beautiful but greedy plant IMO

I have , this very day, completed splitting mine ( about 60 ) . Mine are in pots, because I've not decided where to plant them yet.
I just use mpc compost due to cost which has enough food in it to last until summer gets under way, then , like Steve, I use tomato food.
The deciduous varieties tend to be hardier than the evergreen types.
I bought more plants from pine cottage plants ( one of the national collection holders )
