The Canberra climate and soil seem to suit Agapanthus – you see them in a lot of gardens here. They’re originally from South Africa and seem to be loved and hated in equal measure. They grow relatively profusely but don’t take much/any looking after and reward you for your neglect with big blooms of blue or white flowers throughout summer
We had a large space by our back fence in need of brightening up and I was given (via freecycle) about 20 agapanthus plants. I wasn’t sure if they’d flower in their ‘first’year – they haven’t all – some of the smaller plants obviously need a bit more ignoring before they prosper, but about 6 or 7 have got lovely flowers on them.
