What to do with an agapanthus plant

Hi, do you know which species you have, there are about 10 species, some fully hardy, some only half hardy, I would expect it to be a hardy species, if the plant it's been taken from is planted outside in the garden, in which case I would plant it straight into the garden, a s a p, to get it more established before winter, Derek.

or pot up in a good compost [I use a mixture of John Innes no 3 and non peat based compost.] and keep it well watered and leave in a cold frame or unheated greenhouse. when you have a suitable place to plant it plant it out.

Many thanks
