Furthe agapanthus advice

Now that I am a convert to agapanthus and have two successfully flowering in pots, my friend has kindly given me the one in the photo. She has had it for a few years, but it has never flowered. However, it hasn't been kept in the sun and is just in general purpose compost. I am going to try and rectify this by repotting it into John Innes and grit, and placing it in full sun my sheltered patio. My questions are:
1. When should I do this?
2. Is there a way of telling if it is evergreen/deciduous, or even the variety?
3. Its leaves are very small, is this just because it has been in the wrong conditions?
4. Is there a way of telling its hardiness, or should I just fleece it over winter anyway, until it flowers?

I would be inclined to transfer it into the next size down pot, now, in John Innes and sharp grit, and place it in a sunny, sheltered position.
Probably not evergreen. Protect it from low temperatures. I keep mine in a cold greenhouse, I stand the pot on a polystyrene sheet as insulation and cover all with horticultural fleece. Let the pot stay dry overwinter.
Hopefully next year you may see some flower buds, which should help you to identify the variety.
I think the key, is good soil based compost, feed and water well.
for the fag ends of the aristocracy.
Yes, I was going to reduce the pot size as well. Just to check, I can do it now?

I believe the reason they don't flower is a lack of enough water AND fertilser AFTER flowering. This is when they make buds for next year's flowers ( in the same way we feed Daffodils after flowering )
Another "myth" is that they don't flower the year they're split. These were all split in February.
My guess is that your plant has used up all the nutrients in that pot so give it a weekly weak feed of tomato food until they die down in Autumn.
I'd say your plant is likely to be deciduous. General rule of thumb, the thinner the leaves, the more likely it is to be deciduous. Deciduous hybrids are much hardier than evergreen types.
Depending on your location they're usually hardy enough to be outdoors in winter . I only bring in the evergreen plants in the above photos into the polytunnel for winter. I planted out about 40 deciduous plants in the garden this year.
What did the roots look like?
