Compact shrub for a pot in full sun?
I would like an elegant, wafty-scented, ideally evergreen, white long-flowering shrub to go in a 50x60cm heavy pot, near a seating area. It would need to tolerate alkaline/neutral soil and hard water. It needs to be tough enough to take a baking without frying. I can shade the pot a bit but the plant would be in full sun. Singing and dancing beneficial but not essential.
Abelia Grandiflora seems to fit the bill, but the scent is a bit light and not very wafty. I have this one below, planted in poor soil and rarely watered, which I think is a grandiflora... but have you lovely folks got any other suggestions for me?.

Daphne 'Eternal Fragrance'?
I have one in full sun in the soil just outside my back door and it is thriving.

I think the Choisya is a distinct possibility, @Obelixx - somehow I had it in my head that Choisyas needed acid conditions but RHS says not, so I must have confused it with something else. How do you pronounce choisya by the way?!
Unless I'm speaking French.

There is a nice low growing Pittosporum called Pittosporum Tobira 'Nanum' that does well in full sun. White flowers that fade to a creamy yellow in late spring into summer.
I saw in late spring this year the wax flower shrub, Philotheca Myoporoides for the first time in the garden centre, and even when not in flower, the leaves were interesting. I was told it would do well in large containers. Not fully hardy in harsh frost, but can easily survive if tucked against a southerly wall. Sadly I had no more space, but it's on my wish list.
White Dazzler and the Aztec Good look good, as does the Philotheca. All are available mail order from France as is the Daphne.
That’s given me a good list to hunt down locally first, as it would be good to see them in the flesh. Thanks everyone.
I am in SW France and I have Choisya Aztec Pearl in a bed that is never watered. I have alkali soil. I prefer its green leaves to the gold ones. Good to know it can be grown in a pot. I have given up on Daphnes, I think it is just too hot here in summer. It was 40° for more than one day on 3 occasions this summer. Several shrubs and roses had burnt leaves.
I'm glad Nollie asked the question as I am spending more time in the UK as my partner lives there, so I will be changing the garden and instead of planting bedding plants in pots I'm thinking of lavender, perovskia, purple sage etc instead. The housesitter is getting expensive! But I will have to put my elderly mare in livery.
