Hello Denis :-)

Great pic, thanks :-) Lovely lilac colored one !!! Is it an odorata (cultivar)or a wild suavis ?
I think the white one with a touch of purple on the lower petal must be C'zar white, mustn't it ? Anyway, that's the name it's given when it's sold here in Lyon ;o)

Cordialement.

Oh, I'd have been camping on the grass, scrounging around for seeds to bring back home - of course plants too if I could! Especially if they were fragrant! Its always a good idea to travel with a spoon - just in case one has to mmmm pop one out of the soil into ones pocket! :)
