Following Umbrian's suggestion, we have split off the discussion following Mike's helpful comments about winter protection to a new topic in General Cultivation, which you can see by clicking here.

I love Plumbago capensis too.
I laughed at Fleur's post about the flowers clinging to one's hair and clothes. All during it's flowering period, I find myself sitting in my bath with little blue flowers floating on the water's surface.
Here is mine growing with Solanum rantonnetii.

Just looking back at some of the discussion points in this thread I noticed there was some discussion around the hardiness of the plant. Both my blue and white forms have pulled through after a week of very cold weather in January. They were both stripped of leaves and the exposed twigs on the blue form were killed off. Plumbago indica pulled through in a pot kept in a little plastic green house.

Daisy includes a photo of Plumbago capensis alongside Solanum rantonnetii. My Solanum r. was similarly burnt by the frost and ice and it too has come back. But so far no flowers, only leaves.

For the record, night time temperatures were below 0°C for around 10 days and reached -6°C several nights in the early hours of the morning. Daytime temperatures were around 2/3°C. Pretty low for Rome.
