Three O'Clock Flower

[Knight of Albion]

I was just thinking back to my childhood. In the summer my mother and I often used to 'walk' the garden. There was one particular plant we always visited, remarkable because it closed its petals at three o'clock ....
It was a small little plant (native) and I'm pretty sure it was light blue in colour - though my memory might be awry there. Anyone got any ideas what it might have been?

Possibly/probably what was known as Mesembryanthemum (Livingstone daisy) back in the day, can't think of it's new name though Or Osteospermum (Cape Daisy) very similar habit

Thank you, dear BB. No, it wasn't that. It was a tiny flower. Having had a hunt round, Pimpernel is a possible contender, but that's red and I remember the flowers as being blue

Mirabilis Jalapa is known as the 4 o'clock plant . Could this be it on summer time
