Leptotes unicolour in flower

[RosieC]

I only bought this tiny guy a week ago so can't claim credit for the bloom as it had two buds already... but at least it didn't blast and I get to enjoy this tiny flower.

It's on a tiny mount (the tag is almost bigger than the mount) and is such a cute little plant.

It opened a couple of days ago, anyone know how long the flowers last on these, I didn't know if it would only be a couple of days and was worried if I would get pic but it stayed open at least long enough for that.
