....just back from France and saw the most gorgeous plant/shrub there which I have some seeds from in an attempt to grow here. I fear its tender though as I haven't seen any here.
The flowers are reminiscent of a very small iris or orchid, and come in a variety of colours, the ones I have seeds of have a pink outer and paler pink midrib. The leaves are a mid green ovate shape. When the flowers are over, if you pinch the base very gently, the whole pod curls up and releases its seeds.
It seemed to have a number of stems, not really woody so prob a perennial rather than shrub and was about 4ft.
I do have loads of pictures but am such a complete technophobe I can't post, I'm afraid. Any ideas as to what it may be appreciated.
