I took the photos in the dark with a flash which has altered the colours somewhat. The flowers are brighter pink and the leaves are darker green with a brown tint. The leaf stems are a reddish-browny colour. The plant is about 1m tall, just under, and is spreading through underground suckers. The bruised leaves have an unpleasant smell. Or at least it is unpleasant to me and reminds me of the same smell from another plant that I can't remember.
