    When touched, leaflets fold up in a most spectacular fashion, leaf stalks drop as if they were hinged.
    Huge success w/ kids.
    Bloom looks like a puff-ball about an inch across.
    Sometimes self-sows here in Z5b; seed is easily collected at maturity (brown seed pods).

    I planted a rooted piece of this 5 years ago in a part-sun flowerbed that gets moisture from the drip line of the roof and saturation when it rains. It has thrived and sent runners to now cover the 8' bed, to the point that I now have to trim it to keep it in bounds.. It is in bloom now, July 2018. I'm in zone 9 and it goes dormant in winter. It took the unusual 21-degree lowest temp of 2017/2018. It stays low and neat, and the pink wand flowers are a sight to see when in full bloom. Children and adults love this curiosity plant.

    Highly invasive in Australia; a declared pest in Western Australia. It is a good example of thigmonasty or seismonasty.
