Explanations of How Plants Respond to LightExplanations of How Plants Respond to Light

I couldn't figure out why one of my plants looked parched/dry/thirsty even though I had watered the day before. Research tells me this plant is exhibiting a "nyctinastic" response to approaching night. The plant knew when it was day and when it was night, folded its leaves, and appeared to be napping. Wow, a nyctinastic response is fantastic. Do plants sleep? Yes, and they do a whole lot more. There are several types of nastic responses in the plant world.

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).

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

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.
