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.

|I have lots of evening primrose flowers in my garden. Next time I look at them when the sun will come down, I will remember what you have taught me about photonasty. Very interesting.|

When I first grew the Evening Primrose I was unable to identify the first year flat rosette. I sent a message to Green Deane of "Eat the Weeds" and he was kind enough to send me a photo to help me identify which rosettes in my yard were weeds needing to be pulled and which were the Oenothera. After that I took photos like this one to help me remember:
It is amazing to me how these flowered open in the blink of an eye just at sunset. I remembered to have my camera with me just as the sun went down below the trees and got this shot:
