Thanks very much. That's it (Portulaca grandiflora) It looked just like this picture:

I do the same thing, Jim. I have been cutting all the seeds off so the plant will bloom longer, but plan to stop doing that soon, so there will be seeds. Each pod will have quite a lot of seeds. I have trouble getting them to germinate usually. Last year I was gone for a month, and came home to LOTS of seed pods on my yellow Datura (moonflower), so I cut them off and just threw them in a bucket that had holes in the bottom. NO DIRT. I thought I would discard them, but neglected to do so. This spring the 3/4 full bucket of seeds started to sprout! I just took the plants out and put them in dirt and more would sprout! There are still seeds in that bucket sprouting as I type. I guess when I don't try I get better results! LOL My white one doesn't have as many seeds, or blooms, as the yellow one, or the purple one. This year I may have a bucket for each color! Grin!

Ranunculus repens or Ranunculus acris? Can't see leaf clearly.

"The cells of the Dieffenbachia plant contain needle-shaped calcium oxalate crystals called raphides. If a leaf is chewed, these crystals can cause a temporary burning sensation and erythema. In rare cases, edema of tissues exposed to the plant has been reported. Mastication and ingestion generally result in only mild symptoms.[11]" "Many plants accumulate calcium oxalate as it has been reported in more than 1000 different genera of plants.[2] ... It is also found in rhubarb (in large quantities in the leaves), cinnamon, turmeric and in species of Oxalis, Araceae, Arum Italicum, taro, kiwifruit, tea leaves, ... and in spinach in varying amounts. ✔ ✔
