Mirabilis jalapa/four o'clock

I can't identify, but I can tell you that a glass cup is not a good container for it. The glass makes the media get too hot, and it should be dark below the surface anyway. Also, a lack of drain holes is usually problematic. Do you have a different pot? Maybe a small terra-cotta?

Hi Gina, no apologies needed:-) people her will chime in on the IDs, it's not a pain at all, and the list is a little less active because it's JUNE, yay, we are all out in the dirt:-) if you don't get a response soon, try this: repost your photos with numbers and just a short request for ID's. That makes it easier for folks to answer. usually you'll get several responses, with each person just IDing a couple plants, rather than one person doing it all. The numbers help make it easier for several folks to each focus on what they know best.

The picture I posted doesn't have the blossoms open, but I'm thinking it is the Conoclinum coelinium. Plus, you can't really tell from the picture I posted, but it is purple. Thanks peren.all! I don't understand why it just totally disappeared from that little area. It was a spread about 5'x3'. Could it just have gotten too crowded? I really want it back, since it was from my MIL, who I really loved. Thanks!
