Those are a pass along amaryllis from the neighborhood. Literally every yard has some or we make sure to pass some along to the undecorated yards :-)

The obedient plant ended up being a phlox.

Mine are blooming too. Just like yours!

So pretty!

Well I do know that one spring, after a really cold winter and even later cold temperatures, my amaryllis bulbs that had been doing well for several years didn't grow. I gave it enough time to show some signs of life, then I checked the pot, and there was nothing there. When it turns to mush, it really turns to mush!

I've grown my amaryllis collection from clearance sales and from friends who didn't want to take care of the plant after it finished blooming (indoors, usually).

Purslane, that's probably what happened to my bucket of amaryllis bulbs. They turned to mush and then to compost so that when I emptied the bucket much later I saw only soil. Thank you for the insight.
