Hi, do theses plants come back every year? Where can I purchase the seeds for them? I received one for Easter and its deep purple I am not good at anything but planting seeds. Where on the plant are the seeds? Do I just throw out the plant and buy one next year. thank You Kindly

Hi and welcome! This is an annual plant so will not come back next year. Not sure if it will make seeds but they will be on the flower stems after the flowers are spent.

Is it warm enough outside for you to put it out? It may need to be pollinated to make seeds.

I got one to rebloom by cutting off the spent flowers as they went, then repotting, fertilizing and growing it outside.

If you're asking about the plants that are often called "Florist's Cineraria" or sometimes "Senecio," here's one source for seeds:

You can indeed collect seeds off the plants. And I think they may be perennial in warm areas. I overwintered a couple of plants once, but they were aphid magnets indoors!
