Can I bring my Portulaca plant in the house for the winter?
You can try but these plants are annuals and likely will not return. That said, you can collect seeds and grow new ones for next year.

When I try to start portulaca seeds, they germinate fine. After they get a couple leaves (1/2 inch tall), they all die. What are the tricks to starting portulacas indoors?
It actually sounds like your seedlings are suffering from damping off. This article will tell you more about it and how to fix it:
I live in a small town in the mid north of South Australia. The garden gets full sun. I planted portulaca along the front row of the garden. Every 2nd plant is all snapped off at the base. Also, my ranunculus leaves that were sprouting look as though they have been broken off. What is going on with my garden?? Malicious person?? My cat?? I don't know :(
You have a mystery! I'm not sure, but I suspect a rabbit may be snapping off your plants, especially if the breaks are clean. If not a rabbit, possibly some other type of wildlife.

I usually plant portulaca in a pot. I'd like to plant something else in the pot. Any suggestions for what to pot with it?
When you put more than 1 plant variety in a pot, the important thing is to make sure they have the same water, light, and soil requirements. So you want to look for plants that do well light soil, with not too much water, and good sunlight. Using these requirements, there are literally hundreds of choices. I suggest you visit some plant stores near you, to see what's available.

Contact your vet if you animal ingests these plants or any plant they should not be eating.
