I'm late getting here. Sorry.
I love surprise plants and it seems that is what you got, Cinta! Two years is a long time!
I love the color too! My favorites are the hot pinks and bright oranges.
When I over wintered a pot of Purslane it did wonderfully up until the sun changed course. I should have moved the plant to another window. It never died, but eventually thrived again. So keep yours with a lot of sunshine.
The seeds that flew off into the soil took over and gave me summer after summer of beautiful, abundant growth in my former garden.
