non-orchid id needed

[orkie]

Hi,

I recently obtained this plant when my grandmother died. I am hoping someone can id it. It looks like a cross between a spider plant and Tillandsia to me, and it flowered at my grama's house last summer, flower reminded me a bit of a Tillandsia flower and was spiky and kind of purple/pink. It also has some serrations on the leaves you can see in the 2nd pic.

It's is planted in some general soil and I would like to replant, but since I can't id it, I'm not sure what would be best. It would mean a lot to me if I could keep this plant happy.

Thanks for any help.
