Nope not miniature...at least the ones I have seen. You are on the right track. Bonus points if you know the common name.
Nope...Sloth was closer This plant grew outside in my wooded backyard back east. It was a protected species (and probably still is).
These I am not sure about, they are nursery grown ( the flowers) looks like a strawberry in the second pic. The flowers maybe a domino.
How about this one? We found it up in the Sierras. I looked in a few books and did some surfing, but never found the name. Looked like it was from outer space.
I just did a search, and I came up with... lewisia pygmaea When it blooms its beautiful, looks like you stumbled upon it out of blooming season
