I grabbed these from Lowe's today. I'm pretty sure they're Pinguicula primuliflora.
The largest one may have a chance; the medium-sized one has stubs for roots and will probably die.
The tiny cluster was a "bonus" in the package.
I haven't grown butterworts yet, but I followed what the Savage Garden had to say about soil, watering, etc.
Is there anything specific I can do to try to revive these pings?
