Buying rhizomes

I’m looking to plant my first rhizomes this year. I live in southern Cal and hoping to have a long growing season. I’d like to purchase and plant as soon as possible but can’t seem to find anyone with rhizomes to sell until March. Does anyone know where I can get some earlier than that?

Thank you!

I’m sure you would need to find a supplier in southern California. here in MN the ground is frozen solid till mid March.

Also, you will have a long growing season regardless since it is southern California.
