didn't do anything

Submitted 1 year ago

I tried these twice in the spring. I planted them pretty soon after I got them, and they didn't do anything. They didn't even try to sprout. This was disappointing.

Received two tubers and one sprouted and the other one didn't. Had my doubts as they arrived looking desiccated. The one that sprouted never grew to more than an inch high. Wouldn't recommend.
