I had one of the native delphinium (Delphinium carolinianum) that I wild collected...
The voles got it last winter.
I had more problems keeping that plant going...
The rabbits made a habit of chewing off the bloom spikes, so I put a little fence (cage) around it.... that kept it going for a couple years... Unfortunately the fence didn't extend underground.
I had a seedling in a pot... but it's awful hot and dry here in the sandhills... I think I lost that seedling when I wasn't looking.
