Daughter here in San Diego has just one comfrey plant, no stalk to it, just a bunch of leaves. I don't have much of a clue, but Is this a bocking 14 or something ?
she's terrified it will spread like wildfire if she puts it out in her garden.
Will it ?

Unfortunately, Comfrey is indeed a thug. If she can contain it somehow, it's useful stuff for making liquid feed, but I inherited it and I can't get rid of it, no matter how I try. BE WARNED!!!!!!
