This is growing like crazy now and depending what it is, I might just plant this in my cactus garden.
It's growing all around my mailbox and has been for 3 or 4 years. I'm in the city however so if you're outside of town it may turn to mush most Winters though they return quickly in Spring. HTH Chris
