I rarely go to Mr. Yogato anymore--I planted a bunch of stuff that can take care of itself last year when I moved to Saudi Arabia. The spearmint is quite invasive, the herbs don't mind long dry periods, and the rest of it will either die or thrive. Natural selection in a public garden. I occasionally stop by to check things out, but I haven't watered or done much maintenance in more than a year.
Here is, perhaps, a better view of how expansive the vine is. (Please ignore the two girls on a speaker-phone conference call with another girl talking about who's taking whom to some wedding this summer. I tried my hardest to.)
