I have a policy of letting unknown plants in my garden grow until I can identify them --- it makes it easier to know weeds when they're young if I can see what they grow into. The following has me stumped; details:
- It's grown into a 6' behemoth with extremely fuzzy/furry leaves and stem/trunk
- It sprouted tiny purple flowers last week
- It is maybe nine months old, but most of the growth has taken place in the last month or so
- I live near downtown Los Angeles
Based on its general structure I'm guessing it's some sort of tropical, but I have no solid knowledge one way or the other.
