Last year a coleus volunteer popped up in a pot of Crinum Menehune that lives with the bottom few inches of the pot submerged in a small pond. I removed that pot from the water for the winter months and the coleus disappeared so I assumed it froze and died. However, it is back in that Crinum pot and bigger than ever. Almost looks like a Kong but I have never had any of those around. Stands about 30" from the top of the pot.
