What is the most unusual non home-grown plant that you own contained by your garden?
Unusual / non native plant to what nouns? you left yourself yawning open on that cross-question. I would try a Passion plant/ flower. native to Hawaii and furnace areas than the north, nice flower with eatable fruit.
I adjectives a Grevillea robusta when I moved in. It's in the region of as tall as surrounded by this picture and just started flowering. It's an Australia home-grown and I'm in California.

Answers: Maple Tree, and I am in se Louisiana. We found it alongside a road, brought it home and planted it. People said that type would not grow so close to the gulf. That be about 18 years ago. It's huge! The type you usually see up north.
