Lantana. This is my kind of plant.
Yes, it's growing out of a railroad tie. Months ago, I pulled a railroad tie from the slope above to mark the border between a planting bed and the children's play set. (Crap, it has a weed growing in it.)
This is where the railroad tie was pulled from. That parent plant, I guess that's the right term, was pruned far back this year, as it was getting quite leggy. The baby Lantana in the railroad tie gets no a) water, b) fertilizer or c) care of any type. Yet, it grows. That's my kind of plant. Now, if only tomatoes could be like that.
