Planting over a french drain
Along the side of my house is a concrete border. Between the border and the house is about 3 feet covered with a thin layer of large gravel. I think there is a french drain underneath because the gutter drains into a black plastic drainpiece sticking out of the ground. There is some dirt under the gravel.
I want to plant New Gold Lantana over it(the kind that doesn't spread like crazy).
Would this cause problems for the drain? Should I plant something else?
