planting around a french drain
I am putting a patio in an area where my yard slopes slightly *toward* the patio, and one corner of the patio will be in the spot where water tends to collect after a rain.
So, I have researched french drains and it is all laid out and designed. I want to create a nice, slightly curving, rocky area around the patio for a) a nice effect and b) to disguise where the french drain is.
Let's assume that the patio and french drain are designed correctly, because I did review this with an architect friend (who is NOT a gardener).
My question is this - Should I line the trench with landscape fabric (like most plans recommend) or should I just fill the trench with (approx) 12 inches of rock and plant away?
Should I avoid plants with thick, fiberous roots and choose plants with nice deep tap roots? What is best for contributing to fast absorption into the soil?
My other option is to skip direct planting altogether and use potted plants and sculpture for decoration.
(No pictures yet, still in design phase!)
