I have a drainage swale in my yard that stays wet for many days after a rain. this makes it difficult to mow and in one spot there is no grass growing. the flip side to that is, the soil is clay and when we have no rain it is dry, rock hard clay (mid atlantic region) I would like to put a ground cover in it that I don't have to mow and won't impede the drainage. I cant really find anything that will tolerate really wet and really dry and not invade surrounding areas. the area gets at least partial sun, some parts get full sun. just looking for suggestions of plants to research, even if its some one who is growing something in similar conditions.
