Answer: Planting a tree or a shrub probably won't reduce the amount of water that collects in the low spot, but planting something with a high tolerance for soggy soil will at least make the area look attractive. Some shrubs to consider:
Andromeda (Bog Rosemary); Cornus stolonifera (Shrub Dogwood);
Chaenomoles (Flowering Quince); Potentilla fructicosa (Potentilla);
Chionanthus (Fringe Tree); Sambucus canadensis (American Elderberry);
Clethra (Summersweet); Viburnum opulus (Snowball Bush).
Trees that tolerate wet soils include:
Abies balsamea (Balsam Fir); Populus tremuloides (Quaking Aspen);
Acer rubrum (Red Maple); Salix (Willow);
Liquidambar (Sweet Gum); Sequoia sempervirens (Coast Redwood);
Nyssa sylvatica (Black Gum).
You might also consider installing a curtain drain in the area to reduce the amount of standing water.
Best wishes with your landscape!
