Experts and BHG readers answer.
Well having your garden flooded will cause damage to some plants. If I were you, I'd think about planting perennials that don't mind being flooded occasionally. Plants such as perennial lobelia, Cardinal flower, actually thrive in moist soil. Go to the Plant Encyclopedia on BHG.com and do an Advanced Search on wet soil and you should get some results. If not, re-post your question and we'll give you some additional recommendations.
