Ask Mr. Smarty Plants

We have a very similar previous Mr. Smarty Plants answer for flowering plants under pine trees; it is, however, from Illinois. And, another one from New York, which also gives you instructions for using our National Suppliers Directory. So, we will use the same method detailed in the previous answers to find flowers that will grow in part shade, tolerate acidic soils and are native not only to North America but also to the area where they are to be grown; in your case, Elkhart County, IN. 

We will go to our Native Plant Database and, scrolling down the page to use the Combination Search, search on Indiana for the state, herbs (herbaceous blooming plants) for Habit, and "part shade" under Light Requirements. We will list some examples and you can go back to do your own search for different plants with different characteristics. Follow each plant link to our webpage on that plant to learn bloom times and colors, mature heights, soils preferred and soil moisture for that plant. We ave checked each plant on our list with the USDA Plant Profile Maps to make sure they are native to your area and therefore compatible with your climate, soils and rainfall.
