Baptisia, also called false indigo, is an herbaceous perennial shrub that performs well in our hot and humid summers. Recent breeding efforts have expanded the range of flower colors requiring a new look into an old favorite. I myself have falling in love with two top performers according to Mt. Cuba Center’s 15-page report, Baptisia for the Mid-Atlantic Region. The Mt. Cuba Center’s Trial Garden, managed by George Coombs, research horticulturist, evaluates native plants and their related cultivars. From 2012 to 2015, staff evaluated 46 selections of Baptisia including representatives from 11 species to determine which performs best in the mid-Atlantic region. Over 60 percent of the plants tested receive 4 or 5 stars. Among those, 10 superior cultivars outperformed the rest. Fortunately for me my two recent Baptisia additions to my garden are included in the ten.
This year I acquired two Lemon Meringue and two Dutch Chocolate plants. They are small now so a photo won’t give you the full flavor of their beautiful flowers but I was able to borrow Proven Winners‘ photos of what my plants should look like when they grow up. Baptisia plants die back every fall and comes back in the spring. By summer, the plants will have grown to their mature height of about 3 x 3 feet each year. However, they do not like to be moved so give them plenty of space when you do plant them. Chances are the nursery plants will be young thus small but they will grow into full bushes once established in the garden. In May, pea-like flowers bloom on tall spikes, similar to lupines. In the fall, pods appear, which can be used for dried flower arrangements. Baptisia plants are deer resistant, heat and humidity tolerant, and drought tolerant once established. These natives make great additions to the garden and the new cultivars increases the color selection.
