Baptisia (page 2 of 2)
by Susan Littlefield
Unlike many other perennials, baptisia clumps don't need dividing. Although it's possible to divide the deep, gnarly root mass, it's risky and you may end up damaging the plant so much that it can't recover. If you want more plants you can propagate it by seed (though it is slow-growing and will take years to reach an appreciable size.) It has few insect and disease problems and is usually ignored by deer.
You can shear back established clumps by one-third after bloom is finished to control size somewhat and make flopping foliage less likely.
