Care & Maintenance
E. maculatum is a native prairie plant that thrives best in average to moist locations. This species can easily be propagated by division, seed or stem cuttings. If growing from seed, it may need to undergo a cold, moist treatment for 4-6 weeks. Transplanting in the spring can also be done. Fertilization will be of some benefit as well as staking for support. Pruning, or cutbacks, in early summer may reduce the final plant height by a few feet to make a more manageable size. In borders, the plant may need dividing every few years to maintain vigor.
Usually blooms from August-September. Flowers attract butterflies and the foliage provides food for some species of moth caterpillars.
