Growing Spiderwort: Full sun to full shade. More compact, heavy blooming in sun, flowers brighter in shade, growth more lax. Tolerates wide range of soils and average water. Prefers ample water, tolerates wet soils. Cut back hard after bloom; keeps plants neat, encourages repeat bloom in autumn. Manage spread by dividing plants every 2-4 years, and by removing lax stems that can root in soil. Rarely bothered by pests or disease. Flowers attract butterflies.
