PP#20013, Scrophulariaceae
Simple to grow in full sun, ordinary, dry to medium, well-drained soils. Plants can withstand summer heat, drought, and humidity to some extent. Steer clear of soggy, poorly drained soils. To extend bloom, remove spent flowering racemes. After flowering, plants can be pruned back to their basal leaves to enhance the planting's appearance. A loose winter mulch is frequently beneficial to plants in cold winter climes.
