Answer: Your Physostegia will have spike-like clusters of lavender-white 1" tubular flowers in August, leaves 4" long at base of plant, average (moist to dry) soil, sun to part shade, spreads well, 2-3' tall. If the flowers are moved on the stem to face a different direction, they stay in the new position - hence the name 'Obedience plant'.
If the plants are vigorously growing, I wouldn't be too concerned about the dots on the leaves. Be sure to check the undersides to make sure there are no rust spores (fungal disease) that might be causing yellow dots on the surface.
