- Hosta 'Halcyon' (Plantain Lily) - Provides broad blue green foliage that complements the fine texture of fern fronds.
- Brunnera macrophylla 'Jack Frost' (Siberian Bugloss) - Brightens shaded areas with silvery foliage beneath the taller fern growth.
- Iris versicolor (Blue Flag Iris) - Adds vertical form and colorful blooms suited to similarly moist growing conditions.
- Tiarella cordifolia (Foamflower) - Creates a low growing ground layer with delicate flowers that softens the fern’s larger structure.
