Patrinia triloba
An eastern valerian with trilobed foliage creating fine-textured mounds. Small yellow flowers appear in loose, branched clusters on slender stems. The fragrant blooms and delicate appearance belie the plant's toughness. Provides valuable late-season interest.
Underrepresented in gardens despite ornamental merit. Thrives in sun with well-drained soil. The late flowering period extends the garden season. The fragrance is a notable feature. Combines well with grasses and late perennials. Still relatively rare in cultivation but deserving of wider use.
