Growing Lysimachia (Gooseneck Loosestrife): Showy Perennials for Moist Soil

About Loosestrife

Large attractive group: tall with arching spikes or ground-cover stature. Prefer moist soils where most spread rapidly. Many garden species are more restrained; long-blooming flowers essential for summer borders/bouquets.

Care

• Light/Water: Full sun or part shade. Water thoroughly after planting; weekly soak first week, then weekly in summer unless rain >1″. Established prefer even moisture.
• Soil/Fertilizer: Not fussy. Prefers moist well-drained but tolerates poor drainage; less vigorous/invasive in dry soil. No fertilizer at planting or first year. Established: light balanced granular (10-10-10 or organic) once in early spring.
• Maintenance: Tall species may need staking. Deadhead to prevent seedlings. Divide spring or fall. Pests rare; occasional rust/leaf spot.
