Helianthus Nuttallii 20 Seeds – Marsh Sunflower Native Tall Yellow Wildflower

Helianthus nuttallii, commonly known as marsh sunflower or Nuttall's sunflower, is a tall, native perennial wildflower that brings bright yellow blooms to wet and moist landscapes. This robust sunflower is well-suited to rain gardens, pollinator gardens, and naturalized areas where its late-season flowers support bees, butterflies, and other beneficial insects.

Marsh sunflower offers a wild, meadow-like presence with its upright stems and cheerful daisy-like flowers. It is a valuable choice for native plantings, restoration projects, and low-maintenance borders that can accommodate its spreading habit and preference for consistent moisture.

Planting & Care

Sow Helianthus nuttallii seeds indoors or directly in the garden after the danger of frost has passed. Lightly press seeds into the soil surface and keep them consistently moist; do not bury them deeply, as light aids germination. For best results, stratify seeds by cold-moist chilling for 30 to 60 days before sowing. Germination can be variable, so patience and even moisture are key.

Once seedlings are established, transplant them into a sunny location with moist, fertile soil. Water regularly during the first growing season to help roots settle. Mature plants are relatively low-maintenance but benefit from occasional division to control spread. Cut back stems in late fall or early spring to tidy the garden and encourage fresh growth.
