10 Seeds Inula racemosa Sonnenspeer Indian Elecampane Yellow Perennial Flower

Inula racemosa Sonnenspeer, commonly known as Indian Elecampane, is a robust herbaceous perennial prized for its tall, stately stems and bold, daisy-like yellow flowers. This cultivar brings late-season structure and warmth to borders, cottage gardens, and wildflower plantings, growing vigorously in a single season from seed. The sturdy, upright habit and large basal leaves make it a strong architectural accent, and its blooms open over a long window from midsummer into early autumn.
Grow it toward the back of a mixed border, in meadow-style plantings, or as a specimen where its height and color can be appreciated. The flowers work well in fresh arrangements, and spent heads can be left for textural interest into winter. It prefers consistent moisture and rewards a spot with room to spread.
