100 Seeds Siberian Wallflower Cheiranthus allionii Wildflower Pollinator Cottage Garden

Siberian Wallflower (Cheiranthus allionii) is a hardy biennial wildflower prized for its dense clusters of fragrant, bright orange blooms that light up the spring garden. A favorite in cottage gardens, meadow plantings, and border edges, it delivers bold early-season color with minimal fuss and pairs beautifully with other low-growing wildflowers.

These plants are versatile in the landscape, working well in pollinator gardens, naturalized areas, rock gardens, and containers. The flowers are long-lasting when cut, and the compact, mounding foliage stays tidy through the season. Plants typically bloom in their second year, then readily self-seed to carry the display forward.
