Full SunDahlia ‘Jean Marie’ is a dinnerplate decorative dahlia that commands attention with its rich purple blooms edged in crisp white. The flowers are fully double and impressively large, creating a dramatic contrast that’s both regal and refreshing. Despite their size, the blooms hold upright—even in rain—thanks to strong stems and a balanced form.

‘Jean Marie’ blooms massively mid summer until frost, and the more you cut, the more it flowers. Its long vase life and upright habit make it a favourite for both garden display and floral design. It thrives in moist but well-drained soil, and benefits from regular deadheading and staking in exposed areas.
