Rheum rhabarbarum 'Goliath' - 2026

Rheum rhabarbarum 'Goliath' is a vigorous perennial producing enormous, crinkled, deep green leaves and thick, edible red to green stems. In summer, it forms tall panicles of small greenish-white flowers, adding height and texture to borders or vegetable gardens. While primarily cultivated for its edible stems, its bold foliage also attracts pollinators and provides architectural interest in the garden. The impressive size and upright habit make it a striking feature in mixed plantings or near water features.

It thrives in full sun to partial shade in fertile, well-drained, moisture-retentive soil. Medium-maintenance, it benefits from regular watering and mulching to support its vigorous growth. Non-native to the UK, it is valued both for its practical edible stems and ornamental presence, creating a dramatic garden statement.
