Phlox paniculata 'Roberta' - 2026

Phlox paniculata 'Roberta' is an upright, clump-forming perennial with glossy dark green leaves. From midsummer into early autumn, it produces dense clusters of red-purple, fragrant flowers. These blooms attract bees and butterflies while adding vibrant colour and ecological value to borders, cottage gardens, and mixed perennial beds.

Thriving in fertile, moist but well-drained soil, 'Roberta' prefers full sun to partial shade. Regular deadheading of spent flowers encourages continued flowering and helps maintain a tidy habit. Phlox paniculata 'Roberta' combines bold colour, fragrance, and wildlife support, making it a rewarding choice for UK gardens.
