Blue Paradise - Tall Phlox

Blue Paradise is a clump-forming perennial phlox with fragrant violet-blue flowers and a dark eye. The RHS profile describes plants reaching about 1.2 m tall and 0.1–0.5 m wide, with flowers from July through September. Grow it in full sun or partial shade in fertile soil that remains moist while draining freely. Its upright flower stems and cool-toned blooms work well in a sunny border or a mixed planting with later-summer perennials. The listed size is for the RHS profile; actual height and spread vary with climate, soil, and care. See the [RHS Blue Paradise profile](https://www.rhs.org.uk/plants/50575/phlox-paniculata-blue-paradise/details) for selection-specific details and the [RHS tall garden phlox guide](https://www.rhs.org.uk/plants/12736/phlox-paniculata/details) for general growing conditions. ## Maintenance Water during dry periods and keep the soil from becoming waterlogged. Remove faded clusters to keep the border neat, then cut back old stems after flowering or in spring.
