Bring a tropical look to your garden with Hibiscus × 'Summerific® Berry Awesome' (Rose Mallow 'Summerific® Berry Awesome'), a hardy, herbaceous hibiscus that returns each year from the roots. You will get a dense, upright, shrub-like clump topped and filled with huge, ruffled flowers through the heart of summer into early fall. Expect mature height around 36-48 inches, with room to spread about 48-60 inches wide for best performance.
Give it full sun for the strongest stems and maximum flowering, though it will tolerate part shade (especially in hotter climates). Plant in rich, moisture-retentive soil that still drains well, and keep watering consistent during heat for the largest blooms and lush growth. This is a great choice for borders, mixed beds, and as a focal point in sunny landscapes; it also works well where soil stays evenly moist, such as near downspouts, low areas, or rain-garden edges.
Hardy hibiscus is slow to wake up in spring, so be patient as your other perennials start growing. Leave stems standing through winter if you like, then cut them back in early spring before new shoots appear. A thick mulch the first winter helps the plant settle in, and renewing mulch each year helps keep roots cool and soil moisture steady. Space plants so air can move through the clump and remove spent flower petals as needed for a tidy look.
