If you want a bold, tropical look that survives winter, Hibiscus × 'Summerific® Evening Rose' delivers. This hardy, herbaceous hibiscus (rose mallow type) dies back to the ground each fall and returns from the roots in spring, building a tall, full plant topped with dinner-plate sized blooms in mid to late summer.
Give it full sun for the best flowering, though it can handle part shade, especially where summers are hot. Plant it in rich, moisture-retentive, well-drained soil and keep watering steady during dry spells for the largest flowers and best performance. A layer of mulch helps conserve moisture and keeps the root zone comfortable.
At maturity, plan on about 48-60 inches tall with a broad, substantial presence in the border. Space plants so the clump has room to fill out, and site it where you can enjoy the dramatic contrast of bright blooms against dark foliage. In late fall or early spring, cut the stems back to near ground level and let the new growth take over for the season.
