Hibiscus 'Watermelon Ruffles': Ruffled Magenta So Big It Looks Fake

Where to Plant: Give it a spot where people will see it: the back of a sunny border, a corner by the patio, or the middle of a bed as a focal point. One plant fills a lot of space by midsummer, so it also works as a seasonal screen. It doesn't mind moist ground, which makes it a good fit for a low spot or the edge of a rain garden.

Companion Plants: Perovskia 'Denim 'n Lace' matches its bloom time, with blue spires at 70 to 80 cm from July into mid-fall. Anaphalis margaritacea 'New Snow' adds white flowers at 45 to 60 cm from July to September. Aster 'October Skies' takes over in September and October with lavender flowers on a compact 45 to 60 cm plant. All three love full sun, the same as this rose mallow.

Plant Care: Plant it in full sun, in rich soil that stays evenly moist. Hardy hibiscus copes with heavy clay better than many perennials, but it sulks if it dries out, so water deeply in dry spells, especially in its first summer. Be patient in spring. Hardy hibiscus is one of the last perennials to wake up, often not showing new shoots until late May or June. Mark its spot so nobody digs into it by mistake. Cut the old woody stems down to about 10–15 cm after a hard frost or in early spring. It grows from a tough crown and rarely needs dividing. Watch for Japanese beetles and hibiscus sawfly, which may chew the leaves in summer.

History: Hardy hibiscus hybrids come mainly from Hibiscus moscheutos and its relatives, wildflowers of marshes and riverbanks in eastern North America that reach north into southern Ontario wetlands. The breeder of 'Watermelon Ruffles' could not be confirmed from a reliable source.

Final Thoughts: Full sun, a hot spot and zero patience for fussing. Plant it and spit the seeds at the competition. SUMMER, SERVED CHILLED.
