'Summer in Paradise' Rose Mallow starts blooming in July and produces enormous deep pink flowers through the rest of the summer. The blooms appear all over the green stems rather than just at the tips, making an impressive show. The centers of the cerise pink flowers are set off by deep red eyezones. 'Summer in Paradise' flourishes in wet sites, and adds a striking tropical note to bog gardens, bioswales and pond edges. From Walters Gardens.
