There are several Hibiscus species that will grow in Utah and survive the winter. One is the very common Rose of Sharon (Hibiscus syriacus). This water wise shrub is grown easily in Northern Utah and there are many varieties with flowers mostly in white, pink, dark pink and blue. Rose of Sharon blooms in late summer and fall providing excellent color in August, September and October.
There are also some smaller perennial Hibiscus (species too numerous to mention here. Plant Delights catalogue has a good selection) that grow well in Utah and have huge flowers in September and October. White or pink or red tropical-looking flowers that are 6 or 8 inches in diameter can be quite striking to see on a September day!!
