I'm going to venture a guess and say they're both tropical...
Copied from a hibiscus site
In general, tropical hibiscus leaves are dark green and glossy, and those on hardy hibiscus are medium green and heart-shaped. This isn't always the case, however. The leaves on the hardy species Confederate rose (Hibiscus mutabilis), for example, are large and lobed (not heart-shaped). Those on hardy Swamp rosemallow (Hibiscus grandiflorus) are fuzzy and grayish green and on "Kopper King" reddish. The tropical Mokulei rosemallow (Hibiscus brackenridgei) can have a gray or silverlike leaves.
