Most hibiscus are single hibiscus with 5 leaves. Thanks to modern cultivation techniques, some varieties can produce flowers with more than five petals – called “double hibiscus” – in a dazzling array of colors, sizes, and shapes. They grow in semi-tropical and tropical growing zones here in the U. S. (zones 9 to 11)
A couple of weeks ago I shared peach double hibiscus blooming in the back yard after a rain here in central Florida. When the northern states got snow last week, we got a cooler front with rain.
