How many different types of hibiscus are there?

Also question is, how do I know what kind of hibiscus I have?

Another way to check is if the flowers are salmon, peach, orange, or yellow, or double flowered, then you probably have a TROPICAL hibiscus. Hardy hibiscus do not come in these colors or in doubles! Many tropical hibiscus flowers have more than one color in a bloom either in bands or as spots.

Also Know, are all types of hibiscus edible? The edible parts of a hibiscus plant are the flowers, leaves, and fruit aka “calyxes.” Some people say that all hibiscus plants are edible, although given the number of varieties (including new hybrid varieties) that abound, that's a riskier claim than we're willing to make.

Accordingly, how many hibiscus colors are there?

More than 200 species of hibiscus come in a variety of colors, including pink, orange and yellow.

What kind of hibiscus is a perennial?

Tropical hibiscus plants are either brought indoors during cold weather or are treated as annuals, because of their sensitivity to the cold. Perennial hibiscus (Hibiscus spp.) are known to be cold hardy, but will still die down to the ground in all but the warmest U.S. Department of Agriculture plant hardiness zones.
