Petunias is a broad term that covers a wide variety of plant types. There are wave petunias, Supertunias, Crazytunias, and so many more types that fall under the petunia family.
Petunias are part of the nightshade family of plants and are native to Central America.
Over the years, many hybrids have come from the petunia family. One of the more popular hybrids was the wave petunia, which was a line developed in 1995.
With the hybrid varieties coming out came a wide variety of colors. Today, petunias can be found in almost all basic colors, such as white, black, red, yellow — as well as multicolored, and more unique color tones.
