What Are Japanese Lilacs?
Japanese lilies are native to Japan and Asia. They have been cultivated since ancient times. These plants produce small flowers which bloom only once every few years. The flower petals are usually red, but they can be any color.
There are only two different types of lilies that are native to the region: the common lira and the smaller red lily. The red lily is the most popular for a number of reasons:
It has a pleasant smell. It’s more resistant to pests than other types of lilies. It blooms more readily than other types of lilies.
The red lily’s scientific name is Lilium aurantium var. quadrivalutn.
