Rose of Sharon, Hibiscus syriacus, is a late flowering, hardy hibiscus, which brings life and colour to the garden when other plants are past their best. It bears large, trumpet-shaped flowers in pink, white or purple, from late summer to mid-autumn, against a backdrop of dark green, three-lobed leaves.


The name rose of Sharon has a symbolic meaning – in the Bible, the Rose of Sharon represents beauty, and is used to describe the beauty of King Solomon's lover in the book of Song of Solomon. Nowadays, rose of Sharon symbolises love, beauty and healing to Jews and Christians. Some see rose of Sharon as a symbol for Christ.

Also known as the Korean rose and tree hollyhock, rose of Sharon is the national flower of South Korea and appears on several national emblems, as well as their banknotes.

Rose of Sharon relates to only one type of hibiscus. There are several types of hibiscus, including tropical Hibiscus rosa-sinensis, which is typically grown as a house plant. Only Hibiscus syriacus is known as rose of Sharon.

Rose of Sharon can grow to a height and spread of 2m x 2m.
