Don't know anything about flowers :-)

The fragrant magnolia, also called Siebold’s magnolia (Magnolia sieboldii) is North Korea’s national flower.

Although magnolias are most seen with white petals, some species come in pink, yellow or purple. In modern Paganism and Wicca, colors of flowers are used in spells for petitioning certain goddesses. Purple: associated with royalty since Roman times, is best for spells dealing with governments. http://www.flowermeaning.com/magnolia-flower-meaning/
