Move over, Empress, there is another Wu in town poised to steal the spotlight! 'Wu-La-La' has huge blue-green leaves (up to 24" long!) edged by a striking apple-green margin that turns yellow with some sun. The answer to all who have been wanting a more colourful alternative to the giant 'Empress Wu'. It is a strong grower with fertile, pale lavender flowers are held just above the foliage in mid-summer.
