Purple Pillar Rose of SharonPurple Pillar,' along with its sister 'White Pillar,' are unlike any other Rose of Sharon we've seen! Their distinctly upright growth habit forms a column of beauty that can be used to flank an entrance or grouped to create a dramatic privacy screen. 'White Pillar' produces gorgeous large, showy DOUBLE PURPLE flowers. Plants leaf out very late in the Spring sometimes not until early May in our area.
