(Butterfly Bush) Prolific and fragrant bloomer that will attract butterflies and hummingbirds!  English Butterfly™ Purple Emperor™ is extra bushy and loaded with clear bright-purple flowers.  It has extremely tight flower heads that are approximately 5 to 6 inches in length.  The foliage is narrower, almost strap like.  Purple Emperor™ Butterfly Bush is a Shrub Source favorite! This is a great flowering and neatly growing shrub that is a must for your landscape or perennial garden. Deer resistant! The English Butterfly™ series are colorful Buddleia varieties that won't crowd their neighbors! These cultivars were developed in England, and are just now making their way across the Atlantic. Roughly a third the size of other butterfly bush varieties, these plants are extra bushy and loaded with colorful flowers. They're fragrant, and attract butterflies and hummingbirds. Unlike older varieties, these cultivars will not overwhelm the landscape, and never develop the weedy, unkempt habit so typical of Butterfly Bush. You'll love the way they look in containers and in gardens. Treat them like a perennial in the north; dies back to the ground (roots are hardy).
