'Cheyenne'^™ Mock Orange (Philadelphus lewisii 'Cheyenne') has fragrant flowers that bloom for a couple weeks in early summer. It's arching branches are reminiscent of the Bridal Wreath Spirea whose flowers fade just as the Mock Orange comes into bloom. This specimen is between 7 and 8 feet tall.

Pruning should be done after blooming as it blooms on the current years growth. Rejuvenation pruning should be started as this shrub ages to remove any old or damaged canes. Remove them as close to the ground as possible. Gangly stems can be removed or cut back to shape the plant if necessary.

'Cheyenne'^™ is a 2001 Plant Select introduction. The parent was located "at the USDA Field Station at Cheyenne, Wyoming, where it formed a spectacular and carefree specimen. It has thrived over many decades there with no care. Intensely fragrant, nearly two-inch, white blooms." - http://www.plantselect.org/plant_list.php?sort=botanic.
