• Flowering bushes grow throughout Pennsylvania's landscape. Several species of flowering bushes are native to the Keystone State, growing wild but more than suitable for landscaping needs. Some have showy flowers that are their main asset, while others have appeal throughout the year.
  
  

Rosebay

• Rosebay (Rhododendron maximum) is a flowering bush found in Pennsylvania with a range across the state into the Southwest corner. Rosebay grows between 8 and 15 feet tall. The plant has multiple stems and is an evergreen variety with multiple cultivars. The flowers emerge in late June, which the University of Connecticut Plant Database notes is later in the year than many Rhododendron species. Rosebay's flowers are rose, pink, white or combinations of these colors. The flowers grow in clusters of as many as 25. Rosebay prefers shade, cool damp soil and is useful as a screen or in a shrub border.
  
  

American Elder

• The American Elder (Sambucus canadensis) works best in wet areas next to roadsides and in naturalized gardens. The flowering bush grows as high as 15 feet. The small, white flowers, developing in flattened groupings capable of covering the entire bush, emerge in spring, according to the Floridata website.
  
  The American Elder turns out clusters of edible berries appealing to birds and other wildlife. A major drawback of this flowering bush is that it reproduces by sending up shoots from its roots. This causes dense thickets to take shape if not continually pruned. The bush thrives across all of Pennsylvania.
  
  

New Jersey Tea

• New Jersey Tea (Ceanothus americanus) is a small, flowering Pennsylvania bush, growing to 3 or 4 feet. The plant ranges from Southern Canada into the Eastern, Southeastern and Central regions of the United States, with a distribution across Pennsylvania. New Jersey Tea's small size makes it suitable as a groundcover in rocky spots, notes the Missouri Botanical Garden. New Jersey Tea's aromatic white flowers bloom from May to July, luring butterflies and hummingbirds with its sweet nectar.
  
  

Ninebark

• The bark of Ninebark (Physocarpus opulifolius) is an attractive feature in the winter months. Its exfoliating nature reveals inner bark layers of reds and browns. The leaves hide this from view in spring and summer, but the flowers of late spring snap the Ninebark into the limelight. The white or pink flowers become clusters of red fruits. Ninebark's possibilities include usage as a screen, as a shrub border, as a hedge or erosion deterrent. Ninebark grows 5 to 8 feet high and Pennsylvania is well within its geographic distribution.
