Giant Dogwood (Cornus controversa) - Description
C. controversa is native to Asia. It bears foliage with oval, 3 to 6 inch long leaves that are dark green above, silvery green beneath, and glow red in the fall. It produces creamy white spring flowers in fluffy 3 to 7 inch clusters. They also bear shiny blue-black fruit in the late summer which is enjoyed by birds.
Giant Dogwood (Cornus controversa) - Blooming
What appears to be flower petals borne on the branches of the Dogwood are actually colorful bracts that subtend the true and less conspicuous flower. Some bracts can be white or pink, but all offer fantastic "floral" displays in your garden. Followed by clusters of berriers.

Giant Dogwood (Cornus controversa) - Interesting facts
The leaves of Dogwoods are interesting for more reasons than just offering beautiful foliage to your garden. They have very strong, plastic-like vascular tissues that can be stretched without breaking. The tip of the leaf can be pulled away from the base of the leaf in the middle of the blade and will appear to "magically" float in the air. The tip of the leaf will be held to the base of the leaf by the plastic-like vascular bundles that are white in color and more difficult to see.
Giant Dogwood (Cornus controversa) - Soil and irrigation
