The Story

Plant Bio

The Rutgers hybrid dogwoods are crosses between Cornus florida and Cornus kousa, developed to combine large flowers with high disease resistance and vigor. 'Rutdan', sold as CELESTIAL, is known for its extremely large, overlapping, pure white bracts. It is sterile, produces no fruit, and exhibits high resistance to dogwood anthracnose.

Bloom Period:

EarlyLate

Uses & Benefits:

Provides a spectacular late spring floral show with enormous, overlapping white bracts. The foliage turns an attractive reddish-purple in fall, and the layered branching provides winter structure.

As a sterile hybrid, it produces no fruit, making it a 'clean' tree for patios, poolsides, or walkways. Its disease resistance reduces the need for chemical sprays.

While it doesn't produce fruit for birds, its flowers still provide pollen for bees and other insects. Its dense canopy offers shelter for birds.

Planting

How to Grow

Select a site with well-drained, acidic soil and partial shade.
Dig a hole 2-3 times the width of the root ball, but no deeper.
Gently place the tree in the hole, ensuring the root flare is visible.
Backfill with the excavated soil, avoiding amendments.
Water thoroughly to eliminate air pockets.
Mulch with 2-3 inches of pine bark or compost, away from the trunk.

Pro Tip

Plant in a location with morning sun and afternoon shade to prolong the life of the flower bracts and reduce summer stress.
