The Story
Plant Bio
Cornus florida is a quintessential small flowering tree of eastern North American woodlands, celebrated for its graceful, horizontal branching and large, showy bracts in spring. It offers four-season interest with spring flowers, summer foliage, fall color, and winter structure. 'Cloud Nine' is a prolific bloomer, known for producing an abundance of large, overlapping, pure white bracts, even on young trees. It is also noted for being more cold-hardy than the species and having a slower, more compact growth habit.

Planting
How to Grow
- Choose a site with acidic, well-drained soil and afternoon shade.
- Dig a hole three times the width of the root ball.
- Set the tree so its root flare is slightly above soil level.
- Backfill with amended soil, creating a slight mound.
- Water deeply to settle the soil and remove air pockets.
- Apply a 3-inch layer of pine bark or leaf mold mulch.
Pro Tip
Plant in a location with morning sun and afternoon shade to reduce stress and risk of disease like anthracnose.
