Flowering Dogwood Growth

Overview

Flowering dogwoods (Cornus florida) are small, deciduous trees with a symmetrical form and a broad, rounded canopy of foliage. Flowering dogwoods grow to 40 feet tall and have simple, 6 inch, ovate-shaped, crinkled, light green leaves. Their flowers are small, dense clusters surrounded by white, showy, petal-like bracts. Some cultivars have pink to red bracts. Dogwoods flower profusely in spring before their leaves expand.

Landscape Uses

Flowering dogwood trees are suitable as specimens, as framing trees, near patios and as small shade trees. Its flowers provide spring color, and its leaves provide color in the fall. Its form softens lines in the landscape and its nature is well-suited to growth at the edge of wooded areas and incorporated into shrub borders.

Flowering dogwoods prefer full sun to partial shade and nutrient-rich, well-drained, acidic soils. Flowering dogwoods are slightly salt tolerant. Waterlogged conditions, pollution and compacted soil are all detrimental to optimum growth. It is especially important to adequately irrigate flowering dogwoods during their first year of planting, especially when established in a hot location. In fact, dogwoods planted in full sun locations benefit from regular irrigation during the lifetime of the tree. Those planted in shade need less irrigation unless it is a time of drought.
