Establishment
First yearYoung shrub focuses on root development and establishing multiple stems from base
Keep soil consistently moist; avoid heavy pruning first year; mulch to retain moisture and regulate soil temperature
Vegetative Growth
Year 2-3Plant develops dense, multi-stemmed structure with medium green foliage; stems gradually show color development
Prune in early spring to remove damaged wood and encourage branching; thin overcrowded stems; maintain regular watering schedule
Flowering
May-June (4-6 weeks)Small, creamy-white flowers appear in flat clusters (cymes) along stems in late spring
Flowers appear on previous year's growth, so avoid heavy pruning after flowering; provide consistent moisture
Fruiting
July-SeptemberFlowers develop into small, round blue-white to pale blue berries that persist into early fall
Berries attract birds; provide wildlife habitat by allowing some berries to remain; maintain moisture for fruit development
Winter Color
November-MarchLeaves drop in fall (often turning reddish-purple); bare red to crimson stems provide striking winter ornament
Prune in late winter (February-March) to remove old, dull stems and encourage bright new growth; stem color is brightest on 1-3 year old wood

Harvest Tips
Not harvested like a crop; prune in late winter (late February to March) to remove 1/3 of oldest stems at base to rejuvenate and encourage bright red new growth. Cut above a healthy bud. For maximum winter color, prune more severely every 2-3 years. Branches can be cut for winter arrangements.
Fun Facts
- 🌱 The name 'Cornus' comes from the Latin word for horn, referring to the hard wood, which was historically used to make arrows, spear shafts, and tool handles.
- 🌱 Cornus alba can be coppiced (cut back hard) every 1-2 years to maintain a dense, compact form and encourage the brightest red stem color, as new growth is more vibrantly colored than mature wood.
- 🌱 This species is extremely cold-hardy and was one of the first ornamental shrubs cultivated in northern Europe and Russia, making it a legacy plant in Victorian gardens.
