Verbena trailing habit

Within the variety diversity of Verbena hybrida, trailing forms are classified as cascading or creeping, possessing flexible shoots 45–60 cm in length capable of hanging from containers or forming a ground cover. Genetically, this growth type is determined by the nature of internodes and the geotropism of the stems, which distinguishes them from upright or spreading bush forms.

When assessing the trailing habit, it is important to distinguish between genetic predisposition and physiological shoot elongation due to improper cultivation practices. Trailing varieties are characterized by a high demand for specific pinching to stimulate branching from the base, whereas upright varieties are prone to lodging when nitrogen is excessive, which is mistakenly interpreted as a trailing habit and creates a risk of powdery mildew infection.
