Plant height — Impatiens walleriana

Impatiens walleriana Hook. f.

Plant height is a key varietal trait of Impatiens walleriana that determines its decorative use and planting density. The index ranges from 15 cm in compact forms to 70 cm in tall cultivars.

In the reference 32 varieties crop Busy Lizzie, where this is mentioned in the description.

For Impatiens walleriana, plant height serves as a basic criterion for distinctness, uniformity, and stability testing. Measurements are taken during the full development stage of the plants in centimeters, with cultivars classified on a scale of expression ranging from low to high.

The height range is determined by the breeding group: compact forms typically reach 15–30 cm, while medium and tall cultivars vary within the 35–70 cm range. This parameter directly determines the cultivation technology, including planting density, use in flower beds or containers, and the need for pinching to maintain the habit.

In cases of poor light or nutrient conditions, as well as excess moisture, the succulent stems of the impatiens are prone to excessive stretching. This leads to a loss of compactness and a decrease in decorative qualities, so height control is an essential element of crop management.
