Plant height — Pelargonium grandiflorum

Pelargonium grandiflorum (Andrews) Willd.

Plant height is a key morphological trait of Pelargonium grandiflorum, used in DUS testing and breeding to evaluate the compactness of cultivars.

In the reference 11 varieties crop Regal pelargonium, where this is mentioned in the description.

For Pelargonium grandiflorum, the height parameter is measured in centimeters from the soil level to the top of the plant or the point of attachment of the inflorescence. According to the standards for testing distinctness, uniformity, and stability, the average height of cultivars typically ranges from 30 to 50 cm, whereas wild forms can exceed 75 cm.

Plant height directly affects production parameters, including the planting density of seedlings, which for commercial varieties is between 10 and 18 plants per square meter. Insufficient light levels and disruptions in the temperature regime cause shoot elongation, which reduces the market quality of the crop and requires the use of plant growth regulators to form a compact habitus.
