Variety traits

Peduncle — Pelargonium peltatum

Pelargonium peltatum (L.) L'Hér.

The peduncle is a key varietal trait of Pelargonium peltatum, determining the plant's cascading architecture. Its length is measured from the point of attachment to the stem to the calyx and ranges from 12–18 cm.

In the reference 9 varieties crop Ivy-leaf geranium, where this is mentioned in the description.

During variety testing, peduncle length is classified according to the UPOV scoring scale into short, medium, and long specimens. This length parameter directly affects the ornamental value of the species: optimal dimensions allow the umbel inflorescences to be positioned above the foliage, while excessively short peduncles are visually lost within the vegetative mass.

The development of Pelargonium peltatum peduncles depends on environmental conditions, with excess nitrogen in fertilization potentially inhibiting their formation. Growth intensity and peduncle length are also significantly influenced by light levels, which trigger elongation under deficiency, as well as diurnal temperature fluctuations.
