Azalea plant height

Rhododendron simsii Planch.

The height of an azalea (Rhododendron simsii) is a key morphological trait that determines the classification and commercial appearance of the potted crop. This parameter is measured in centimeters according to DUS testing guidelines and depends on varietal characteristics and the applied bush form…

In the reference 22 varieties crop Indica azalea, where this is mentioned in the description.

Indoor azalea varieties are characterized by compact forms with the height of commercial specimens ranging from 13–30 cm or 30–50 cm. Under natural conditions, the species can reach 1.5–2 m, while in potted culture, standard forms can reach a height of up to 1 m.

This trait directly influences ornamental properties, where preference is given to low, well-branched bushes with dense flowering. Height control is achieved through regular pinching of shoots and the use of growth regulators, which also requires adjusting planting containers and irrigation regimes.
