Variety traits

Zantedeschia tuber

Zantedeschia Spreng.

Zantedeschia does not form bulbs in the botanical sense; its underground storage organ is a tuber or a rhizomatous tuber.

In the reference 8 varieties crop Arum-lily, where this is mentioned in the description.

The underground organ of Zantedeschia is a tuber possessing a distinct growth point and a basal plate from which adventitious roots develop. When assessing the quality of planting material, tissue integrity, the absence of rot, and the state of dormancy characteristic of deciduous species are of critical importance.

The agronomy of the crop requires strict adherence to a dry dormancy period for the tuber, as excessive moisture during this time leads to tissue decay. Unlike true bulbous plants, Zantedeschia is not subject to standardized circumference measurement scales regulated by variety testing protocols.

During cultivation, it is necessary to consider the morphological differences between tuberous species and forms with robust rhizomes, such as Zantedeschia aethiopica. Planting of the tubers should be carried out with the growth point facing upward, and when propagating, one should account for the organ's tendency to form offsets that develop into dense clusters.
