Variety description

10 August 2026

The variety belongs to tall Aglaonemas; mature specimens are capable of reaching a height of 1.2–1.3 meters. The plant is characterized by a slow growth rate and forms robust light-cream stems that can become woody with age.

Leaf blades have an elliptical shape with pointed tips and a dense, leathery, shiny surface. The leaf color is dark green, complemented by a light white-yellow or white pattern in the form of veins and streaks.

The plant is thermophilic and sensitive to drafts or temperature fluctuations. The variety is demanding regarding the irrigation regime, as excessive soil moisture triggers the development of root rot. The plant sap is toxic.
