Variety description

10 August 2026

The variety is a bushy herbaceous perennial. Large lanceolate leaves reach 30–40 cm in length and are distinguished by a characteristic coloration: wide creamy-white or light lime-green centers transition into a deep green margin, often complemented by small green spots or streaks.

The plant has a moderate growth rate, adding 15–25 cm in height per season. The variety is demanding regarding the watering regime and air humidity level, as the thin leaves are prone to marginal burns under unfavorable conditions, and the root system is sensitive to water stagnation.

The plant is toxic due to the content of calcium oxalate crystals in the sap. When working with it, including pruning and repotting, protective gloves must be used.
