Variety description

10 August 2026

The plant reaches a height of 120–180 cm and is capable of supporting large leaves, reaching 45 cm in length and 25 cm in width, without additional support. The center of the leaf has an emerald-green color, complemented by contrasting streaks and spots along the midrib and edges.

The variety possesses high growth vigor and physiological resistance. Research shows that this plant is able to maintain leaf turgor longer under drought conditions and recover faster after pruning compared to a number of other Dieffenbachia varieties.

The plant is intended exclusively for interior landscaping. Like all representatives of the genus, the variety contains calcium oxalate crystals, which makes it toxic upon contact with mucous membranes and requires caution when handling.
