Variety description

10 August 2026

The variety was bred as a result of crossing the parent forms Sweet Garden and Sweet Line. The plant has a trailing or semi-trailing growth habit and is well adapted to hot and humid conditions.

The appearance is distinguished by striking foliage with broad lobed blades, the base of which is heart-shaped or slightly sagittate. The variety is intended exclusively for ornamental purposes; the characteristics of the tubers as food products have not been evaluated.
