The plant in the images is a highly sought-after variegated specimen belonging to the compact "JBT" series, a prominent line of hybrid snake plants developed in Indonesia.

The prefix "JBT" stands for Juwono-Budi-Toni, representing a collaborative breeding initiative by a renowned trio of Indonesian horticulturists and Sansevieria experts: Juwono Wijaya, Budi Hidayat, and Toni Sunarto.

This specific hybrid line was bred primarily using the robust, thick-leaved species Sansevieria rorida (noted for its distinctive, stacked, fan-shaped growth habit) crossed with other hardy, compact species to produce unique architectural forms.

The "Silver" designation refers to the striking, luminous coloration of its foliage, which is characterized by thick, curving, canaliculate leaves that grow in a tight, distichous rosette.

This particular individual exhibits a spectacular, highly stable mutation featuring cream-to-yellow marginal variegation contrasting beautifully against the signature silvery-green and deep forest-green vertical banding.

True to its Sansevieria rorida lineage, the plant maintains a compact, heavy-textured profile with sharp, brownish-red terminal spines on the leaf tips and an incredibly vigorous, thick yellow root system.
