Salvia gesneriflora

Salvia gesneriflora (sometimes spelled Salvia gesneriiflora) is a herbaceous perennial plant or subshrub native to mountainous provinces of the Sierra Madre Oriental in Mexico, growing at 7,500–10,000 ft (2,300–3,000 m) elevation.

Hard annual pruning prevents the plant from breakage.

The plant has many woody stems and very heavy with foliage that break easily in wind and rain.

They grow abundantly in tightly spaced whorls on 8–12 in (20–30 cm) long inflorescences.

[1] In a 1970 collecting trip to Mexico by Huntington Botanical Gardens, two distinct varieties were collected — one with the more common green calyx, and one with a purple calyx and stem which was given the cultivar name 'Tequila'.
