"Stripped Snake plant" or "Striped Mother-in-law's Tongue") is a stemless perennial succulent herb forming dense stands, spreading by way of its creeping rhizome. Its sword-shaped succulent leaves grow upright from a basal rosette, and are rigid, deep green with horizontal bands of light greyish-green and bordered with a creamy yellow margin of variable width which is parallel with the veins of the leaf. It is one of the most commonly grown indoor and tropical garden ornamental plants. Flowers greenish white, to 1 cm long, clustered on a raceme to 75 cm long.
Rhizome: Sympodial, sometimes above ground, sometimes underground, robust, and yellowish 1.3 to 2.5 cm thick.
Leaves: 1–2(rarely to 6), vertical, very erect, linear-lanceolate and flat, tappering gradually from the middle or above, fibrous, fleshy, 45-to over 1 m tall, 5-7 cm wide, and channelled at the base, banded on both surfaces from base to apex, very distinct light dull green or clear whitish-green and deep grass-green to almost blackish-green, overspread with slight glaucous bloom, margins narrow, dull-green (var. trifasciata) or creamy-yellow (var. laurentii). The leaf surface is smooth.
Inflorescence (raceme): Erect (30–)40–75 cm high, loosely filled with three to eight flowers per bunch. Stalk 3–8 mm thick The bract is ovate or ovate-lanceolate, pointed, 3-12 mm long
Flowers:(1–)3–4 per cluster. Pedicels 50–85 mm long, upward-curved green with pale green dots. Flowers pale greenish or greenish-white, perianth is 1.9–2.3(-3)cm long, greenish-white, and scented. The sepals are linear and greenish. The stamens are 0.8 cm long and the style is 1.5 cm long.

It needs heat and dry air in Winter and half shade in Summer. Does best as a pot plant. Like all snake plants, it is very efficient in removing pollutants from indoor air.
Soil: Use a well-drained potting mix consisting of 3 parts loam to 1 part of pumice.
Fertilization: They are fertilized once during the growing season with a balanced fertilizer.
Repotting: Transplant only when plant is pot-bound.
Watering Needs: The plants are very drought tolerant and are watered about every other week during the growing season, allow to dry somewhat between waterings. During the winter months they are watered once a month.
Exposure: Bright filtered light. Will tolerate low light levels but grows best and flowers if given bright light and even tolerates full sun. Afternoon shade in summer.
Frost Tolerance: Avoid any frost. This species is dormant in winter, keep it at or around 4°C.
