Description: Faucaria lupinaSN|16572]]SN|16587]] is a local or morphological form of the very variable Faucaria felinaSN|16587]]SN|16572]]. It is a very ferocious-looking plant known as 'Wolfs Jaws' for the resemblance of the top pair of leaves to the gaping jaws of an animal. Although the variation in F. felina is great, as is reflected by the numerous synonyms, the F. lupina can be identifed by the silvery green, long, triangular leaves, with fierce-looking teeth along the upper margin. The flowers are yellow and open only in full sunlight in late fall to winter.
Habit: It is a compact, little branched, groundcover, perennial succulents.
Stem Very reduced, tufted and developing a very short branched rhizomatous trunk with age.
Leaves: Up to 70 mm long, 5-20 mm broad, slender, spreading, rhomboidal, somewhat elongated, tapering gradually, keeled and triangular in cross-section. Margins with 5-8 teeth in the upper half (rarely more or less); teeth broad, fleshy, curved, white or pink ending in papillate awns of 0,5 to 3 mm length. Faces of leaves dark green to grey-green smooth or with indistinct whitish-grey dots, wax cover thin, crystals in the outer walls in certain areas resulting in white dots.
Flowers: Daisy-like 3,5 cm in diameter with yellow petals.
Blooming season: Late autumn to winter.
Fruit: Base broadly bell-shaped, top with the valves often raised in the centre, 10-16 mm long, 9-11 mm in dameter.
Seeds: 1,4-1,5 mm broad.

Cultivation and Propagation: Faucarias are the good choice for anyone wanting to start growing succulents. They are quite hardy and can take a short period of light frost and in very dry warm regions these succulents make very impressive out door ground covers. As house plants they tend to grow in fair weather and rest when temperatures are too hot or too cool.
Exposition: They need full sun to light shade , it should be protected from too much exposure in Summer. They do not do well in full shade as they tend to etiolate, fall over and rot easily.
Soil: It likes a well-drained soil mix, but can tolerate a wide variety of soil types and growing locations as long as there is plenty of sun.
Fertilization: The plants are fertilized only once during the growing season with a balanced fertilizer diluted to ½ the recommended strength.
Watering: This species is native to a primarily summer rainfall area but in cultivation the plant can be watered year-round. The plants are well watered during the growing season and allowed to dry thoroughly before watering again and will tolerate some over watering, but the challenge is to help them keep their compact form and prevent elongation of the stem. During the winter months, the plants should be kept quite dry, only watering enough to keep the leaves from shrivelling.
Pest & diseases: Faucarias are sensitive to mealybugs.
Rot: Rot is only a minor problem with Faucaria if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much. Care must be given in watering, keeping them warm and wet while growing, and cooler and dry when dormant.
Hardiness: Although the plants will survive mild frost if kept dry (hardy as low as -5° C) they should be protected from frost to prevent scarring. USDA 9b-12
Propagation: Faucaria is very easy to start from seed. Seeds germinate in 7-14 days at 21°C. Although they will start from cuttings, it is quite difficult to get them to root. If they start to rot there is usually part of the plant that can be removed and possibly rooted.
