Description: Gasteria carinataSN|1476]]SN|17224]] is a small to medium-sized decumbent to erect aloe-like succulent. It offsetts freely from the base and soon forms a dense cluster with dull green speckled leaves and racemes of pinkish flowers during spring. Dimension of the clumps 3 to 18 cm tall and 15 to 80 cm wide. It is an extremely variable species. Nowhere in the genus Gasteria is variability illustrated more clearly than in this species. The different clones vary in leaf size, shape, marking, texture, growth habit and some forms have undulating leaves.
Variegated form: The variegated form (Gasteria carinataSN|17224]]SN|17224]] f. variegata) distinguish from the type species for the dark-green leaves variously stripped with yellow or cream. In cultivation there are several variegated clones all named Gasteria carinataSN|17224]]SN|17224]] f. variegata with leaves of different shapes and sizes (usually smaller) and with different degrees of variegation.
Roots: Succulent, up to 6 mm in diameter.
Rosettes: Distichous in a basal fan at first, becoming rosulate and decidedly twisted with 4-8 (or more) leaves, erect or spreading. Sometimes remaining distichous even in adulthood.
Leaves: 3-15 cm long, 1-5 cm wide at the base, fleshy, triangular-lanceolate, rarely tongue-shaped, narrowed to a stiff hard point, rarely obtuse, rounded , truncate, retuse, or mucronate. Sheets plane or concave above, with a distinct keel or sometimes rounded below, both faces dull green, tuberculate or smooth, rarely like sandpaper, spotted with raised or white domed tubercles scattered or coalescent into transverse rows. Margin cartilaginous, leathery, bearing small inconspicuous rounded teeth, rarely denticulate. Juvenile leaves distichous erectl or spreading, tuberculate or smooth, tongue-shaped (lorate), the tip rounded or ending in a hard sharp point (mucronate).
Inflorescence: Raceme, 15-90 cm, unbranched or occasionally with a pair of side branches. The floral bracts 6–12 mm long, 2,4 mm broad at the base.
Flowers 2,5-4 cm long like the usual of this genus, pedicel 7–15 mm long, perianth 16-27 mm long, gasteriform part pink swollen at the base by more than half of the flower length, narrowly ellipsoid to rarely globose-ellipsoid, above constricted into a tube 3-5 mm in diameter. Segments tips light pink to white with central green stripes: Stamens oblong, included. Ovary 6-7 mm long, 2,5 mm in diameter. Style 14 mm.
Blooming season: Winter to late Spring (July to November in the southern hemisphere) but with a peak in spring.
Fruit capsules: 19-23 mm long and 7 mm broad.
Seed: Oblong, 3-4 mm in broad, 2 mm thick.
Remarks: Gasteria carinataSN|17224]]SN|17224]] is related to Gasteria nitidaSN|17224]]SN|1476]] which has bright orange-pink flowers blooming during summer.

The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More...
Cultivation and Propagation: It is of easy culture and can grow on window sills, verandas and in miniature succulent gardens where it is happy to share its habitat with other smaller succulent plants, or in outdoor rockeries.
Growth rate: It is a relatively slow-growing plant that offsets to form in age small clusters..
Soil: It is tolerant of a wide range of soils and habitats, but prefers a very porous potting mix to increase drainage. A non-acid soil is ideal. You can grow a plant in a 10-15 cm pot for years and have perfectly happy plants. For best results, use a shallow pot.
Exposure: Need light shade to shade, but will take full sun part of the day. (with some sun exposure the leaf develops a nice reddish tint and remain compact) During the hot summer months, the soil should be kept moist but not overly wet.
Watering: During the hot summer months, the soil should be kept moist but not overly wet. During the winter months, water only when the soil becomes completely dry. Wet soil quickly causes root and stem rot, especially during chilly winter months. No water should ever be allowed to stand around the roots. Low ambient humidity is always needed.
Feeding: The plants are fertilized only once during the growing season with a balanced fertilizer diluted to ½ the recommended strength.
Hardiness: During the winter months, water only when the soil becomes completely dry. Frost hardy to -1°C (Or less).
Pest and diseases: Rot is only a minor problem with Gasteria if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much. Incorrect watering, poor drainage or too much shade can lead to attack by pests and diseases. Care must be given in watering, keeping them warm and wet while growing, and cooler and dry when dormant.
Remarks: Gasterias are best planted in a shaded and airy part of the greenhouse, and not too close to the glass roof or sides of the house as the plants can overheat during hot spells.
Propagation: Gasterias are easily propagated by the removal of offshoots or by leaf cuttings in spring or summer. To propagate by leaf cuttings, remove a leaf and let it lie for about one month, giving the wound time to heal. Then lay the leaf on its side with the basal part buried in the soil. This leaf should root within a month or two, and small plants will form at the leaf base. They can also grown from seed.
