Cotyledon tomentosa Harv.
Fl. Cap. (Harvey) 2: 373. 1862 [15-31 Oct 1862]
Family: CRASSULACEAE
Cultivo y propagación: Cotyledon tomentosa es una planta que se vende con relativa frecuencia en los viveros de jardinería, y puede hacer un buen chicle bajo y suculento en el jardín, se adapta bien en contenedores y es una buena planta de interior. Se cultiva ampliamente y no es difícil de cultivar. Los cotiledones son muy sensibles a las diferentes condiciones culturales, tanto en lo que respecta al color, la longitud y la forma de las hojas, la tasa de crecimiento y el tamaño de la planta. Están inactivos en verano y prosperan con luz brillante y abundante flujo de aire.
Tasa de crecimiento: Moderadamente rápido.
Suelo: crece mejor en suelo arenoso y arenoso. Un buen drenaje es muy importante ya que es propenso a la pudrición de la raíz.
Fertilización: aliméntelo una o dos veces durante la temporada de crecimiento con un fertilizante específicamente formulado para cactus y suculentas (pobres en nitrógeno), incluidos todos los micronutrientes y oligoelementos diluidos a la mitad de la concentración recomendada en la etiqueta.
Necesidades de riego: es una planta tolerante a la sequedad. Riegue regularmente en la temporada de crecimiento, pero evite el agua y deje secar entre riegos. Riegue con precaución en invierno, ya que la planta puede perder sus raíces si el suelo se mantiene frío y húmedo durante períodos prolongados. Si se cultiva en un recipiente, se recomienda regar el fondo sumergiendo el recipiente. Debe tener una atmósfera muy seca.
Exposición al sol: lo hace bien a pleno sol, pero también puede manejar un poco de sombra. A la sombra, el color de las hojas se mantendrá más verde, mientras que en las duras condiciones de pleno sol el follaje puede desarrollar un tinte amarillento pálido. En verano, manténgase fresco y proteja del sol directo durante las horas más calurosas. Puede quemarse con el sol si se mueve de sombra / invernadero a pleno sol demasiado rápido. Tiende a ser realmente leggy en la sombra profunda).
Tolerancia a las heladas: proteger de las heladas para evitar las cicatrices. Requiere una temperatura mínima de aproximadamente 5 ° C, pero tendrá una helada ligera y es resistente a -5 ° C por períodos cortos si está en suelo seco (temperatura letal en hábitat -6 a -10 ° C). Zonas USDA 9A - 11. En áreas propensas a las heladas, crezca en un invernadero intermedio o invernadero, en macetas.
Usos: hacen maravillosas plantas balanceadoras en áreas calientes y secas y también se cultivan bien en contenedores o patios soleados o en un rincón caliente al lado de una piscina.
Advertencia: Las plantas son altamente venenosas para los seres humanos y los animales domésticos, especialmente las ovejas y las cabras, y la carne de los animales sacrificados por cotiledonesis sigue siendo tóxica incluso después de la cocción. El envenenamiento puede ser agudo o crónico, este último debido al efecto acumulativo de la toxina.
Plagas y enfermedades: Puede ser susceptible a las cochinillas y rara vez escalar. Proteger del frío
Propagación: de la semilla, pero se aumenta fácilmente mediante esquejes. Los esquejes se arraigan fácilmente. También es posible plantar las hojas en un suelo bueno y arenoso donde echarán raíces: los miembros de esta familia a menudo se propagan vegetativamente de esta manera.
Origin and Habitat: Cape Province (Ladismith area between Groot River and Trumpeter's Poort), South Africa.
Habitat: It grow in rocky quartz fields and on steep, shady quartzitic sandstone cliffs where they have excellent drainage provided by very porous soil.

ENGLISH: Bear's Paw, Kitten Paws, Woolly Cotyledon
PERSIAN (فارسی): پنجه خرس
RUSSIAN (Русский): Котиледон томентоза
Description: Cotyledon tomentosa (Bear's Paw or Kitten Paw), is a succulent shrublet native to Africa that can rich a height of 30-70 centimetres and a diameter of 30-50 cm, more or less densely branched. Like all tomentose plants this has leaves, flowers and stems all covered with down. The leaves, grape- to thumb-sized, feel fat and soft to the touch just like the little paddy paws of a baby animal, complete with red toe-nails It forms large orange bell-shaped flowers in spring.
Stems: Thin, 3-4 mm in diameter, set loosely 10-15 (or more) cm. long, tomentose to pilose, branching profusely near ground level.
Leaves: Plump, soft, ± opposite, decussate, and densely clothed with woolly hairs, obovate oblong, oblanceolate to oblong-elliptic, cuneate, 1.5-5.5 cm long and 8-15 cm broad, convex, tapered to a short stalk at the base, apex scalloped with prominent dark red "teeth" at tips. These teeth are arranged in a neat row and vary in number between three and ten. There are bright green or yellow-green leaf forms with yellowish hairs, as well as grey ones with whitish hairs covering the leaves.
Inflorescence: The inflorescence is a thyrse with 1-3 dichasia, with 10—20 nodding florets; peduncle 0,15-0,25 m long, densely hairy. Scape slender, covered with a dense felt of hairs, 10—20 cm. long.
Flowers: Red to almost yellow typical Cotyledon urn-shaped with five petals that separate near the tips to curl back at the mouth, usually pointing outwards on quite short pedicels . Sepals triangular, 3-5 mm long, bluntly acute, densely felted. Corolla tube vaguely ampullaceous to cylindrical, 12-16 mm with recurved-spreading lobes half as long, hairy outside, glabrous within except for tuft of hairs where filaments are fused to tube.
Stamens 10, anthers 1.5-1.8 mm long. Squamae transversely oblong, 0.5-1 x 1.3-1.6 mm, slightly emarginate, pale yellow.
Subspecies, varieties, forms and cultivars of plants belonging to the Cotyledon tomentosa group
Cotyledon tomentosa Harv.: has leaves, flowers and stems all covered with down. Leaves scalloped with 3 to 10 prominent dark red "teeth" at tips. Distribution: From Groot River to Trumpeter's Poort.
Cotyledon tomentosa subs. ladismithiensis (Poelln.) Toelken: has stronger branches to 1 m tall. Leaves oblong-elliptic with 1 to 3 (or more) sharp apical teeth and pendulous red flowers. Distribution: Ladismith and Laingsburg.
Cotyledon tomentosa subs. ladismithiensis f. variegata hort.: has creamy-yellow patches on foliage and few pointed teeth on leaves tips.
Cotyledon tomentosa f. variegata hort.: has cream patches on foliage, usually around edges and up to 10 red teeth in a line on leaves tips.
Cultivation and Propagation: Cotyledon tomentosa is a relatively commonly sold plant at garden outlet nurseries, and can make a nice low succulent shrublet in the garden, does well in containers, and makes a good houseplant. It is widely grown and not difficult to cultivate. Cotyledons are very responsive to differing cultural conditions both as regards colour, length and shape of leaves, rate of growth and size of plant. They are dormant in summer and thrive with bright light and ample airflow.
Growth rate: Moderately fast.
Soil: It grows best in sandy-gritty soil. Good drainage is very important as it is prone to root rot.
Fertilization: Feed it once or twice during the growing season with a fertilizer specifically formulated for cactus and succulents (poor in nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label.
Watering Needs: It is a very dry-tolerant plant. Water regularly in the growing season, but avoid water-logging and let dry between waterings. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended periods. If grown in a container, bottom watering by immersing the container is recommended. It must have very dry atmosphere.
Sun Exposure: Does well in full sun, but can handle some shade, too. In shade the leaves colour will remain more green, while in harsh full sun conditions the foliage can develop a pale yellowish tinge. In summer keep cool and provide some shelter from direct sun during the hottest hours. It can be sunburned if moved from shade/greenhouse into full sun too quickly. It tends to get really leggy in deep shade).
Frost Tolerance: Protect from frost to prevent scarring. It requires a minimum temperature of about 5°C, but will take a light frost and is hardy down to -5° C for short periods if it is in dry soil (Lethal temperature in habitat -6 to -10 ° Celsius). USDA zones 9A – 11. In areas prone to frost, grow in an intermediate greenhouse or conservatory, in pots.
Uses: They make wonderful rocker plants in hot, dry areas and also grow well in containers or sunny patios or in a hot corner next to a swimming pool.
Warning: The plants are highly poisonous to humans and domestic animals, especially sheep and goats, and the meat of animals killed by cotyledonosis remains toxic even after cooking. Poisoning may be acute or chronic, the latter due to the cumulative effect of the toxin.
Pests and diseases: May be susceptible to mealybugs and rarely scale. Protect from cold.
Propagation: From seed but it is easily increased by cuttings. Cuttings root easily. It is also possible, to plant the leaves in good, sandy soil where they will take root - members of this family often propagate vegetatively in this way.
