Flower Chrismas Cactus Flowers

Type of Flowers 
Chrismas Cactus: 
Christmas Cactus "Schlumbergera" is a small-scale genus of cacti with vi species establish inwards the coastal mountains of south-eastern Brazil. Plants grow on trees or rocks inwards habitats which are mostly shady with high humidity together with tin hold out quite dissimilar inwards appearance from their desert-dwelling cousins. Most species of Schlumbergera convey stems which resemble leaf-like pads joined ane to the other together with flowers which look from areoles at the joints together with tips of the stems. Two species convey cylindrical stems to a greater extent than similar to other cacti. In Brazil, the genus is referred to equally Flor de Maio (May flower), reflecting the catamenia inwards which they blossom inwards the Southern Hemisphere.






This genus contains the pop solid plants known yesteryear a diverseness of names including Christmas Cactus, Thanksgiving Cactus, Crab Cactus together with Holiday Cactus, which are Schlumbergera cultivars, together with blossom inwards white, pink, yellow, orange, ruby-red or purple. (The Easter Cactus or Whitsun Cactus, which may likewise hold out called a Holiday Cactus together with has brilliant scarlet flowers inwards the around commonly grown form, is straightaway placed inwards the genus Hatiora.)






The cultivars of Christmas Cactus"Schlumbergera" autumn into ii psyche groups: 
-  The Truncata Group contains all cultivars with features derived mainly from the species S. truncata: stalk segments with pointed teeth; flowers held to a greater extent than or less horizontally, unremarkably higher upward the horizontal, whose upper side is differently shaped from the lower side (zygomorphic); together with pollen which is yellow. 
They mostly blossom before than members of the Buckleyi Group together with although mutual names are non applied consistently may hold out distinguished equally Thanksgiving Cactus, Crab Cactus or Claw Cactus.
- The Buckleyi Group contains all cultivars with at to the lowest degree simply about features clearly showing inheritance from S. russelliana: stalk segments with rounded, to a greater extent than symmetical teeth; to a greater extent than or less symmetrical (regular) flowers which hang down, below the horizontal; together with pollen which is pink. They mostly blossom after than members of the Truncata Group together with are to a greater extent than probable to hold out called Christmas Cactus.






Christmas Cactus "Schlumbergera" truncata was inwards tillage inwards Europe yesteryear 1818, together with S. russelliana was introduced inwards 1839. The ii species were deliberately crossed inwards England yesteryear W. Buckley resulting inwards the hybrid straightaway called S. × buckleyi, kickoff recorded inwards 1852. By the 1860s, a substantial number of cultivars (cultivated varieties) were available inwards a hit of colours together with habits, together with were used equally ornamental plants inwards "stoves" (heated greenhouses) together with inwards houses, where they were pop for their autumn together with wintertime flowering. Many cultivars were selected seedlings of S. truncata, but at to the lowest degree 3 S. × buckleyi hybrids were available, of which one, straightaway called S. 'Buckleyi', is idea to hold out the master copy Christmas Cactus. By the early on business office of the 20th century, the genus had drib dead less popular, together with many of the early on cultivars were lost.






From around the 1950s onwards, breeding resumed inwards Europe, North America, Commonwealth of Australia together with New Zealand. New plants were produced yesteryear crossing alongside the species together with existing cultivars of S. truncata, S. russelliana together with the hybrid S. × buckleyi. Treatments which induced mutations were likewise used. The number was a broad hit of blossom colours which had non been available before, including the kickoff truthful yellowish to hold out sold commercially, S. 'Gold Charm' (which was a sterile triploid). Breeders aimed for plants which grew strongly, were upright at the signal of sale rather than pendulous, had many flowers or buds, together with were adapted to living equally solid plants.In the 1980s the species S. orssichiana was likewise used inwards crosses. The hybrid of S. truncata together with S. orssichiana has been named S. × reginae or S. Reginae Group; ane of the kickoff cultivars was S. 'Bristol Queen'. S. opuntioides crosses convey likewise been made, but convey non resulted inwards commercially available cultivars.
