I've always been a big fan of this plant (schlumbergera truncata or "Thanksgiving Cactus" or "Christmas Cactus" or, I guess in this case... the "Leap Day Cactus"). We have several and they generally do bloom around Thanksgiving or Christmas, but this one is either really happy or really sad because it's been blooming off and on since the holidays.
I'll go ahead and predict now that a good percentage of my 366-project photos will end up featuring plants. You've been warned.
Agave parryi, known as Parry's agave or mescal agave, is a flowering plant in the family Asparagaceae. It is a slow-growing succulent perennial native to Arizona, New Mexico, and northern Mexico.
The leaves are grey green and have a spine at the tip. One of the distinguishing features is that the point on the tip, which is typically dark tan, brown, or black, is darker than the leaf. Indentations of previous leaves show on the back of each leaf. The Huachuca variety grows in a rosette pattern as large as 2½ feet in diameter.
Native, warm-season annual or short-lived perennial, erect, hairless, tufted C4 grass usually less than 50 cm tall and forming a dense low crown; sometimes short stolons are present. Stems are unbranched and flattened with a knee-like bend near their base. Flowerheads are digitate, usually with 6-9 branches 4-20 cm long. Mostly found along roadsides and in native pastures where groundcover and fertility are relatively low; rarely abundant. Readily colonises bare ground and areas subject to compaction or shallow soils. Native biodiversity. Of little significance for grazing, it has low to moderate quality and low productivity. Tolerant of set stocking and close grazing, it is better suited to sheep than cattle due to the low height of its foliage. Favoured by grazing systems that maintain low groundcover. It has little response to fertiliser inputs.

The plant in the image is a Christmas cactus, also known as a Thanksgiving cactus or Christmas flower (scientific name: Schlumbergera truncata).
One of the flowers on my Christmas cactus in full glory. Look pretty big this year.Schlumbergera is a small genus of cacti with six species found in the coastal mountains of south-eastern Brazil. Plants grow on trees or rocks in habitats which are generally shady with high humidity and can be quite different in appearance from their desert-dwelling cousins. Most species of Schlumbergera have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. In Brazil, the genus is referred to as Flor de Maio (May flower), reflecting the period in which they flower in the Southern Hemisphere.
This genus contains the popular house plants known by a variety of names including Christmas Cactus, Thanksgiving Cactus, Crab Cactus and Holiday Cactus, which are Schlumbergera cultivars, and flower in white, pink, yellow, orange, red or purple. (The Easter Cactus or Whitsun Cactus, which may also be called a Holiday Cactus and has vivid scarlet flowers in the most commonly grown form, is now placed in the genus Hatiora.) The cultivars of Schlumbergera fall into two main groups:
The Truncata Group contains all cultivars with features derived mainly from the species S. truncata: stem segments with pointed teeth; flowers held more or less horizontally, usually above the horizontal, whose upper side is differently shaped from the lower side (zygomorphic); and pollen which is yellow. They generally flower earlier than members of the Buckleyi Group and although common names are not applied consistently may be distinguished as Thanksgiving Cactus, Crab Cactus or Claw Cactus.
The Buckleyi Group contains all cultivars with at least some features clearly showing inheritance from S. russelliana: stem segments with rounded, more symmetical teeth; more or less symmetrical (regular) flowers which hang down, below the horizontal; and pollen which is pink. They generally flower later than members of the Truncata Group and are more likely to be called Christmas Cactus.

This plant was a gift from JRA (2016-03), as (synonym) Haworthia ikra. Collected in Bolo Nature Reserve, RSA. Plant ID: ISI 1762. Now dead.
In World Ckecklist of Selected Plant Families (Kew), Haworthia ikra Breuer, Gen. Haworthia 1: 7 (2010) is considered a synonym of Haworthia cooperi var. truncata (H.Jacobsen) M.B.Bayer, Haworthia Revisited: 55 (1999).
(Brazoria truncata var. pulcherrima). East-Central Texas.
Brazoria truncata var. pulcherrima is a rare mint endemic to xeric sandylands of a handful of counties in East-Central Texas.
Brazoria truncata var. pulcherrima was one of my 2017 biodiversity goals. To read more about these goals and my pursuit of this species check out my blog by clicking here.
