Haworthia truncata var. truncata

CACTUS ART
Cultivation and Mail Sale
of Cacti and Succulents.


This desirable species, despite the fact that actually is common in cultivation, still inspires trepidation and admiration by way of its unusual truncate leaf tips. It is a superb succulent, unique, distinctive and very different for any collection

Etymology:
The
genus "Haworthia" is named after the British botanist Adrian Hardy Haworth (1767–1833)
The specific name "truncata"derives from the Latin adjective “truncatus” meaning “cut off, truncated” (The specific name implies:
"squarely cut off")
 

Description:  This desirable species, despite the fact that actually is common in cultivation, still inspires trepidation and admiration by way of its unusual truncate leaf tips. It is a superb plant, unique, distinctive and very different for any collection
Habit: Stemless distichous  plants, medium sized  with windowed leaves on upper margin. Solitary or slowly clumping depending on the clone (Unpredictably, some plants remain unbranched, while others readily cluster)

Leaves: The leaves look as if they have been roughly cut off at the tops and they are arranged like a fan, not a rosette. As the plant grows take on an almost crested appearance. The leaf size and thickness, of the end-areas will vary greatly from clone to clone. The surface is warty and the blunt end is transparent whit some interesting leaf markings, others are rather plain, this "lightning flash" patterns in the leaves do not come out until the plant reaches maturity.


Fenestrate leaves:
This plant is a choice example of the window-leaf ( fenestrate leaf) adaptation found in many Haworthias, Mesembreanthemums and Peperomias, the translucent 'glassy' windowed apices allow light into the internal plant body rich in chlorophyll-bearing layers of cells, thereby providing a much larger assimilation area.
The windows greatly increase the photosynthesizing area by allowing light into the centres of leaves and at the same time avoiding water loss
.


Notes:
This species has been the subject of passionate work of breeding and selection by the Japanese, and a number of wonderful cultivars with white lacy patterns on green-grey windowed tips have been developed and propagated, and some specimens have a very unique leaf shape.

Cultivation:  Not difficult to cultivate, though it is not fast growing and takes several years to form good looking heads,  Must be repotted frequently, because every year a part of their roots die and then rots in the pot.
Watering Needs: Water regularly in the growing season, they should never dry out completely during the rest period
Frost Tolerance: 
Hardy to -1 (-5)°C
Propagation:
Seeds, offsets. 
Sun Exposure: it prefer locations where it's bright or in  light shade, it can tolerate shade, shelter from direct sun during the hottest hours.

Family: Asphodelaceae (Aloacee - Liliaceae)

Scientific name:  Haworthia truncata var. truncata Schoenland
Published in: Václav Richtr, p. 108

Distribution: South Africa (Western Cape: Little Karoo) in Oudtshoorn area (in a number of locality, Volmoed, Vanwykskraal, Dysselsdorp etc.)

Habitat: They grow in the shade of bushes and occasionally in open areas. They grow underground with only the apex of the leaves rising above the soil surface so that they are difficult to find. This is an excellent protection against herbivores . This very singular plant has contractile leaves that will pull the plant into the ground during times of drought, leaving only the windowed tops exposed.
