Origin and Habitat: Juttadinteria deserticolaSN|11588]]SN|11588]] has a very wide, almost continuous, distribution along the coast from the Western Namaqualand (south of Alexanderbay), in South Africa to the District Lüderitz-South in Namibia. This species is known from 20 subpopulations with extent of occurrence estimated at 15,000–20,000 km².
Altitude range: It has been recorded at altitudes of 70 to 450 metres above sea level.
Habitat and ecology: Juttadinteria deserticolaSN|11588]]SN|11588]] grows in sand-blown plains between rocky outcrops, gentle slopes covered by gravel from quartz, dolomite, and lime-stone, rarely on phonolite (black) or sedimentary schists. The plant is perfectly adapted to live in the fog zone and draws most of its water from the fogs which roll in from the sea. The plants are associated with low succulent dwarf shrubby vegetation in association with Psilocaulin dinteri, Euphorbia verruculosa, Conophytum taylorianumSN|22686]]SN|17869]], Conophytum saxetanumSN|17869]]SN|22686]], Crassula aurusbergensis, Pelargonium cortusifolium, Bulbine rhopalophylla, Sarcocaulon multifidumSN|32359]]SN|32359]]}}, Tromotriche ruschiana, Hoodia officinalisSN|25797]]SN|25797]] subsp. delaetiana, Dracophilus dealbatusSN|11283]]SN|11283]] and Cephalophyllum ebracteatum plus several other. No threats are known at present and the population is believed to currently be stable.

Description: Juttadinteria deserticolaSN|11588]]SN|11588]] is a low growing succulent sub-shrub on woody roots, up to 20 cm tall. It has whitish, boat-shaped leaves and white flowers that appear in the growing season in autumn and winter.
Derivation of specific name: “deserticola” , from Latin “desertus”, deserted, desert; and Latin “-cola”, inhabiting; for the occurrence in very arid regions.
Stems: Decumbent, rarely ascending or erect, internodes rarely visible, in cultivation too.
Leaves: Pale green to whitish-grey, short, boat-shaped to pointed, length, stony up to 30(-40) mm long and less than 20 mm wide. Margins only in some northern populations with minute teeth. Northern and southern populations differ in their leaf shapes, the northern being more rounded apically, appearing broader, the southern more pointed, appearing slender.
Flowers: Large white in winter. Short stalked, daisy-like, 20-30 mm in diameter. Stamens 150-250, Petals 40-60.
Fruits (capsules): About 8-(or more)-loculed, 11-19 mm long, 6-10 mm broad, covering membranes absent or to 1 mm broad. Capsules are hygrochastic, a mechanism whereby seeds are dispersed by raindrops. When it rains, the keels of the wet seed capsules push open valves. Raindrops hitting the open seed capsule splatter seeds in different directions, thus ensuring recruitment and the subsequent survival of the species.

Soil: Requires good drainage as it it is prone to root rot.
Fertilization: they thrives in poor soils ans seems very sensitive to an excess of potassium.
Watering: Water minimally in summer, only when the plant starts shrivelling, water more abundantly when they are growing in the fall and spring. Requires little water otherwise its epidermis breaks (resulting in unsightly scars).
Light: Keep cool and shaded in summer, need full sun or light shade.
Hardiness: USDA zones 9A – 11. They prefer a very bright and arid situation and will take a light frost (Hardy to -5°C) if they are in dry soil.
Uses: Container, rock garden.
Propagation: Seeds, cuttings. It is difficult to root juttadinterias from cuttings and generally pointless as well, so quick are they from seed. They are easily propagated by seed.
