: Quiabentia pflanziiSN|19004]]SN|19007]] is a form of Quiabentia verticillataSN|19007]]SN|19004]], but not sufficiently differentiated and considered merely a local variant of the latter (if not the same). It is a large tree or shrubs, with fleshy, cylindrical stems and oval leaves rather straggly in habit, which may reach a height of 4 to 12 (-15) m tall in nature. Looks like a combination of a giant jade plant (Crassula ovataSN|18609]]SN|18609]]) and a cactus merged into one awesome tree with soft, bright green succulent leaves. Quiabentias grow so profusely in south-eastern Bolivia that they create their own forests. Because of their shiny leaves, a summer rainstorm makes the entire forest a dazzling sight, but people used to walk down the hills of the dry Chaco fear these trees because of the very dangerous falling twigs with long thorns; quiabentias have the most painful spines of all cacti.
Derivation of specific name: the species was dedicated to Karl Pflanz who discovered it in Bolivia.
Branches: Up to 4 cm in diameter with whorls of thinner branches at apex.
Areoles: White and circular.
Leaves: Fleshy, shiny, much thicker and broader than those of other opuntias, oval to diamond-shaped with pointed ends narrowed at the base, 4 cm long and 2 cm broad.
Spines: White, short and slender, pointing downward, up to 4 cm long.
Flower: Pale red.

: Quiabentia pflanziiSN|19007]]SN|19007]] is a low maintenance plant that tolerate considerable neglect and will naturalize, it is drought-tolerant; and suitable for xeriscaping, but their spines are so painful it is difficult to recommend them for home gardens. Easy to cultivate outdoor in dry, sandy or gravely, well-drained soils. May be grown in clay soils as long as drainage is good and soils do not remain wet, it is very adaptable both in acid, neutral and basic (alkaline) soils, but prefers a pH in the range 6 to 7.5.
Watering needs: Outdoors little or no water once established, in the green house irrigate regularly from March to October, keep fairly dry in winter, tolerate dry condition but suffer if exposed to prolonged and severe drought. A position at the base of a south-facing wall or somewhere that can be protected from winter rain is best for this plant, but is however resistant to moisture and rain.
Sun Exposure: Full sun (only), in semi shaded position wont produce many flowers.
Frost hardiness: They are not cold hardy, but may survived mild frosts if very dry.
Traditional uses: The leaves can satisfy the thirst in case of lack of water.
Propagation: Propagated by cuttings of segments at any time in the growing season. (Allow cut surface to callus over before planting).
