Totem Pole
Pachycereus schottii f. monstrosus
"Smooth columns without spines"
Native to
A monstrose form of a species native to Baja California

History
A brief account
A rare spineless mutant of the senita cactus, discovered in Baja California in the early 20th century. Its lumpy, sculptural columns recall carved totem poles. A favourite of modernist gardens for its near-architectural form.
How to care for
Totem Pole (Pachycereus schottii f. monstrosus) grows best when its natural cycle of strong light, freely draining soil and measured watering is respected. Give it full direct sun. Water it according to its seasonal needs: sparingly in summer; nothing in winter. Plant it in lean, very fast-draining mineral mix. A container with an unobstructed drainage hole is essential, because moisture lingering around cactus roots can quickly lead to rot.
Keep its temperature needs in mind: 5–35°c. frost-tender. During active growth, check the compost before watering rather than following a rigid calendar, since heat, light and pot size all change how quickly it dries. Reduce watering during cool or dormant periods, keep the plant well ventilated, and wait until the growing medium is dry before watering again.
How to propagate
Cuttings root with patience; growth is slow. Take material from healthy growth with a clean blade or tongs, then leave the cut surface in a dry, shaded place until it forms a firm callus. Set it into a dry, gritty medium and introduce water sparingly only after roots begin to develop.
Young cacti are especially vulnerable to excess moisture. Use a small pot with excellent drainage, provide bright filtered light while roots establish, and move the new plant gradually into the light, temperature and watering conditions preferred by a mature Totem Pole.
