Crassula quadrangularis gross

Botanical Name — Crassula quadrangularis gross

Common Name — Pyramid crassula

Plant Family — Crassulaceae


Crassula quadrangularis gross is an architectural succulent in the Stonecrop family. Native to South Africa, these plants like full sun, warm temperatures, and low humidity. In their native habitat they can be found on rocky slopes at high altitudes. This is a lovely, low-maintenance plant with interesting texture and shape that makes a great specimen for beginner and more experienced gardeners alike. 

Growth Requirements


  • Crassula quadrangularis gross prefer bright light, ideally three to four hours full sun. They will grow in light shade but may become leggy without enough light. 
  • They would thrive in late afternoon sun. If possible give them a spot in a sill with southern or western exposure. 

Temperature/ Humidity 

  • This arid plant likes high temperatures and low humidity. It will thrive in temperatures above 75°F, but avoid consistent temperatures below 45°F. Keep it indoors on a sunny windowsill during cooler months. 


  • This plant is super low-maintenance from a watering standpoint. Succulent leaves retain plenty of moisture so be sure to let the soil dry out completely in between waterings then water thoroughly, fully saturating the soil. 
  • In the winter, when these plants are not actively growing, ease up on watering even more. 


  • Crassula quadrangularis gross prefer a sandy, sharply draining soil. A cactus or succulent potting mix works great. You can also use regular potting mix amended with sand or fine grit up to 50% to improve texture and drainage. 


  • Flowers are small with a sweet scent and white to pink in color. Inflorescence grows as a dense terminal cluster at the tips of branches. Flowers typically bloom mid-spring to summer. 


  • Fertilization is not necessary, but if you are going to use one, be sure to use one specifically made for cacti and succulents.
  • Fertilize once every two weeks during the active growing season. This is limited to spring and summer in temperate climates.


  • These plants will propagate easily by stem cuttings or division. 



  • This plant is not particularly prone to pests or diseases. Root rot can be a concern if it is overwatered. 
  • Though this plant is low maintenance, it is always wise to keep an eye out for any bugs or spotting caused by disease. To help prevent any issues, prune away unhealthy leaves or stems.

Maintenance (pruning, legginess, repotting)

  • These plants prefer to be root bound, so you’ll only need to repot once every two years.


  • These plants are known to be toxic if ingested by animals and humans. Keep out of reach of children and pets.
