I have a 3' tall Cardon that started as a cutting given to me about 10 years ago. It sat in the pot for four years without growth and without loss of mass. I almost gave the plant away when it suddenly started to grow. It showed signs of growth for one year (redness of new needles) and I have been getting about six inches of growth per year since then.
It shows no damage from the coastal humidity in Encinitas but is happier now in much drier Lemon Grove .

Propagation from seeds are easier than cuttings. There is Zero foliage on all the Pachycereus's. The flowers are open both night and day. Additional popular common names include: Cardón Gigante; Cardón Pelón; Sagueso; & Sahuaso.

Is a very decorative plant, in my garden (Can. Islands) every year I have flowers on different plants, fruits start to form, but never I have adult fruit with seeds. See photo added
I have a few cardons in my yard here in Phoenix, AZ. Cardons grow MUCH faster than their Arizona cousin, the Saguaro (I have 4-5 in my yard), which grows painfully slow. The blue green coloring is also distinctly different, as well as their propensity to branch lower and become more 'massive' than the saguaro. They are spiny when young, but they have fewer ribs than the saguaro and the spines eventually disappear when the plant gets mature. Cardons are more cold sensitive than the saguaro, but I don't have to do all that much in terms of protecting them where I am in NE Phoenix. Cardon Cacti survive more humid conditions that would prove problematic for the saguaro.
Like most cacti, they like good drainage and don't mind extra water in the summer, especially here in Phoenix. A beautiful cactus if you can grow it where you are.
