The Fouquieria columnaris is in bad health. I was suspicious it was a planting depth issue. That is the case. The photo below shows the original depth and the depth the plant was potted to.
Potting like this causes the plants stem to rot. It’s incredibly important to be precise when working with plants. F. columnaris is a rare plant occurring in just two regions of Mexico. The value of the gardens collection makes good care even more important. The photos below show the unhappy F. columnaris before and after repotting.
