A comfortable, well-watered Boswellia produces almost no frankincense. Three thousand years of trade, multiple civilisations built on the revenues, an entire overland road system constructed to move the stuff — all contingent on the tree being stressed, wounded, and growing in conditions where almost nothing else survives. Every plantation attempt has confirmed this. The tree has not updated its position on comfort.
Meet the plant Boswellia is a genus of about 25 tree species, all native to places that other trees treat as a firm no. Thin rocky alkaline soil, extreme heat, minimal rainfall. B. sacra in Oman’s Dhofar region takes this further: it grows from vertical limestone cliffs, roots wedged into rock fractures, no soil involved. It has been doing this for centuries. The approach continues to work, by its standards.
