No.

The arar tree is highly flammable and does not belong near structures.

Two laboratory studies reach the same practical conclusion. Annals of Forest Science explicitly placed arar among its highly flammable species after examining combustibility and sustained burning in fresh and dried fuels. The European Scientific Journal also gave the tree its high-flammability rating, note 3. On that study’s scale, note 3 applies when fresh material ignites within 65 seconds.

A related measurement helps show what that finding looks like under controlled conditions. The FLAMITS database reports that a live leaf sample took 15 seconds to produce flames in a calorimeter during September sampling. That figure measures time to flaming for one prepared sample under one test setup. It is not by itself a universal prediction of how every arar tree will behave outdoors, and FLAMITS does not turn unlike measurements into a single recommendation.

Arar, or Tetraclinis articulata, is a tree in the cypress family. Here the recommendation does not rest on the database number alone: the two published laboratory classifications identify high flammability directly. For landscaping near a building, those findings support choosing something else and keeping arar away from structures.

How to read this page

The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.

Conditions in the fire evidence

These describe tested or rated plant material. They are not horticultural maintenance instructions.

Where its sources say to plant it

Placement rules below use each source's own distances or named zones, tied to its rating. They are not interchangeable with the directory's current Zone 0 guidance.

The evidence

Grouped by what each source concluded. Primary evidence rated the plant itself (a lab, field program, or original curation); corroboration compiled or republished another source's rating and resolves to its root lineage.
