Why Cupressus Lusitanica?
When it comes to choosing the right Cypress species, Cupressus lusitanica is our go-to. It’s fast-growing and perfectly suited to New Zealand’s climate. Its timber is almost indistinguishable from its cousin Cupressus macrocarpa in both look and properties. We have found Cupressus lusitanica to be more resistant to fungal attack, in fact it is difficult to grow “macrocarpa” in the North Island. Most of what you think is macrocarpa is actually lusitanica
What We Know About It
Cypresses have been growing in New Zealand since the 1860s, part of the early effort to find sustainable alternatives to our native forests. Lusitanica, originally from Central America, quickly proved its worth. Over the years, New Zealand’s research into this species has been huge, showing just how good it can be for timber production.
While it never took off on the scale of Pinus radiata, that’s mostly because radiata grows super-fast and soaks up preservatives easily. But here’s the thing—people today are rightly wary of chemically treated timber. That’s where naturally durable species like Lusitanica shine.
How Durable Is It?
The heartwood of Cupressus lusitanica is classified as moderately durable—expect around 10–15 years in the ground, and way longer out of the ground. A house can be built almost exclusively of lusitanica and be within code. Does this mean you can use it for cladding and fascias? It certainly does but make sure you use heartwood. Panelling and sarking are perfect end uses for knotty grades and sapwood. In fact lusitanica is suitable to use anywhere inside a house where you can be seen in the final inspection. The sapwood, like most softwoods, is perishable when in contact with water, but when used in dry, protected spaces indoors, it holds up brilliantly.
And let’s be real: more and more people are keen to avoid timber that’s been doused in chemical preservatives. Lusitanica offers a safer, more natural alternative.
What Does It Look Like?
Think warm honey tones, a fine even grain, and—if you quarter-saw it—a shimmering, almost silky look that’s a real show-stopper. It’s a bit like native Kauri, but with its own unique charm. The grain is full of character making it stand out beautifully from species like radiata pine.
Density and Strength
Cupressus lusitanica has similar density and strength properties to radiata pine and even NZ Kauri. It’s reliably strong and light enough to work with easily. Just be sure to pre-drill nail holes to avoid splitting.
