How's this for tough?

Not many trees will grow right on the beach like this in Perth. 


Casuarinas and Norfolk Island Pines are pretty much it as far as I can tell.

Let me know if there's something else!

Casuarina sp. - City Beach, Perth

  1. C.equestifolia are planted extensively in coastal areas. Indeed all casuarinas including local ones suit beach locations. C obesa is salt tolerant and great in estuaries. Agonis flexuosa, A heterophylla true but also A columnaris. And howbout Olea europa? These can survive and also be productive in maritime locations. And those other things that aren't quite trees but do a similar job - Palms. The iconic Washingtonia, the graceful tropical varieties and the robust Phoenix. Head down to Bunker Bay and even further south to Denmark, Palling River etc and Melaleucas are the predominant beach tree, likewise on Rotto. In the Leschenault inlet tuarts form a grove. Plenty trees to choose from.

    1. "Plenty of trees to choose from"

      Hmm….not convinced about that. I am talking about Perth, not the south west which is a bit different (not as harsh). I don't think I'd be too optimistic about olives on beachfronts here in Perth. Even Agonis (WA Peppermint) would struggle to form anything decent right on the front here. Palms? Maybe, but pretty useless as a "tree" as you say. If you want a full canopied, healthy tree right on the beach here, I still can't see anything other than Casuarina (or Araucaria) doing it for you over the long haul. All the other stuff ends up stunted and/or burnt in my experience. And I think this raises a good point generally: that we need to choose trees that will not just survive, but thrive in the locations we're planting. This has been a problem for too long in Perth with councils planting silly things like Magnolia and Chinese Tallow etc into the Perth sand plain. They survive, but deliver very little amenity.
