I emphatically disagree with seraphima. Of course you could survive on natives. People have done it for most of their history on earth, when we knew nothing about agriculture! People have been around for 200,000 years, and agriculture has only been known for the last 10,000 years. Although most people here would not know edible natives beyond a few berries, it's because they simply don't know the native plants. You could survive on a vegetarian diet here with natives. It would consist of berries, fresh in summer and dried in winter, roots of camas and ferns year round, greens of fireweed and salmonberry in the spring. You can even eat the inner bark of trees in a famine. Of course, this is assuming you only mean using the plants. The native peoples here ate a lot of fish because it was very abundant and easier to get than plants. The main problem with surviving only on natives is that it would be BORING! Common garden vegetables come from all over the world - potatoes and tomatoes from south america; carrots and broccoli from europe; apples, onions and lemons from asia. How much of your diet comes from the tropics? I know a lot of mine does. In comparison to all this diversity, of course only eating natives would be boring. But that doesn't mean you couldn't survive perfectly well on it.

I remember thinking Idaho's nativity set was attractive but cannot remember exactly what it looked like. I bought this one at Costco last year and saw that they brought it back again this year. Not sure if this is your taste. Here is a link that might be useful: nativity scene

The miss-naming of exotic plants as natives is not always the fault of the nurseries, though most nursery people have almost zero botanical knowledge and this does not help. There are actually two native species of Myrraya. Murraya ovatifoliolata occurs in dry or coastal rainforest from south Queensland to Cape York and to the Kimberley in WA. There is another one, a large and showy plant, that occurs on Cape York Peninsula and botanists insist on calling it Murraya paniculata though it does not look much like the exotic version. This is where mistakes come about. Someone will look up a herbarium list and it says Murraya paniculata occurs in Australia therefore the ones we are selling must be a native. Another one is Syzygium malaccense. The Australian one looks very little like the Asian one and the fruit are completely different. Even the common Weeping Fig (Ficus benjamina) occurs in Australia, but all the ones sold in nurseries are from Asia. Here is a link that might be useful: Rainforest Magic

Do you have a picture? If getting yellow leaves it could be a watering issue. The leaves foldedup before? Where was it when the leaves would fold?
