I planted one on the first property we owned in Fallbrook, then planted one on the second property that we sold two years ago. I love the plant so much that I should have planted many of them and here where nurseries are few and far between (good ones), it is on my list of wants. I do not know if it will make it here, though I'm currently growing some Aussies here and have a friend 45 miles north who grows a lot of Aussies. The small Botanical Garden in Brookings, Oregon has leptos and leucadendrons, etc., so I'm hoping that mine will do okay here. Brookings is a bit more of a Banana Belt due to the "Chetco River Effect", much like our Santa Anas in SoCal...warm inland air flowing from the interior to the sea. I'm only guessing at petersonii, if it is not lemon scented, then it's an incorrect guess.
If I thought for sure that something was green...and Janet told me it was red, I'd believe Janet....lol..
