A few weeks back I stopped at Len's place to buy a nice trachy nova, and Len showed me around a bit. He's a modest guy, but I feel his garden deserves to be featured on PalmTalk, it is simply stunning. If you wonder how his palms end up so dark green, try dolomite lime, that's Len's secret sauce. (It's mine too, along with good ol' urine.)
His Vista garden is inland far enough to supposedly be 10a, but looks more like a 10b zone to me. He would be better able to comment on the hardiness zone.
His bismarckia is just in the perfect spot, towering over a magnificent lagoon-style pool. Notice the kentia on the right, not much frost damage from last Winter, shows you how mild of a spot Len has.
I am going to put down what I remember from taking these pictures, but he will have to correct any of my comments. One of the next two photos is the old dypsis betafaka, which is not the real betafaka, but was referred to some as the "ugly betafaka" but it doesn't look ugly to me. He says it puts on a lot of growth in Winter.
