IF I lived in blessed Hawaii? I might pass on Broms and Tillys for attaching to my tree. It would be the super exotic primitive plants like titled. I once came on a board of them that is centered in southeast Asia,half of the writings were unreadable..but the plants? Long BLUE Huperzia Dalsomething's..and just fantastic plants that REQUIRE all year warm and humdity. And tree ferns...I have subtropical tree ferns,including the tallest Tree fern that can be grown in California,Cyathea medullaris...and one that is half that- C.brownii even if in habitat it's called the tallest tree fern species in the world. The Hawaiian Cibotium's can be grown here...at a very leasurely pace-lol. And never of course reaching the mass of tropical climate plants. As long as I'm asking..the Staghorns. Dean,you HAVE to have P.riddeyi!..'cmon spill the pics! A tropical fern forum would be great here. Steve Pope has a great collection in the UK under glass. Get him to post here and you have a world authority in tropical fern propagation. Oh well,think about it. I have to admit,I have a poor knowledge of Orchids. I wish I knew much more..some Catleya's actually do grow outdoors...precarious,but in long stretches and for years. Thanks all, Stan.
