I am thankful that you posted the pictures of your longifolium. I have a few coming in; a compot of an awarded selfing and a flask of an AM/AOS x a HCC/AOS. When they get big enough they are going to go under my lychee tree. I made a wall out of CMU tiles about 30 feet across under the tree. I trimmed the tree and put the leaves/branches through a chipper/shredder and in the enclosure; about 2 feet deep of mulch. There are Phrags, anthuriums, gingers, vanilla, and cymbidiums in there now. The phrags were runts from a flask I got and just stuck them in the mulch, doing great too. It really is amazing how well stuff does when you naturalize them. Any tips about longifolium would be greatly appreciated...
