Man, I love this site. I get answers to questions I didn't even know I had! I have one of those in an area I haven't tamed yet. Thanks for identifying it, now I won't pull it out. Thanks!

Mooserider, I understand your reasonings and don't disagree completely. But, I work in ecological restoration. I am the one out there in these damaged abused public lands trying to restore them. The last thing we need (after ATVs and bulldozers and all that) is someone coming out and digging up plants that they think won't matter to anyone. You have no idea what research or restoration efforts might be going on and how your actions might be affecting that. You're removing food and shelter and erosion control and genetic diversity when you dig up plants to take home, even when they're not part of a restoration effort. Other critters are using those plants for something. Just because Seattle's been stripped, doesn't justify stripping other places to re-landscape Seattle. I've seen people pick flowers from rare plants. I've seen people cut trails (with a chainsaw!) through vegetative cover monitoring research plots. I see people let kids and dogs trample and dig and chase wildlife in reserves and parks. I've seen where our plants have been pulled up and removed after a big planting effort. People think, 'oh no one will care', but I care. And what about the animals and other plants that live there? they care too. The native plant nurseries propagate native plants by cuttings and divisions and seed and such, they don't go out and dig stuff up except for salvage efforts where land is going to be bulldozed for development. It's part of the code of conduct for ethical native plant propagation. The permit system for public lands was installed because too many people were digging up too much stuff. Rhodies and subalpine firs in particular were being stripped from the forests for landscaping Seattle gardens.

Now I'm puzzled as to why you asked for an id (using a photo dated 2015) if you already knew its name and had posted about it before? Your plant hasn't got typical Ixora foliage which is why I didn't recognise it. I'm thinking it could be Ixora 'Siam Ribbon' which has curled and distorted foliage. Reading up on its requirements I doubt it will flower in a terrarium as it likes full sun. Siam Ribbon

My best guess would have to be a Bird of Paradise. Most likely a white Bird of Paradise. I had a white one before, and it resembled your plant.
