Isn't this a DYI project?

Not quite the same, but similar-ish.

they might still have some at Cost Plus world Market's- I saw them earlier this year, but it varies by store and quantities are limited- click here.
Otherwise, i know a store in Palm springs sold them called Soho late last year, but not sure if they still carry them... Hopefully more stores will carry them as they are gorgeous!

we got a couple of sets of those in white (they come in a handful of colors). they're from Phillips and are called Aurelle lawn stakes. the branches can be moved around a bit to get the desired effect. We got ours @ Amazon.com but the Phillips website also has them for sale...

i purchased a couple of those months ago on Valencia St (one of them broke right away though). i believe it was Therapy, between 16th and 17th St.

Delia's used to have red flower branches in their "room" section that were more reasonably priced than the ones above, but they seem to have taken them off the site?

Buy branches at the flower market and twinkles lights and put them in a large floor vase. I've been doing this for years and it's really inexpensive.

Courtney Cox's bedroom in "Dirt" had very similar branch lighting, with red lights. I've been looking for something similar ever since. Thanks for the amazon link chris!

I've seen some in Montreal's chinatown as well as in another *chinese/japanese/asian themed boutique*...

I bought a red branch and a white branch at Ma Maison in San Francisco.

I bought mine about a year ago, but I think the owner would be able to tell you where to get them if she doesn't still carry them.

I'm pretty sure they're from Nature and Decouverte in France. I see them everywhere here. Maybe there's a US source too?

haven't we seen these, both red and white, in Chinatown?
or are these slightly spiffier versions?
i'm pretty sure the ones i saw at Therapy were exactly the same ones i've seen in Chinatown.

I think I saw these in the window of "Does Your Mother Know" on 18th St. between Castro and Collingwood.

I've got some that I bought at urban outfitters a while back, but I'm pretty sure they discontinued them. would love to get some more because my foster kittens all but destroyed them.... :(
