Jack never had it so good.
There are fairy cushions to sit on in the top!
It's description claims that "Pandora's Giant Sunflower" is the "biggest in SL." I lack the resources to confirm this, but I will say that I personally haven't come across any other sunflowers of such staggering proportions.
Seeing the sunflower reminded me in mind of another larger than life plant: Stellar Sunshine's climbable beanstalk.
With a creation date of July 3, 2003 (I just learned about "inspect object"), the beanstalk is one of the oldest resident-built objects that I know of in Second Life. Legend has it, if you prove you can climb to the top unassisted (no flying no scripts), you'll be rewarded with L$500!
That red balloon wouldn't give me a tour.
I wonder if anyone has made it to the top. I sure can't.

Lordfly Digeridoo recently posted a link to snapshots of the 104 sims that were extant in March of 2004. Interesting stuff.
