Well, when you get more stars in each world, you unlock a plants...most usefull ones at far future are:

Bonk Choy - Ancient Egypt - All 40 Stars

Snap-Dragon - Pirate Seas 20 Stars

Squash & Chilii Bean - Wild West 5 & 10 Stars (IN the Chinese Version Chilii Bean Works on Machines like Robo-Cone, Disco-Tro,etc.)

You should unlock Egypt, Pirate and West before going to Far Future....At first I jumped at Far Future imediatly after Egypt and got stuck at level 17...also don't unlock Kung Fu World, because it takes a lot of time to get a World Key there and there are not any important upgrades or plants!
