I found a way.
You could try selling all of our plants then set your computer's clock a day ahead and check the store keep doing that until you get the seed you want. What ever you do don't do it with plants because if you do that they will die or starve or something like that.

Just to let you know, it works!!!
I was stuck with out that seed and it worked. I got a Citrus Ball Cactus

No one do this... Not only can it do VERY bad damage to your games... but also can kill your compter. Besides, it's funner playing the game normally than cheating isn't it?

This does work. You have absolutely no basis to prove that it harms your computer. Changing your computer clock is no harmful than bookmarking a page.

If you are harping because it simply takes away game fun, then yes it can.

It can outdate your virus scanner and your spyware scanners... If you don't believe me, go ahead, don't come back angry if your computer breaks down.

This is called time-traveling and is considered cheating. Take my advice and DONT DO IT because there is little sympathy for time-travelers who mess up their game. Many applications rely on the computer clock will get messed up. Also, I think it can cause bad glitches in the games. PLEASE don't time travel.

Its called doing an u-p-d-a-t-e. You click that little button on your program that says update or check for current updates. You didnt know that? I know you wanted to contribute your two cents and all, but you are wrong. M'kay? Bah bye now. (gotta love SNL. oh you are probably too young to know what I'm talking about...)

You can mess up your game, just ask the people who have! And you can mess up your computer. I know, I've done plenty of timing in the past and it really does mess things up. It doesn't happen immediately usually, but it happens.

Changing your computer's system clock is not the same as bookmarking a page or doing an update. If your computer's system clock is inaccurate, your computer will be affected in many ways that are not immediately apparent. A computer's operating system relies on an accurate system clock, as do many applications, such as anti-virus software, calendaring, email, and many Internet sites. Anyone is free to change their system clock as much as they want, but if anything goes wrong you're pretty much on your own. Support is generally not available for self-inflicted computer problems caused by changing the system clock. Have fun with the game any way you like, but be aware that there are risks that you probably don't understand.

Way to go Fabledcash!!
