Photo manipulation in Photoshop

it's hard to explain but here it goes, copy another layer of the photo so you have two layers of the same thing the original photo and the copied, then trace out the plant you want colored and delete that portion out of the second layer, then change the second layer to black and white with some command that I forgot and that will be it.

Copy your picture into another layer......you will then have two layers. A background layer and copy of that. Remove the color in the copy layer by hitting shift+ctrl+u. Then select the marquee tool and suround the area you want to be color. Hit delete. It will delete the highlighted area allowing the color layer to show through.

Ahhhh yes... that's was what I was getting at, well said.

Okay, here's the one layer method...

Choose the marquee selection shape of your choice (rectangular or circular), set the feather amount (if desired) and select the area you want to highlight.

Now, press [ctrl]+ to invert the selection.

Finally hit [shift]+[ctrl]+ (this is the same as doing Image, Adjustments, Desaturate) to desaturate the selected area.

You can see some info on this here.
