I thought i would share some simple way of producing the flowers seen on this page. First of all color and tone settings are all relative to the design in question so there wouldn’t be a point displaying the #hex since the end result would be different, adjust it to fit your needs.
Alright lets start of by creating the “green grassy thingy” the flowers should be attached to.
Step 1. Create a new layer, select pencil tool 
and with a size of 1px randomly draw something along your canvas or design, something like this.
First we will add some blending effects to get rid of the flat look, see the result here. We then we duplicate the layer add a bit of gaussian blur, Filter -> blur -> Gaussian blur.
Go back to your original layer and lower the opacity to about 25-30% depending on the level of blur you have applied, this is to still have some definition (again it all depends on what feel you are going for).
Step 2. To speed things up we can use a custom shape 
from photoshop instead of freehanding it with the pen tool 
. The custom shape i’ve used is the star, draw it out on your canvas and select all the inner points (use the pen tool, hold down ctrl + shift to select all the path points) hit Ctrl + T and hold down alt + shift and drag one of the corners towards the middle, you should end up with something similar to this.
Next we want the corners to be round and not sharp as the stars original shape. Select the pen tool hold down your alt key and you would get the convert point tool 
, so click on your outer corner and drag untill you are happy and do so with all 5 corners and you should have a flower shape. Resize it to a more realistic size of your document then apply some basic blending effects to make it stand out.
Final step. This is really simple, take the ellipse tool 
hold down your alt key and draw an even circle to fit in the middle of your flower apply some blending effects and it should all be done.
A good thing is to have everything in layer sets so you can duplicate the flower and flip i, twist it and turn it however you want to make it more random.
This tutorial is based on verry simple photoshop tecniques and only takes 5 minutes to do but with good results. If you wanted to you could go crazy and do different types of flowers, colors add some leaves or whatever you feel would fit.
I also added a wallpaper with the re-use of one flower, enjoy
