I would go in and do it all by hand and then just duplicate the layers. Try cutting out a few pieces of grass out of green solids and then make move the vertex to the base of the grass piece. Now just give it a wiggle. You will obviously not want to have a camera pointing strait down for this =P
To make the daises, just animate stem (that you can cut out of a green solid) growing, animate a yellow solid scaling, and then animate a few peddles growing. After that, pre-compose it and move the whole thing around 😉
For the ground, I think the best thing to do would be to go outside and take a picture of the ground.
