You can do it with rattle cans, I use graffiti paints that are quite cheap, I prime with mnt 94 amazonas green and then just give them a quick dash with a lighter green ink, but it works with rattle cans as well, but I prefer using my airbrush to lighten them up

Also, get shitloads of paint stir sticks to allow you to mass paint the plants.
