Adding new color to a bouquet with dye isn't new, but the technology in making it look more professional has been advancing over the years. Changing the look of flowers is now as easy as applying paint, dye, or organic materials to get the desired look.
A clean flower is imperative when you go about the process of dyeing a flower. If you have even the slightest bit of dirt or grime on the flower, and intend on using a painting method, you could easily ruin the surface of the paint with imperfections. It's very similar to cleaning walls before painting rooms in your house; use warm water and scrub lightly.
Using spray paint is easy, as it allows for a quick application and a broad coverage area. Spray paint can be toxic, and can damage your flower if you don't obtain the right kind. Look for a brand that is non-toxic, and is organic so that there won't be interaction with the flower. A dead flower will quickly decay- backtracking your hard work!
If you feel you are an artist, you can apply dye directly to the flower and create truly inspiring designs. You won't have to pay much for the dye- you can use your average food coloring found in the cooking aisle at the local grocery store. Dyes tend to work best on light colored flowers, and not so well on the darker shades. Preferably you should work with a white bloom.
An easier approach to dye the entire flower could be to supply the dye in a vase of water, cut the end of the flower stem, and allow it to soak up the dye. In time, the flower will slowly start to change its color to the dye of your choice. The end result dyes the entire flower, each part to a different extent depending on circulation and original color. Black dye is popular for this trick.
There are special paints made for plants especially, should you want a more targeted solution. Be warned that these solutions are more expensive that previous methods described. They do have the benefit of being more safe to the flower, non toxic to those who handle the paint, and easy to apply. If you intend on creating a stunning piece of art it may be a good idea to suck it up and pay the extra money.
