although most flowers can be successfully preserved in either solution 1 or 2, some flowers require the use of the other solutions. If the color cannot be preserved in any one of the solution, two or more of the solutions may be mixed in order to obtain the proper acidity or alkalinity. Generally, specimens whose color ranges from pink to red are preserved in solution 1 and those whose color ranges from green to blue are preserved in solution 2. Some blues and greens may be treated in solution 3. Intermediate colors between red and blue may generally be preserved in either solution 1 or 2; or in solution 2, with the pH adjusted to the proper point at which the color is preserved. Certain reds may be preserved by treating the specimens in solution 2 followed by dipping in solution 1 until the desired color is obtained. Others may be treated in solution 7. Most orchids are best preserved in solution 5. Certain whites that have a tendency to turn to orange or brown may be treated in solution 4; however
