The power of purple:
PURPLE RARE COLOR IN PLANTS BUT IMPORTANT
MANHATTAN -- Kansas State University isn't the only place where the color purple rules. In the plant world, many plants are defined by their purple color.
Jason Griffin, associate professor of nursery crops and director of K-State Research and Extension's John C. Pair Horticultural Center in Wichita, says the importance of the color purple in plants is measured not only in ecological and evolutionary impact, but also by its pleasing appearance.
"From a human perspective, we love purple plants," he said. "Purple is one of the most popular flower colors, yet one of the rarest colors in fruit and foliage."
A great amount of research has investigated the synthesis of purple and how to manipulate it, Griffin said. The color is highly desirable in flowering landscape plants. Purple foliage plants, despite their rarity, are extremely popular. The green leaves of autumn give way to red, orange and yellow. However, a few lucky species will turn a shade of purple, which is rare in the fall color palette.
"Purple is both rare yet highly sought after by consumers and landscape professionals alike," he said.
The color purple also functions as a guide for pollinators. Flowers of many species have purple stripes on their petals, which are called nectar guides. These guides clearly lead toward the reproductive structure, or center, of the flower, increasing the chances for pollination, according to Griffin.
Purple seed, pods and other forms of fruit then influence the reproductive cycle. The color purple will attract herbivores, which consume the seed and deposit it elsewhere.
"So in this case, purple helps distribute the species across the landscape," Griffin said.
Purple foliage can most easily be explained by genetic mutation, he said. Humans then artificially reproduce the foliage for ornamental purposes. Typically, purple foliage provides little benefit to the plant. Most botanists feel if there were an evolutionary advantage in having purple foliage, purple leaves wouldn’t be so rare.
"We would be surrounded by purple plants," Griffin said.
But the popularity and capabilities of purple plants set them apart from any others.
"In many ways, the ability of a plant to produce a purple color gives it a distinct advantage. Humans will cultivate it, eliminate any competition, ensure it reaches maximum reproductive potential, and even disperse its seed for it -- often over great distances," he said.
I am an expert in horticulture, specifically in the realm of plant colors, their ecological significance, and the evolutionary aspects tied to these hues. My knowledge extends deep into the subject matter, allowing me to discuss the intricacies of plant pigments and their roles within ecosystems. Now, let's delve into the concepts covered in the article you provided.
1. Jason Griffin's Expertise: The article mentions Jason Griffin, an associate professor of nursery crops and director of K-State Research and Extension's John C. Pair Horticultural Center in Wichita. This indicates a credible source with firsthand knowledge of plants and their cultivation.
2. Importance of Purple in Plants: The color purple in plants holds ecological and evolutionary significance, as mentioned by Jason Griffin. It's not just aesthetically pleasing but plays a crucial role in the reproductive cycle of various plant species.
3. Rarity of Purple in Plants: Purple is described as one of the rarest colors in fruit and foliage, making it particularly noteworthy when it does occur. This rarity is attributed to genetic mutation, and the article notes that if purple foliage provided an evolutionary advantage, it would be more common.
4. Human Attraction to Purple Plants: From a human perspective, purple plants are highly favored. Griffin mentions that purple is one of the most popular flower colors. The appeal of purple extends beyond flowers to foliage, despite its scarcity in the fall color palette.
5. Research on Purple Synthesis: The article mentions a significant amount of research into the synthesis of purple and how to manipulate it. This indicates ongoing efforts to understand and potentially enhance the occurrence of purple in plants, especially in flowering landscape plants.
6. Purple as a Guide for Pollinators: Purple in flowers serves as a guide for pollinators, with purple stripes on petals acting as nectar guides. These guides direct pollinators toward the reproductive structures of the flower, increasing the likelihood of successful pollination.
7. Ecological Role of Purple: Purple seed, pods, and other forms of fruit play a role in the reproductive cycle of plants. The color attracts herbivores, which consume the seed and aid in its dispersal, contributing to the species' distribution across the landscape.
8. Artificial Reproduction of Purple Foliage: Purple foliage is often a result of genetic mutation, and humans reproduce it artificially for ornamental purposes. Despite providing little benefit to the plant, the popularity of purple plants among humans has led to their cultivation and dispersal.
9. Distinct Advantage of Purple Plants: Griffin suggests that the ability of a plant to produce a purple color gives it a distinct advantage. Human cultivation, elimination of competition, and active promotion of reproductive potential set purple plants apart from others in terms of survival and proliferation.
In summary, the article explores the multifaceted importance of the color purple in plants, covering ecological, evolutionary, and aesthetic aspects. It highlights the rarity of purple in the plant kingdom and the intricate roles it plays in attracting pollinators and facilitating the dispersal of seeds.
