Plants and Humans: A Symbiotic Relationship

Summary

Plants are not just a source of food, but they also play a crucial role in our lives. In this article, we will explore some interesting facts about plants shared by Joey Santo, a plant lover and botanist.

Geology and Plant Growth

Plants are affected by the geology of the area they grow in. Certain plants only grow on specific types of rocks such as gypsum, limestone, or serpentinite. For example, the California poppy grows on soils derived from serpentine rock, which is high in heavy metals like nickel and chromium. These metals are toxic to most plants, but the California poppy has adapted to thrive in these conditions.

Dispersal of Seeds

The dispersal of seeds is an important aspect of plant survival. Joey Santo explained that Joshua trees were originally spread by giant sloths eating the seeds, but now rodents are the main animals responsible for dispersing the seeds. Similarly, the Titan Arum plant attracts pollinators such as carrion beetles and flesh flies with its strong odor resembling rotting flesh.

Flower Anatomy

Flowers have ovaries, which are part of the compound sexual part of a flower called a pistil. When flowers get pollinated, they mature into fruits, which are also ovaries. This is why fruits contain seeds.

Invasive Species

Invasive species like kudzu are causing a loss of biodiversity in many American Southeast forests, and it is difficult to control. Kudzu grows rapidly, covering and killing other plants in its path.

Mulching

Joey Santo also explained the benefits of using mulch in gardening. Mulch helps to retain moisture, add nutrients, and keep weeds at bay. However, it’s important not to over-mulch as this can lead to problems like root rot.

Cactus Care

Overwatering a plant, such as a cactus, can cause it to rot if it cannot access the excess water. It’s important to water cacti sparingly and only when the soil is completely dry.

Orchid Origin

The word “orchid” comes from the Greek word for testicle. This is because the root of the orchid plant resembles the shape of a testicle.

Peyote Growth

The growth of peyote depends on the warmth and soil provided, and it can take up to four or five years for a seed to grow into a golf ball-sized button.

The Corpse Flower

The most interesting plant fact shared by Joey Santo is about the Titan Arum, also known as the “Corpse Flower.” This plant is native to Sumatra and is known for its incredibly strong odor that resembles rotting flesh. The smell is used to attract pollinators, which are mostly carrion beetles and flesh flies. The Titan Arum is also the largest unbranched inflorescence in the world, reaching heights of up to 10 feet tall. It only blooms once every few years and the bloom only lasts for a few days before it collapses. It’s a rare and fascinating sight to see in person.

Conclusion

Plants play a crucial role in our lives, and it’s important to understand their unique characteristics and needs. From geology to flower anatomy, there is so much to learn about the world of plants. We hope that this article has sparked your interest in the fascinating world of botany.
