The world of plants is a mesmerizing realm filled with an astounding array of colors, shapes, and textures.
Among the myriad plant species, one fascinating leaves category stands out: Plant with purple leaves.
Purple leaf plants have captivated the attention of gardeners, horticulturists, and plant enthusiasts alike. So do you know how to make purple leaf plant identification?
What purple leaf plant names are there? And how to take care of them. Let’s explore the following with us.
What Are Purple Leaf Plants?
The purple-leaf annual plants have dark leaves due to the increased concentration of anthocyanins in the foliage.
This pigment causes the leaves to turn purple from light purple to pale pink, burgundy, deep purple, amethyst, and deep purple, even almost black.
Vibrant purple foliage can also add bright color to your beautiful garden.
Some famous plants with long purple leaves in many gardens are Tradescantia pallida, Cordyline fruticosa, Strobilanthes dyerianus, etc.

Method of Purple Leaf Plant Identification
The most straightforward approach is to inspect the purple leaves plant without any tools visually.
Purple leaves are uncommon among garden shrubs, ornamental plants, and houseplants, making them stand out uniquely.
Certain houseplants with purple foliage may exhibit dark purple leaves accompanied by green edges.
Additionally, some tropical plants display purple-colored leaves, and some varieties even possess variegated patterns of purple.
When identifying plants with purple foliage, it can be helpful to know that many purple-leaved varieties share the same leaf shape and size as their green-leaved counterparts within the same species.
This characteristic holds for plants like Cercis canadensis, which exhibits heart-shaped leaves similar to other Cercis or redbud varieties.
Similarly, Japanese maples (Acer palmatum) have palmate leaves with pointed lobes, like different palmate maple varieties.

Purple Leaf Plant Care Tips
To take care of purple leaf flowering plants, we must pay attention to 5 main factors as follows:
Soil & Watering Needs
Considering its original source, this purple-leaf flowering plant can tolerate slightly humid conditions when watered.
However, since it is a succulent and not a cactus, it cannot withstand prolonged periods of drought.
Therefore, you need to maintain moderate soil moisture. During spring and summer, water regularly limits its growth potential.
However, ensure it doesn’t exceed 1 inch of water every six days or longer—especially during the summer.
Frequent watering for the purple leaf plant, when temperatures are high, will help maintain its structure and shape.
Always check if the top two inches of soil have completely dried before watering the plant again. Needless to say, you need a well-draining potting mix to prevent root rot.
If the plant starts to wilt, check the soil for moisture.
The best time to water the purple leaf plant is in the evening, which can be highly effective as the moisture absorption is at its highest. Most indoor plants thrive when the soil has good drainage.
In addition to providing a moist and fluffy soil layer, you should also consider adding perlite or pumice, as they are excellent for enhancing the soil’s moisture retention capacity.
The tree develops the most vigorous branches and leaves in the new planting period. This will disperse the nutrient source, so pruning is essential.
Remove damaged, wilted, slanted leaves so the plant can focus its nutrients on developing main branches and healthy main trunks.
Although most purple-leaf plants perform photosynthesis to survive, they also require additional nutrients to support their growth processes.
The nutritious meal they need comes from fertilizers, which help keep the plants happy, healthy, and vibrant.
Indoor purple leaf plants generally thrive when fertilized with a balanced 10-10-10 fertilizer (Nitrogen – Phosphorus – Potassium).
These plants rely on nutrients from the soil in their pots and fertilizers to sustain themselves. The plants will wither and die without repotting or supplementing the soil with fresh nutrients.
If your plant is flowering, you can purchase a fertilizer with a high potassium content. If it is a foliage plant, you should fertilize with a nitrogen-rich fertilizer or use nitrogen-rich potting soil.
The plants also require essential trace elements, which can be supplemented by adding soil or fertilizers to ensure survival.
Dealing With Common Pests and Diseases
When newly planted, many trees have weak resistance because of changes in the living environment.
To limit pests and diseases, you must fertilize large and healthy trees, use biological products to kill plant pathogens, remove infected plants to avoid spreading to other plants, etc.
In addition, it should be noted that the time of planting trees is still fragile; all impacts on trees and the ground should be limited as much as possible.
If the plant shows signs of pests, such as powdery mildew, you should use alcohol to wipe the leaves and roots, then use organic drugs to control pests.
If the disease is severe, it is necessary to let the tree out and treat it.
Tips to Protect Purple Leaf Plant
When starting with a new purple leaf plant, many people struggle because they are unsure how to care for it and neglect to seek information properly.
This can result in ineffective care efforts. Therefore, it is essential to note the following:
Plants need water, but that doesn’t mean watering excessively is good for purple-leaf plants. Water is a vital nutrient for plants, and each plant has unique water requirements.
It is essential to water adequately without overwatering, which can lead to root rot and plant damage.
The ideal time for watering is early morning or late afternoon when the temperature is more relaxed. There is no need to water excessively for indoor plants; flooding every two days is typically sufficient.
The plant needs fertilization immediately after planting to promote rapid and healthy growth.
Fertilizers provide essential nutrients to the plant, influencing its development and productivity during harvest.
The appropriate fertilizer formula depends on the plant species and growth stages.
Avoid over-fertilization, as it can cause burning and plant death, and under-fertilization can result in nutrient deficiencies, stunted growth, and delayed development.
Use a sterilizing agent on the pot and replace the soil if you notice any signs of infection or disease symptoms to prevent reinfection of your plant.
You can add garden charcoal to the pot to improve drainage, especially if the roots show signs of rotting.
Before starting to plant something, it is essential to do thorough research.
Especially for ornamental plants with purple leaves, you should find a way to make purple leaf plant identification look like a bonsai.
Regardless of the type of tree, you need to remember that our primary goal is to create conditions for the tree’s roots to grow as strong and fast as possible.
This will help the tree to stand and support the development of branches, buds, and leaves.
This article will provide you with excellent knowledge about purple leaf plants, making it easier for you to grow this ornamental plant.
