What Is Graptophyllum Pictum?
The Graptophyllum Pictum is also known by its botanical name, Caricature Plant. It’s also a synonym for Justicia Picta. It sometimes goes by the name Joseph’s Coat; however, very few use it. Whatever common name you choose, this perennial remains well-known for its vibrant and variegated foliage. This tropical plant from the Acanthaceae family has chocolate-purple foliage with creamy pink oblong-shaped ones.
This plant is used in Southeast Asia and India for cuts and specific skin issues. An infusion from this plant is taken as a remedy for constipation while the sap is dripped into the ear for earache.
While the rest of this article focuses on indoor growth, this Graptophyllum can be grown outdoors in hardiness zones 10-11.
Origin And Family
The Caricature Plant belongs to the Graptophyllum genus in the Acanthaceae family. It comes from the forests of New Guinea. This plant has become known in recent years, thriving in most households with moderate humidity.
William Griffith reclassified the Caricature Plant in 1854. It produces small pink, purple, maroon, or reddish-brown flowers during summer.
Where To Buy
Graptophyllum Pictum is available at a nursery or a big box home improvement store in your area. It’s usually better to buy one on Etsy, though, where you’ll find more reasonable prices (plus, they have the best packaging!). Etsy also allows us to buy straight from plant lovers who grow this variety in their homes.
The Graptophyllum Pictum’s reasonably affordable price range is from $20 for smaller plants to $30 for larger varieties. I must warn you, though, that this plant is in high demand and is in short supply these days.
Graptophyllum Pictum Plant Size
On average, the Graptophyllum Pictum grows up to 2-3 feet tall and 2-3 feet in indoor spaces. It usually grows at a fast pace, especially when it’s positioned near a south-facing window or west and east window.
Graptophyllum Pictum Care Needs
Though Graptophyllum Pictum is not a complex plant to care for, growing it to its maximum requires certain conditions. The Graptophyllum Pictum, with its vibrant and variegated foliage, loves humidity and needs relatively moist soil to thrive.
Water your Graptophyllum when the top inch of the soil is dry. To properly hydrate the soil, make sure your pot has good drainage. Do not be afraid to drench the soil during watering schedules thoroughly. As for the light requirements, this versatile plant can tolerate full sun to partial shade.

The Justicia Picta is considered easy to care for because of its light, water, and humidity requirements. To grow this plant properly, you must be precise about the amount of light and well-drained soil.
When grown indoors, the Joseph’s Coat plant grows to 2-3 feet. It develops the fastest during early spring and summer.
Most Graptophyllum species, including the Pictum, have a fast-growing speed.
This potted plant wants good drainage and can look good in various pot sizes. A large-sized plastic, terracotta, or clay pot works fine.
Drainage holes are a must for Caricature Plant because it needs to be watered when the top inch of the soil is dry.

Graptophyllum Pictum typically needs to be repotted once a year or when you see its roots pushing out of drainage holes. When this happens, carefully remove the plant from its pot but be careful not to disrupt the leading root ball. You can then transfer the plant into a larger pot. Use the same substrate on the new plants’ pot so it can adapt quicker.
The Justicia Picta is an easy-to-care-for plant that needs standard commercial potting soil to stay healthy. If you plan to prepare your soil mix, we recommend adding peat, perlite or sand, turf soil, or humus.
Your Graptophyllum will appreciate the soil being kept relatively moist at all times. Nonetheless, drainage and aeration are essential requirements for all soil types.
Here are some potting mixes we recommend:
You’ll need a soil pH of roughly 6.5-7.5, which is slightly alkaline to slightly acidic, for Joseph’s Coat. If you are concerned about acidity in your soil, you may test it with a simple pH testing equipment that is available online.
If you suspect that the pH is too high, you can reduce it by adding sulfur or aluminum sulfate.
Meanwhile, if your soil’s pH is too low, you may add baking soda, calcitic or dolomitic lime, or wood ash.
Proper watering is essential for Caricature Plant. Overwatering heightens the risk of illnesses such as root rot. Watering too little might cause your plant’s roots to dry out, especially on hot days. In general, Caricature Plant should have a growing medium that is relatively moist.
There is a simple method to confirm if your plant needs to be watered. Pierce a wooden skewer or a pencil into the container to inspect whether any moist, muddy dirt stays. Alternatively, you may feel with your finger for dampness. When the top inch of soil has dried, it’s time to water your plant.
The survival of your new plant depends heavily on a porous pot with drainage holes and an aerated, chunky soil mix to help eliminate excess moisture.
The light condition for this versatile plant differ. It can tolerate full sun to partial shade for 6-8 hours daily. In most cases, depending on the season, you can place this plant in front of a sunny window, near a brightly lit area, and south, west, or east window.
You’ll notice your Graptophyllum Pictum produces more rich and darker-colored foliage when exposed to bright light, which is not a terrible thing for this beauty. It doesn’t necessarily mean that this tropical plant needs more light when you get denser leaf growth.
A slow-release fertilizer is ideal for the Graptophyllum varieties.Covington Plant Food & Fertilizer Liquid Concentrate , for example, would work. Other cheaper fertilizers contain heavy salts, so we recommend getting one from our trusted affiliates. In spring and summer, feed your plant every three months.
In the winter months, growth naturally slows down, so you don’t need to fertilize.
Avoid supplying fertilizers to your Caricature Plant, as it may severely damage or even kill it.
Propagating Graptophyllum Pictum
There are different ways to propagate a Graptophyllum Pictum. Follow the instructions outlined below for each approach to increase your chances of success.
Stem Cuttings In Soil
Cutting and planting is the most efficient way to propagate a Caricature Plant. Seeds are sometimes available but might be challenging to find and start. Spring is the best time to reproduce your plant.
1. Cut. Find a healthy stem section with new growth and at least one node. Cut this section using clean gardening shears.
2. Plant. Directly plant the cutting into sterile soil.
3. Maintain. Maintain moist soil and keep the air temperature to approximately 70°F.
4. Cover. Enclose your plant in a plastic bag to confine humidity and encourage faster rooting.
5. Rotate. For leveled growth on all sides, rotate the pot now and then and place it in its ideal location. Given plenty of time to grow, you’ll soon see a new Graptophyllum sprout.
Stem Cuttings In Water
A Justicia Picta can be propagated in water with six simple steps.
1. Cut. Cut a section from the stem with new growth and at least one node.
2. Submerge. You can place the cutting in a transparent container or a glass of water to monitor root growth.
3. Maintain. Next is to store the cutting in a bright, shaded area with good airflow.
4. Refill. Replace the water every 3-5 days to avoid bacterial infection.
5. Transplant. After two weeks, check for progress; then plant the cutting into a sterile potting mix if the roots are about an inch or longer.
6. Wait. Your new plant may look wilted at first, but this is normal because the roots need to adjust to the soil. At this point, avoid applying fertilizer or any treatments until your plant has gotten the chance to stabilize. A new foliage growth will soon follow.

Humidity And Aeration
This Graptophyllum is an exciting plant that prefers moderate humidity.
If your Graptophyllum Pictum has curling or crispy leaves with brown edges, you might need to get a humidifier. This device is designed to continuously emit steam and considerably increase the humidity in a room.
Like most Graptophyllum plants, your Joseph’s Coat will do best in a cool-to-temperate location. Keep the temperature between 60-80 degrees Fahrenheit.
Houseplants can be sensitive to extreme temperatures, so ensure you keep your Joseph’s Coat away from heat sources such as vents, hand dryers, furnaces, and other appliances. In the same way, don’t expose your plant to chilly drafts and frost spells during the winter, as it may suffer cold damage.
If you’re lucky, you might be able to witness your Caricature Plant blooming with a little pink, purple, maroon, or reddish-brown terminal clusters of flowers during the summer months. However, this doesn’t typically happen in an indoor growing location.
The Justicia Picta is not hazardous to children or pets. According to the ASPCA, it will not harm dogs or cats if swallowed since the plant does not contain hazardous substances.

Pests, Diseases, And Other Problems
Overall, I would say that the Graptophyllum Pictum is a disease and pest-resistant plant. Here are some quick tips for curing common ailments and general suggestions to keep this plant healthy.
Spider mites are common pests, particularly among Joseph’s Coat plants. Initially, spider mite damage will appear as small, brown, or yellow patches on your plant’s leaves. You might also observe your plant’s slowed growth.
To eliminate spider mites, begin by washing off your Joseph’s Coat with a garden hose, sink nozzle, or a pressure sprayer. In addition, you can spray neem oil or insecticidal soap on the plant leaves, but make sure that you cover all surfaces, including the underside of the leaves!
Of course, another option is to introduce natural predators of spider mites such as ladybugs, lacewings, and Stethorus picipes beetles (dubbed as the “Spider Mite Destroyer”). The cool thing about these bugs is that they feed on spider mites while not harming your plant!
Whiteflies are tiny airborne insects that immediately fly around when a plant is moved. They are particularly attracted to the Caricature Plant. They feed on leaves but rarely cause the death of plants.
If you like the taste and smell of herbs, keeping them near your pest-ridden plant has an added benefit! The aroma of mint, parsley, and cilantro are known to repel whiteflies.
Managing a heavy infestation necessitates the use of a pesticide. Here are several popular Amazon products we recommend against whiteflies:
Scale insects seem like lumps on the stems or leaves of your Graptophyllum Pictum. These tiny bugs can be green, gray, brown, or black and usually remain sedentary once they’ve latched onto a plant.
If the infestation isn’t extensive, you can discourage scale insects from attacking your plant by mixing in four glasses of water and a teaspoon of neem. Vigorously spray the plant with a spray bottle.
Neem oil and horticultural oils will not eradicate the bugs, but they will surely harm them. Many pesticide sprays for scales are deemed safe for use inside.
Your tropical houseplant can fall victim to a Mealybug infestation. They feed on the plant’s sap using their sucking tubes and will weaken your Joseph’s Coat.
As a prevention against many diseases, I recommend a monthly application of neem oil on your houseplants. Remember to dilute the neem and spray only during cool weather.
In the case of an infestation, take a cup of rubbing alcohol and combine it with a teaspoon of fragrance-free dish soap and water in a spray bottle. Spray that on Joseph’s Coat twice a week until the mealybugs are gone.
Brown Leaf Tips
The edges of your Caricature Plant’s leaves may turn brown if it’s not getting enough amount of moisture that it needs from the air and its roots. Water your plant on time and inspect if the humidity level in its place is consistent with its needs.
You may also need to consider the amount and frequency of applying fertilizers. Overfeeding can burn the houseplants’ foliage, typically manifesting as browning edges on their leaves.
The leaves of your Graptophyllum Pictum might start to droop if it’s not getting the proper amount of moisture and light it needs. Check out or Water and Light portions above to learn about the recommended care practices for your plant.
Low humidity can potentially cause drooping leaves, so monitor the humidity levels in your location and make sure they meet your plant’s demands.

A variety of factors might induce yellowing leaves on Justicia Picta. For starters, a lack of light might deplete your plant of nutrients and cause its leaves to become yellow. Alternatively, there might be a problem with underwatering, overwatering, an irregular watering schedule, or too much shady location.
Take out yellowing leaves so the plant can focus its energy on growing new green leaves instead.
The overabundance of water, which leads to root rot, is often fatal for Joseph’s Coat. Once decay starts, it is difficult to control. Your safest choice is to fully remove the root system and restart your plant as if you were propagating a cutting.
Of course, you can always take preventative measures to avoid root rot. First, provide your plant with a fast-draining, well-aerated soil mix. Chunky materials can be added to create air spaces and allow the roots to breathe.
Second, make sure you choose a pot for functionality, not just for aesthetics. The essential requirement for houseplants is drainage. If there are no drainage holes in your chosen pot, don’t be afraid to drill some holes!
Do not water your plant until you are certain that the soil is no longer damp after your last watering. To check for moisture, stick your finger into the soil or use the old-fashioned wooden skewer approach.
