What are Haworthia Succulent Plants?
Haworthia is one of the largest genera of succulents. Most of the species belonging to this genus are native to the South African region.
Two of the most common haworthia plants are the Haworthia fasciata and the Haworthia attenuatais. Both look very similar but have slight differences.
However, they are both commonly known as Zebra Plant, Zebra Haworthia, or Zebra cactus – even though they are succulents, not cactus plants.
The leaves have similar appearances to aloe plants, but they have beautiful white stripes that aloe plants do not have.
Haworthia succulents are impressive and little in shape. Thus, people prefer having them as houseplants.
People living in the summer region keep these succulents indoors or plant them in the garden, while in a cold region, these plants should be kept indoors.

Types of Haworthia Succulents to Grow
In the Haworthia genus, there are more than a hundred species, and their classification is quite complicated.
The core differences among the species are the size and the orientation of white stripes displayed on the leaves.
We suggest you buy the variety that seems the most attractive to you.
Here, we will mention some of the easiest and best-looking Haworthia to grow as your garden plants.

Even if you do not place it there, it will grow happily. This is why these varieties are so popular among gardeners.
These Haworthia succulents require sandy soils with excellent drainage to grow. You may use perlite or pumice in the mixture to enhance the drainage system.
These plants are not heavy drinkers. They can survive in drought conditions pretty well.
Haworthia fasciata plants are usually small. The leaves have a triangular shape with beautiful dark green colors and white stripes.
This flowering plant produces its flowers from October to November.
Many people often confuse it with Haworthia attenuata, which is also grown as an indoor plant.
Haworthia attenuata has more rough-edged leaves, while Haworthia fasciata has stouter leaves and tends to have an inward curvature.
Haworthia fasciata is a rare species. You may easily distinguish it if you have sufficient knowledge about the colors and patterns.
However, both plants are considered Zebra Plants, Zebra Haworthia or Zebra cactus, although they are not cactus plants, rather succulents.

Haworthia Cooperi Var. Picturata
Haworthia cooperi var. picturata is a fascinating succulent, which is stemless. It seems attractive mainly due to its vigorous, large clumps.
This variety of H. cooperi is not so challenging to grow. If you can keep an aloe plant alive, then you will also maintain this variety.

Haworthia Plant Care and Requirements
Haworthia plants are small, slow-growing, and one of the hardest plants to kill. They form beautiful rosettes of fleshy leaves, which have white pearly bands.
This design gives them a unique appearance. You may purchase them as potted plants from the garden store.
Also, try to plant them in the early Spring or Summer.
Like other succulent plants, Haworthias are extremely easy to grow. You do not have to worry about their maintenance, which is not so required.
Make sure that you are supplying them with adequate sunlight and moisture. In terms of fertilizing, always fertilize them in spring, when they grow actively.
Let’s take a look at their major requirements.
The species belonging to the Haworthia genus prefer bright light. It is okay if you provide them with direct sunlight for a few hours.
In their native areas, you will find them mainly growing in shady spots.
They can withstand the morning sun, but solid and intense light may burn the foliage in the noon.
White, yellow, or red leaves indicate too much sun. If you notice faded colors, move the plants to sunny areas.
While growing outdoors, gardeners can place them in sheltered areas instead of full sun.
If you have pots, then it is better to put them in the west-facing window to receive bright indirect light.
Like other succulents, Haworthia is best grown in well-drained soils.
Before you plant them in a container, make sure that the potting mix is not clayey because clay soil has poor drainage.
Mix gravels, perlite, pumice, sand, coco peat, and other organic materials to prepare fresh soil with an enhanced drainage system.
You may also use cactus potting mix for container plants. Make drainage holes if the container does not have them.
Excess soil moisture can cause root rot and death to your stunning Haworthia plants. Rinse them when the topsoil seems dry.
During the summer months, water them once every week while reducing the frequency of watering in winter.
Avoid overwatering Haworthia species.
Temperature and Humidity
Haworthia plants grow best in warm and dry conditions. The temperatures should be between 70- and 95-degrees Fahrenheit.
They can tolerate as low as 50-degrees F in Winter. However, beware of the frost as these species may suffer from freezing injury.
Moderate humidity is fine, though it is not required. They prefer growing in dry climates.
The fertilizer requirements of Haworthia are similar to other cactus species. They grow slowly.
That’s why we suggest you fertilize them during Spring and Summer. Over-fertilization causes leaf burn.
