Haworthia Retusa Gravel

Haworthia Retusa is a beautiful and unique succulent that’s perfect for any home.

Haworthia Retusa refers to succulent plants in the Asphodelaceae family hailing from South Africa. It is a member of this family native to Riversdale in the Western Cape Province in South Africa. This small, perennial succulent is known by many other names, including Star Cactus, Cushion Aloe, Window succulent, and Aloe retusa.

The name Haworthia honors the British botanist Adrian Haworth. Retusa is a Latin term used to denote the ‘retused’ shape of the leaves.

Plant Characteristics.

Haworthia retusa is recognized by the characteristics of the leaves, which are distinct. The leaves are triangular and display a thick cushion-like body., often with lines. In addition, they have translucent epidermal windows on the tops of the leaves. Some give it the name Star Cactus due to the shape of the rosettes of fleshy leaves.


The plant is 3-4 inches tall and the same in width. Flowers can be seen in late spring or the beginning of summer on a stem that can grow up to 20 inches in height. Tiny, white tubular flowers adorn the top of the stem. 

At the base of the plant, the root is thick and woody and can carry a group of plants. Haworthia retusa can withstand harsh conditions, and in their natural habitat, mostly lower hills and flatter terrain, they are commonly found buried in the sand.

Only the top of the rosette can be seen above ground in an eye-catching bright green. Bright sunlight brings out the best color in the leaves.

Propagation of Haworthia retusa.

Gardeners love this plant. They are easy to grow as long as the conditions are right. The best way to propagate the plant is by planting offsets. Other options include leaf or stem cuttings, as usually done with succulents.

A clean, sharp knife is used to pry away the offset from the mother plant. After carefully trimming the baby plant, it can safely be transplanted into the sandy soil mix. The baby plants should be laid out to dry overnight before introducing to their pots. After planting, the pots should be placed in a sunny, warm spot. 

New plants do require watering. The soil has to be allowed to dry out before watering again. The next option is to propagate Haworthia retusa from leaf cuttings. The leaves are cut close to the stem. Allow them to dry overnight, and then plant in potting mix that drains well. A rooting hormone is a good idea at this point. Once planted, the pots can be placed in indirect sunlight. 

Haworthias can successfully be grown from seeds. However, sourcing seeds might prove difficult as only specialist dealers of succulents might carry them. These seeds are grown in moist soil and germinate for around a week or two. During this period, the soil must be kept moist.
