Origin and Common Names
Ophthalmophyllum rufescens (N.E.Br.) Tischer is a succulent plant species belonging to the family Aizoaceae. It was first described by N.E. Brown and named as Mesembryanthemum rufescens in 1922, and was later reclassified and given its current name in 1931 by Johannes Arnold Tischer. The plant is commonly known as the "Red Window Plant" or "Red Eyed Window Plant."
General Appearance
The Ophthalmophyllum rufescens grows up to about 3 inches in height and 8 inches in diameter. It has a clumping, mat-forming growth habit, and the leaves are arranged in a rosette pattern. The leaves are small, approximately 10 mm in length, and are clustered on short stems. The color of the leaves is typically blue-green with reddish margins, and they are covered in tiny, translucent bumps known as "fenestrations." These fenestrations allow light to pass through the leaves and reach the plant's interior, making it appear as though the plant has small, "window-like" holes.
The flowers of the Ophthalmophyllum rufescens are small and white, and tend to bloom in late winter to early spring. The flowers are borne on short stems that arise from the center of the plant, and they open during daylight hours before closing at night.
Uses
The Ophthalmophyllum rufescens is primarily grown as an ornamental plant, and is well suited for use in rock gardens, containers, and as a ground-cover plant. Its unique appearance, particularly the translucent "windows" on its leaves, make it a popular choice for gardeners and collectors of succulent plants.
While the plant is not typically used for medicinal or culinary purposes, some cultures believe that succulent plants such as Ophthalmophyllum rufescens have spiritual and healing properties. They may be used in rituals or as part of traditional medicine practices.

Fertilizer:
Ophthalmophyllum rufescens does not need regular fertilization. However, to promote growth and flowering, it is recommended to use a balanced fertilizer once a month during the growing season.
Propagation:
Ophthalmophyllum rufescens can be propagated by stem cuttings or seeds. Stem cuttings should be allowed to dry for a few days before being planted in well-draining soil. Seeds can be planted in the same type of soil and should be kept moist until they germinate.
Cultivation of Ophthalmophyllum rufescens
Ophthalmophyllum rufescens is a succulent plant that requires well-draining soil and good air circulation. It can be grown in pots or in rock gardens, and in areas with mild winters, it can also be grown outdoors.
When planting in a pot, use a mix of cacti and succulent soil with added perlite or sand to increase drainage. In a rock garden, plant in a well-draining soil mix and add rocks and gravel to aid in drainage.
Watering Needs of Ophthalmophyllum rufescens
Ophthalmophyllum rufescens is drought-tolerant and does not require frequent watering. Water only when the soil has completely dried out, and be sure not to overwater as this can lead to root rot. During the growing season, water once a week, and reduce watering in the winter months when the plant is dormant.
Fertilizing Ophthalmophyllum rufescens
Fertilize sparingly with a cactus or succulent fertilizer during the growing season. Apply the fertilizer once a month and ensure that the soil is moist before fertilizing.
Pruning Ophthalmophyllum rufescens
Pruning is not necessary for Ophthalmophyllum rufescens, but if the plant becomes too leggy, you can prune the stem to encourage branching. Take care when pruning to avoid damaging the leaves.
Propagation of Ophthalmophyllum Rufescens
Ophthalmophyllum rufescens (N.E.Br.) Tischer is a succulent species of the family Aizoaceae, which is native to South Africa. It is commonly known as "Red Ophthalmophyllum" or "Red Jewel." This plant species is an excellent choice for succulent lovers who want to propagate new plants from their existing collection. There are different methods of propagating Ophthalmophyllum rufescens; here are some of the most commonly used methods:
Offsets
Offsets or "pups" are small, baby plants that grow around the base of the parent plant. These offsets can be easily separated from the parent plant and potted up independently.
To propagate Ophthalmophyllum rufescens from offsets:
- Remove the baby plant from the parent plant by gently pulling it away.
- Allow the offset to dry for a day or two.
- Once the cut has dried, pot it up in a well-draining mix for cacti and succulents.
- Water the newly potted plant, then wait for the soil to dry out before watering again.
Leaf Cuttings
In addition to propagating via offsets, Ophthalmophyllum rufescens can also be propagated using leaf cuttings. This method is suitable for propagating plants with damaged stems or for those who want to grow many plants from one.
To propagate Ophthalmophyllum rufescens from leaf cuttings:
- Cut a healthy leaf from the parent plant using a sharp, sterilized knife or pruner.
- Allow the cut to dry and callous over for a few days to prevent rotting during the rooting process.
- Once the cut has calloused, plant the leaf cuttings in a well-draining mix for cacti and succulents.
- Water the newly potted plant lightly, then wait for the soil to dry out completely before watering again.
- After a few weeks, new plants should begin to grow from the base of the leaf cuttings.
Propagation via offsets and leaf cuttings are the two most commonly used methods of propagating Ophthalmophyllum rufescens. Follow these tips to ensure successful propagation of your Red Jewel succulent plants.
