Haworthia attenuata var radula

🌿✨ Haworthia attenuata var. radula — The Textured Zebra Plant
Haworthia attenuata var. radula, often referred to as the Zebra Plant or Pearl Plant, is a striking succulent known for its dense, rough-textured white tubercles (bumps) covering the green leaves, creating a more rugged appearance than the common Haworthia attenuata. Native to South Africa, this species is popular in indoor gardens due to its attractive, hardy nature and low maintenance needs.

This variety is distinguished from other Haworthias by its more pronounced, wart-like texture on the leaves, giving it a distinctive architectural look.

🌿 Botanical Overview
Scientific Name: Haworthia attenuata var. radula

Common Names: Textured Zebra Plant, Pearl Plant

Family: Asphodelaceae

Origin: South Africa

Growth Habit: Compact, rosette-forming succulent

Size:

Height: 4 to 6 inches (10–15 cm)

Width: 5 to 8 inches (12–20 cm)

USDA Hardiness Zones: 9–11

🍃 Appearance
Leaves:

Fleshy, triangular, and dark green leaves arranged in a dense rosette

Covered with distinctive, rough, white raised tubercles on both sides

Leaves are pointed, sometimes with a rougher edge than other Haworthia species

Texture is coarser compared to the smoother Haworthia fasciata

Flowers:

Produces slender flower spikes (inflorescences) with small, white tubular flowers

Blooming usually occurs in spring or summer

Flowers are modest but a pleasant bonus

This plant’s sculptural appearance and textured leaves make it a beautiful ornamental choice.

☀️ Light Requirements
Indoors:

Prefers bright, indirect sunlight

Can tolerate low-light conditions, making it ideal for homes and offices

Best placed near an east or west-facing window

Outdoors:

Thrives in partial shade or filtered sunlight

Avoid direct, harsh afternoon sun, which can cause leaf burn

If grown under insufficient light, the plant may stretch or lose its compact form.

🌡️ Temperature & Humidity
Temperature:

Optimal range: 18–27°C (65–80°F)

Avoid temperatures below 5°C (41°F) — not frost-hardy

Bring indoors in colder climates during winter

Humidity:

Prefers low to moderate humidity

Well-suited to indoor environments with dry air

Ensure good airflow to prevent fungal growth

💧 Watering Routine
Growing Season (Spring to Fall):

Water when the top 1–2 inches of soil are dry

Typically every 10 to 14 days, depending on environment

Water thoroughly and allow excess water to drain completely

Winter Dormancy:

Reduce watering to about once every 3–4 weeks

Allow soil to remain mostly dry to avoid rot

🚫 Key Rule: Avoid letting water sit in the leaf rosette or around the roots, as this can cause rot.

🌱 Soil Requirements
Type:

Requires well-draining soil

Recommended mix:

50% cactus/succulent mix

25% coarse sand

25% perlite or pumice

pH: Neutral to slightly acidic (6.0–7.0)

Proper drainage is crucial for maintaining healthy roots and preventing moisture-related diseases.

🌾 Fertilizing
During Growing Season:

Feed once a month with a diluted balanced succulent fertilizer

Use low-nitrogen formulas like 5-10-10 NPK

Winter:

Do not fertilize, as the plant enters dormancy

Over-fertilizing can weaken the plant and lead to soft, leggy growth.

✂️ Maintenance and Pruning
Pruning:

Remove dried or damaged leaves with clean scissors

Clear debris from the base to prevent pests

Pests:

Occasionally susceptible to:

Mealybugs

Spider mites

Scale insects

Treat with neem oil or insecticidal soap

🌿 Propagation
Offsets (Pups):

The most common method

Gently remove pups that grow at the plant’s base once they are at least 1/3 the size of the mother plant

Allow offsets to callous for a day before planting in dry, well-draining soil

Leaf Cuttings:

Less reliable but possible

Let leaf cuttings callous before planting

Seeds:

Possible but very slow and uncommon for casual gardeners

🛡️ Common Issues
Overwatering: Root rot is the biggest risk

Sunburn: Leaves turn pale, yellow, or scorched in too much direct sun

Etiolation: Stretching occurs if the plant doesn’t get enough light

Pests: Dusty, poorly ventilated spaces can attract insects

🎍 Decorative & Practical Uses
Perfect for:

Succulent arrangements

Rock gardens

Indoor pots on desks and shelves

Terrariums with ventilation

Its compact, rough-textured form makes it a standout in minimalist and modern decor.
