Graptopetalum pentandrum aka Five Stamen Graptopetalum

Taxonomy ID: 8934

Graptopetalum pentandrum, commonly known as Five-stamen Graptopetalum, is a stunning succulent shrublet native to the rocky cliffs of Michoacán, Mexico, where it grows at elevations around 3,940 feet (1,200 m). First described by Reid Moran in 1971, with the first wild population discovered by Alfred B. Lau in May 1973 near El Salto waterfall, this species has become a popular ornamental succulent.

The plant forms attractive rosettes of fleshy, triangular leaves at the ends of woody, branching stems. The stems are initially erect but may become slightly decumbent with age, reaching up to 6 inches (15 cm) in length. The rosettes typically measure up to 3.2-5 inches (8-12.5 cm) in diameter and display a captivating color palette: leaves emerge bluish-green before maturing to yellowish-grey, often with a distinctive lavender hue. The foliage is covered in a powdery layer of farina (epicuticular wax), giving the plant a soft, frosted appearance.

The specific epithet 'pentandrum' means 'five stamens' and refers to a unique botanical feature—unlike other Graptopetalum species that typically have ten stamens, this species has only five. The flowers appear in slightly branched inflorescences from late winter to early spring, displaying star-shaped blooms of pale yellow or yellowish-white petals adorned with dark red markings and red stamens, creating an elegant contrast against the glaucous foliage.

In cultivation, Graptopetalum pentandrum is valued for its relatively compact growth habit, attractive year-round foliage color, and ease of care. The subspecies superbum (often treated as a separate species, Graptopetalum superbum) is particularly popular, featuring denser rosettes and more pronounced lavender coloring. While typical plants reach 8 inches (20 cm) in height, mature specimens in ideal conditions can grow significantly larger. The plant branches readily from the base, creating attractive multi-stemmed clumps that spread 12-18 inches (30-45 cm) wide.

This succulent is well-suited to container cultivation as a houseplant and thrives in rock gardens, succulent arrangements, and xeriscaping in warmer climates (USDA zones 9b-11b). Its low-maintenance requirements, drought tolerance, and non-toxic nature make it an excellent choice for beginners and experienced succulent enthusiasts alike.

More information about Five Stamen Graptopetalum

How difficult is it to care for Graptopetalum pentandrum?

Graptopetalum pentandrum is an easy-care succulent that's excellent for beginners. It tolerates neglect well, is highly drought-resistant, and forgives typical beginner mistakes like occasional missed waterings. The main care requirement is avoiding overwatering, as this succulent is vulnerable to root rot if kept too moist.

What temperature does Graptopetalum pentandrum need?

This succulent prefers warm conditions with daytime temperatures of 65-75°F (18-24°C) and nighttime temperatures of 50-55°F (10-13°C), mimicking its native Mexican habitat. It can tolerate temperatures as low as 25°F (-3.9°C) briefly, but thrives best when kept between 59-80°F (15-27°C). Protect from frost and freezing temperatures for extended periods.

How do you propagate Graptopetalum pentandrum?

Graptopetalum pentandrum propagates easily through leaf cuttings, stem cuttings, or offsets—even fallen leaves will often root spontaneously. For leaf cuttings, allow the leaf to callous for a few days, then place on well-draining soil. For offsets, gently separate rosettes with roots attached, let callous, then plant in succulent mix. Stem cuttings should be placed in soil with at least one node buried, given bright indirect light, and watered minimally until roots establish.

When and how does Graptopetalum pentandrum flower?

🌸 Late winter to early spring

Graptopetalum pentandrum blooms in late winter to early spring, producing slightly branched inflorescences with star-shaped flowers. The blooms are yellowish-white to pale yellow with distinctive dark red markings and red stamens. A unique feature is that flowers have only five stamens (hence the name 'pentandrum'), unlike other Graptopetalum species which typically have ten stamens.

When should I repot Graptopetalum pentandrum?

Repot every 1-2 years or when the plant doubles in size, whichever comes first. This slow-growing succulent doesn't require frequent repotting unless root-bound. When repotting is needed, choose a container only 1-2 inches (3-5 cm) larger in diameter than the current pot. If roots aren't crowded, you can simply refresh the soil in the same container rather than sizing up.

What pests and diseases affect Graptopetalum pentandrum?

Common pests include aphids, mealybugs, and spider mites, which can stress the plant and increase disease susceptibility. For aphids, use a strong stream of water or introduce natural predators like ladybugs. Treat mealybugs with insecticidal soap or dab with rubbing alcohol on a cotton swab. The main disease concern is root rot from overwatering. Regular inspection, especially of leaf undersides and stem junctions, combined with proper watering and light, helps prevent most problems.

Does Graptopetalum pentandrum need pruning?

Minimal pruning is needed for Graptopetalum pentandrum. Remove dead or damaged leaves by gently pulling them from the base to maintain appearance and prevent pest harboring. If the plant becomes leggy from insufficient light, you can trim back stems to encourage branching. Pruning is best done in the active growing season (spring-summer), and stem cuttings can be used for propagation.

How should I clean Graptopetalum pentandrum leaves?

Be gentle when cleaning Graptopetalum pentandrum as the leaves are covered with a protective powdery coating called farina (epicuticular wax) that gives them their frosted appearance. Avoid touching or wiping the leaves as this removes the farina permanently. Instead, use a soft brush or gentle air flow to remove dust. The farina provides sun protection and helps reduce water loss, so preserving it is important for plant health.

Why are my Graptopetalum pentandrum leaves turning yellow?

Yellowing leaves in Graptopetalum pentandrum most commonly indicate overwatering or poor drainage leading to root problems. Ensure the soil dries completely between waterings and that your pot has drainage holes. Other causes include normal aging (lower leaves naturally yellow and drop), insufficient light, or nutrient deficiency. Adjust watering first, as this is the most common culprit for succulents.

What causes brown leaves on Graptopetalum pentandrum?

Brown tips or edges usually indicate underwatering or low humidity, though this drought-tolerant plant rarely suffers from too little water. Brown spots can signal sunburn from sudden exposure to intense direct light—acclimate gradually if moving outdoors. Brown, mushy leaves indicate overwatering and possible rot; reduce watering immediately and ensure excellent drainage. Dry, crispy brown leaves at the base are normal aging.

Why is my Graptopetalum pentandrum growing slowly?

Graptopetalum pentandrum is naturally a slow-growing succulent, typically adding only 2-4 inches per year under optimal conditions and taking 2-3 years to reach mature size. However, insufficient light is the most common cause of even slower growth—ensure the plant receives 6-8 hours of bright light daily. Growth also slows naturally in winter when the plant enters dormancy, which is completely normal.

Can Graptopetalum pentandrum be grown outdoors?

🇺🇸 USDA 9b-11b

Graptopetalum pentandrum can be grown outdoors year-round in USDA hardiness zones 9b-11b where temperatures don't drop below 25°F (-3.9°C) for extended periods. It's excellent for rock gardens, xeriscaping, and succulent arrangements in Mediterranean and warm climates. In cooler zones, grow in containers and bring indoors before first frost. Outdoors, plant in well-draining soil in full sun to partial shade (south or west-facing positions are ideal).

How big does Graptopetalum pentandrum get and how fast does it grow?

Slow

Graptopetalum pentandrum is a slow-growing, compact succulent that typically reaches 8 inches (20 cm) in height with a spread of 12-18 inches (30-45 cm) at maturity. Individual rosettes grow 3-5 inches (8-12.5 cm) in diameter. The plant branches from the base, creating attractive multi-stemmed clumps. Growth is slow to moderate, with plants adding only 2-4 inches annually under optimal conditions and taking 2-3 years to reach full size. In full sun, plants tend to stay smaller and more compact.

Where is Graptopetalum pentandrum native to?

Graptopetalum pentandrum is native to Mexico, specifically the state of Michoacán, where it grows on shady rock cliffs at elevations around 3,940 feet (1,200 m). The first wild population was discovered by botanist Alfred B. Lau in May 1973 at El Salto, a waterfall located 4 km north of Aguililla. The species was originally described by Reid Moran in 1971.

Are there different varieties of Graptopetalum pentandrum?

The most commonly cultivated variety is Graptopetalum pentandrum subsp. superbum (often sold as Graptopetalum superbum or 'Beautiful Graptopetalum'), which features denser, flatter rosettes with more pronounced lavender-pink coloring and thicker stems compared to the species. A variegated form, Graptopetalum superbum 'Variegatum', exists with cream and pink striped foliage. Note that recent taxonomic work has reclassified these plants under the genus Quetzalcoatlia, though they're still widely sold under the Graptopetalum name.

How does care for Graptopetalum pentandrum change by season?

During spring and summer (active growing season), water regularly when soil dries completely, fertilize every 3-4 months with succulent-specific fertilizer, and provide 6-8 hours of bright light daily. In fall and winter (dormancy period), reduce watering significantly—allow soil to stay dry for extended periods and only water sparingly to prevent complete dehydration. Stop fertilizing in winter. Growth naturally slows during dormancy, which is normal and healthy. Maintain temperatures above 25°F (-3.9°C) year-round.
