Origin and description

graptopetalum pentandrum

The plant originates from the Eastern Sierra Madre Occidental region of Mexico, where it grows in wet cliff faces and rocks. It is a perennial plant that starts blooming in late spring or early summer and can continue to flower until fall. It grows from 15 cm up to 20 cm tall, with thin stems often lying on the ground. The leaves are shaped like maple leaves, they start out as an emerald green color but turn a bright, metallic yellow as the plant begins to bloom.

The flower is not very remarkable and it can be easily missed: they are star-shaped with five lavender petals and ten protruding stamens that look like antennae. The flowers droop downwards from their curling stems due to heavy pollen production. They have an unpleasant scent that can attract flies as pollinators.

Graptopetalum pentandrum propagation

Propagation can be done by seed or stem cuttings. The seeds are enclosed in a papery envelope that must be removed before planting them. They should be planted on well-draining soil and watered frequently until they germinate.

Stem cuttings are best harvested at the end of summer when the plant starts to die. The cuttings should be relatively new and healthy, with a length of at least 15 cm. They should then be allowed to dry out for one or two days before planting them in well-draining soil. As they continue to grow, the plants will form an extensive root system that can help protect against erosion and harsh winds due to their strong, downward-facing flowers.

It is recommended by some sources that this plant should be grown in part shade, with lots of water. It cannot survive temperatures below 0°C and it needs to have a lot of oxygen around the roots so it can grow well on rocks or walls. The leaves are very sensitive to cold airflow, which makes them curl completely up when exposed to wind and low outdoor temperatures.

This plant does not need fertilizing, but if it is provided with some nutrients, the blooming time will be extended by a few weeks. It can also be propagated from seed or cuttings while in bloom to preserve its flowers for an even longer period of time.

Graptopetalum pentandrum care

Graptopetalum pentandrum is easy to care for. They appreciate cooler growing conditions. They like to be kept in an area where temperatures stay around 65 degrees Fahrenheit during the day and 55 degrees at night. While they don’t mind bright light, it is important not to allow them to dry out between watering or their leaves will fade away quickly.

Light requirements

Graptopetalum pentandrum is a low-maintenance plant. It tolerates most lighting conditions, including direct sunlight and fluorescent light. They can even grow outdoors in full sun or partial shade as long as the soil remains dry to minimize evaporation.

Graptopetalum pentandrum also thrives in medium light. If the plant is kept too dark, it may stretch out and fail to bloom.

Soil/potting mix

Graptopetalum pentandrum grows well in a cactus mix, or it can be grown exclusively in pumice. If you are growing the plant for its flowers, consider adding limestone to your potting mix at one-eighth of the total volume. This will increase calcium uptake and benefit blossom quality.

Watering

Graptopetalum pentandrum has high drought tolerance. If the plant is grown in the cactus mix, it will need water only once every two weeks during spring and summer. When growing outdoors, watering twice per month should be sufficient to keep the plant thriving year-round.

If you are growing the plant indoors, water every one to two weeks. When watering, apply enough liquid so that about half of the soil mix is thoroughly moistened. Allow the top centimeter or so to dry out before watering again.

Fertilizer

Graptopetalum pentandrum can be fertilized every other month. Use a balanced cactus fertilizer and apply it at one-quarter the recommended strength, or follow the instructions on your particular product packaging for correct dosage information.

If you are growing graptopetalum pentandrum in pumice, then once every three months should be sufficient. If you are growing the plant in cactus mix, the plant will benefit from diluted foliar feeding every two weeks using a water-soluble 20-20-20 NPK fertilizer.

Do not feed your plant during winter time when it is dormant or if there is no new growth.

Temperature

Graptopetalum pentandrum grows well with a minimum temperature of 15°C and a maximum temperature of 25°C. It can tolerate brief dips below freezing, but otherwise, it is not cold-hardy.

The ideal range for graptopetalum pentandrum is between 12°C and 20°C.

Humidity

Graptopetalum pentandrum does not require high humidity. It will grow well with a relative humidity of around 50%.

Pruning

Pruning is not required for graptopetalum pentandrum. If you wish to prune the plant, do so after it has finished blooming in late autumn or wintertime.

You can remove dead leaves and stems at any time of year without causing harm to the plant.

When to repot

Graptopetalum pentandrum should be repotted every other year in order to refresh the potting soil and provide a clean container for optimal health.

The best time of year to transplant this plant is during autumn or early springtime before new growth begins. Repot using pumice mixed with organic soil or cactus mix.

If you are growing graptopetalum pentandrum in a hanging pot, it may outgrow its container within three to four years and need transplanting into a larger one. Ensure that there is adequate drainage at the bottom of the new potted plant before replanting it outdoors or indoors as needed.

Do not use fertilizer when transplanting as it may burn the roots and cause damage.

Dormancy

Graptopetalum pentandrum is not dormant and can survive year-round outdoors in mild climates or if protected from frost during wintertime.

If you live in a region with mild winters, graptopetalum pentandrum can remain outdoors all year round as long as it is protected from winter frost. If you plan on overwintering your plant indoors, or if temperatures in your area drop below freezing, keep it in a cool room with bright light.

If you plan to overwinter your plant indoors, move it to a cold greenhouse before the first frost and bring it back inside when new growth begins in early springtime. If you live where winters are harsh or plants may freeze outdoors, protect your plant with a sheet when the temperature drops below freezing.
