It has a rounded to cylindrical shape, and its green, ribbed stems are covered in a profusion of spines that range in color from yellowish-brown to jet black. The stems also produce bright pink or red flowers, which bloom in late spring to early summer and are followed by edible red fruit.
Origin and Distribution
Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson is native to the southwestern United States and northern Mexico, including Arizona, New Mexico, Colorado, Utah, Texas, and Chihuahua. It is commonly found in rocky, dry habitats such as canyons, hillsides, and mesas.
Uses
The Black-spined Hedgehog Cactus has a few uses. Its fruit is edible and can be eaten raw or cooked. The fruit is also used to make jelly, syrup, and candy. However, it is important to note that the fruit can be difficult to harvest due to the dense spines covering the stems. The plant is also used as an ornamental, often grown in gardens or used in landscaping. Additionally, some Native American tribes have used the cactus for medicinal purposes, including as a treatment for headaches, fever, and stomach issues.
General Care
Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson is a relatively easy plant to care for as long as its basic needs are met. It prefers well-draining soil with plenty of sand or gravel mixed in and requires full sun to thrive. Overwatering is the biggest threat to its health, so it is best to let the soil dry out completely between waterings. During the winter, the plant goes dormant and requires minimal water.
Light Requirements
The Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson plant thrives in areas with full sun exposure. Therefore, it is recommended to place it in an open area with direct sunlight, such as a sunny windowsill or outdoors in your garden.
Temperature Requirements
This plant can tolerate cold temperatures, as low as 0 degrees Celsius, making it an ideal plant to grow outdoors in many areas. It can also tolerate high temperatures, as high as 40 degrees Celsius. However, it is important to ensure that the temperature does not stay stagnant, as that can cause harm to the plant.
Soil Requirements
The Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson plant requires well-draining, sandy soil that is rich in minerals and does not hold excess water. Additionally, the soil must be slightly acidic, with a pH range of 5.5 to 7.0. It is also important to remember that this plant grows in regions with low rainfall, so it does not require much water, and the soil should be allowed to dry out in between watering.
Cultivation methods
Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson is a cactus that thrives best in well-drained soil. For optimal growth, plant the cactus in a pot that is at least two inches larger than the width of the cactus. Make sure that the pot has drainage holes at the bottom to prevent waterlogging.
The cactus needs to be placed in an area that receives full sunlight for about six hours daily. During the growing season, which is normally spring, the cactus should be periodically rotated to ensure even exposure to sunlight.
Watering needs
When watering Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson, it is important to avoid overwatering. The cactus should be watered once the top layer of soil in the pot feels dry. During the growing season, water more frequently, about once every two weeks. Reduce watering during the dormant period, typically in winter.
The cactus should never be watered from the top, as this can cause water to collect at the base, leading to rotting. Rather, immerse the pot in a bowl of water for about 10 minutes, then remove and allow it to drain.
Fertilization
Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson should be routinely fertilized during the growing season. Fertilize every two weeks with a cactus-specific fertilizer. Alternatively, use a low-nitrogen fertilizer mixed at half strength.
Fertilize only when the cactus is actively growing, and avoid fertilizing during the dormant season.
Pruning
Pruning Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson is not required. However, as the cactus ages, it may produce offsets. These offsets can be removed from the parent plant by cutting them off at the base and allowing the cut to callus over for a day or two before potting separately.
Dead or damaged plant parts should be removed immediately to prevent the spread of diseases. Use clean, sharp pruning shears disinfected with rubbing alcohol before and after use to prevent the spread of diseases or pests.
Propagation of Echinocereus Triglochidiatus Engelm. var. Melanacanthus (Engelm.) L. Benson Plant
Echinocereus triglochidiatus Engelm. var. melanacanthus (Engelm.) L. Benson, commonly known as the black-spined hedgehog cactus, is a drought-tolerant plant native to the southwestern United States and Northern Mexico. Propagating this plant can be done through several methods.
Seed Propagation
The easiest way to propagate Echinocereus triglochidiatus is through seeds. The plant typically flowers in late spring or early summer and produces small, raspberry-like fruits. These fruits should be allowed to remain on the plant until they are fully ripe and begin to split open. Once the fruit has split, the seeds can be collected and cleaned.
Plant the seeds in well-draining soil and keep them moist until they germinate, usually within two to four weeks. The seedlings will begin to develop their spines within a few months.
Offsets
Offsets, or “pups,” are small plants that grow from the base of the mother plant. These can be carefully removed once they have developed a sizeable set of roots. The best time to separate an offset from the mother plant is in the spring when it is actively growing.
The separated offsets should be planted in a well-draining soil mix and kept in a warm, dry location until they have redeveloped their root system.
Stem Cuttings
Echinocereus triglochidiatus can also be propagated through stem cuttings. Use a sharp, clean knife to remove a segment of stem from the mother plant. The cutting should be allowed to dry for several days before it is planted in a well-draining soil mix.
The cutting should be kept in a warm, dry location until it has redeveloped its root system. Once the cutting has rooted, it can be potted in the same way as a seedling or an offset.
