Cylindropuntia echinocarpa, also known as the Silver Cholla or Golden Cholla, is a species of cactus native to the United States and northwestern Mexico. It is closely related to many other well-known cacti, such as the prickly pear and the saguaro.
The Silver Cholla is a unique and fascinating plant with a distinctive appearance and several interesting characteristics.
This article will introduce you to this fascinating species and provide an overview of its natural history and ecology. We will also discuss some challenges facing the Silver Cholla in the wild and how conservation efforts are working to protect this important plant.

About Cylindropuntia echinocarpa
The Silver Cholla cactus is a plant native to the southwestern United States. These trees grow in sandy soils and are used by many people for landscaping purposes. The Silver Cholla has white or yellow spines arranged neatly on the stems and greenish-yellow flowers up to 1 in across. The fruits are spiny and greenish-brown with white seeds.
A variation of this cactus is called the Golden Cholla, which has golden spines instead of white or yellow ones. This cactus can grow up to 10 feet tall and 5 feet wide, but they usually stay smaller in cultivation.

Silver Cholla Care
The Silver Cholla is not a particularly difficult plant to care for, but it does have some specific requirements that must be met in order to thrive. This species is generally best suited for experienced cactus enthusiasts rather than beginners.
Like many cacti, the Silver Cholla prefers bright, direct sunlight. It should be placed in a location where it can receive at least a couple of hours of full sun per day. However, it is important to avoid exposing the plant to intense heat, as this can cause it to become sunburned or suffer from other stress-related issues.
It grows best in sandy, well-draining soils that are relatively low in organic matter. A well-draining cactus mix typically contains a combination of sand, perlite, and other materials that help to improve drainage and aeration.
The correct soil choice is important for these cacti, as they are susceptible to root rot if they remain too wet for extended periods.
The Silver Cholla should be watered deeply but infrequently. This means allowing the soil to dry out completely and providing the plant with a thorough watering when needed. Overwatering can be a common problem with cacti, as it can lead to root rot and other issues.
Reduce watering in winter.
The Silver Cholla generally prefers temperatures between 50 and 85 degrees Fahrenheit. It can tolerate temperatures outside this range, but it is important to avoid exposing the plant to extreme heat or cold. In particularly hot or cold environments, it may be necessary to provide some additional protection for the plant, such as a shading cloth or a protective covering.
It prefers very low levels of humidity and appreciates dry, arid conditions.
The Silver Cholla should only be fertilized occasionally, and it is best to use a cactus-specific fertilizer. Overfertilizing can lead to excessive growth and other problems, and it is important to avoid this in order to ensure the plant’s health.
The Silver Cholla is most receptive to fertilizer during the active growing season.
The Silver Cholla should only be pruned when necessary. This might include removing dead or damaged branches or trimming back overly long or unruly growth. However, it is important to avoid pruning the plant excessively, as this can harm the plant and compromise its health.
Potting and Repotting Silver Cholla
The Silver Cholla should only be repotted when necessary. This might include repotting the cactus into a larger container if it has outgrown its current pot or repotting it into fresh soil if the old soil has become depleted or otherwise unsuitable.
How to Repot (Step-by-Step)
- Carefully remove the Silver Cholla from its current pot. Gently grasp the base of the plant and tilt it to one side, allowing the soil to loosen and the root ball to become exposed.
- Fill the new pot with well-draining cactus mix soil, and create a small depression in the center of the soil.
- Place the Silver Cholla in the pot, ensuring the base of the cactus is level with the soil surface and the plant is secure.
- Place the repotted Silver Cholla in its new location. It should receive bright, indirect light.
Propagating Cylindropuntia echinocarpa (Step-by-Step)
The Silver Cholla can be propagated through stem cuttings, a relatively simple process. To propagate a Cylindropuntia echinocarpa using stem cuttings, follow these steps:
- Choose a healthy and relatively mature stem, and avoid selecting one that is overly woody or damaged.
- Carefully remove a stem from the Silver Cholla plant, using a sharp knife or scissors to cut it away from the main plant.
- If desired, dip the cut end of the stem cutting into the rooting hormone.
- Fill a small pot with well-draining cactus mix soil, and place the stem cutting in the pot.
- Gently firm the soil around the stem cutting.
- Place the potted stem cutting in its new location, ensuring it receives bright, indirect light.
The Silver Cholla is a plant that produces small, vibrant flowers that are typically white, yellow, or pink in color. These flowers are typically produced during the warmer months of the year, typically in the spring or summer.
The Silver Cholla is not toxic to dogs, cats, or horses. However, the plant’s sharp spines can cause injury if a pet comes into contact with them, so it is important to keep the cactus out of reach of pets and other animals.
NOTE: This page is not intended as a substitute for veterinary advice. The toxicity of an ingested substance varies depending on the amount ingested, the animal’s weight, and its sensitivity to specific allergens. Contact your veterinarian or local animal poison control center immediately if you think your pet may have ingested a toxic substance.
Some common pests affecting the Silver Cholla include mealybugs, aphids, and spider mites. These pests are small insects that feed on the plant’s tissues, causing damage and potentially harming the plant’s health. In general, these pests can be treated with insecticidal soap or a similar product, and regular plant inspection can help detect infestations before they become too severe.
To prevent pests from attacking the Silver Cholla, it is important to provide the cactus with the right growing conditions. This includes providing the plant with bright, direct sunlight, using a well-draining cactus mix soil, watering the plant deeply and infrequently, and avoiding overfertilizing.
- Placing under harsh sunlight
- Using poorly drained potting mediums
- Fertilizing during dormancy
