Origin
Opuntia ×viridiflora Britt. & Rose (pro sp.), commonly known as the Mission prickly pear, is a hybrid cactus plant that originates from the southwestern United States, Mexico, and Central America. It is believed to have arisen from the natural hybridization of two species, namely Opuntia acanthocarpa and Opuntia phaeacantha.
Common Names
The Mission prickly pear is also commonly referred to as the Brown-spined prickly pear, Tulare jointfir cactus, and the Desert prickly pear. The plant derives its name from the Spanish missionaries who are said to have brought it to California in the late 1700s.
Uses
The Mission prickly pear has significant economic and cultural importance in the southwestern United States and Mexico. The plant's fruit, commonly known as "tunas," is a rich source of vitamins, minerals, and antioxidants and is used to make jam, jelly, syrup, and other products. The pads of the plant, known as "nopales," are edible and are a popular ingredient in traditional Mexican cuisine. The plant is also used for medicinal purposes, with evidence suggesting that it has anti-inflammatory, antiviral, and antimicrobial properties.
General Appearance
The Mission prickly pear is a shrubby, sprawling cactus that can grow up to 2 meters in height and 3 meters in width. It has flattened, fleshy pads that are green to blue-green in color and covered with clusters of golden-brown spines. The plant produces vibrant yellow flowers and red, purple, or green fruits that are covered with small spines. The plant is adapted to grow in arid and semi-arid regions and can withstand extreme temperatures and long periods of drought.
Light Requirements
Opuntia ×viridiflora is a cactus plant that thrives in full sunlight exposure. The plant can tolerate partial sunlight exposure, but it is recommended that the plant be kept in an area where it gets at least six hours of direct sunlight per day.
Temperature Requirements
The plant can grow in a range of temperatures between 50°F (10°C) to 90°F (32°C). However, it is better to keep the plant in temperatures between 70°F (21°C) to 85°F (29°C). The plant can withstand light frost, but it is preferable to bring it indoors if the temperature drops below 50°F (10°C).
Soil Requirements
Opuntia ×viridiflora requires well-draining soil with good aeration. The plant prefers a sandy or loamy soil that is slightly acidic with a pH level between 6.0 to 7.5. Additionally, the soil should be rich in organic matter and nutrients. It is best to avoid soil mixes that contain high levels of peat moss.
Cultivation Methods:
The Opuntia ×viridiflora Britt. & Rose is a drought-tolerant plant that thrives well in a hot and dry environment. It is easy to grow and maintain, making it an ideal plant for beginners. The plant prefers well-draining soil, and it is best to plant it in a location that receives plenty of sunlight.
Propagation of the plant can be carried out through cuttings or seeds. A cutting will start growing roots in a matter of weeks, and the new plant will start taking shape within a month. If planting from seeds, it is best to plant them in the early spring to give them ample time to establish before the winter.
Watering Needs:
Opuntia ×viridiflora Britt. & Rose is a succulent plant that stores water in its pads. This plant does not require frequent watering, and overwatering can cause root rot. A general rule of thumb is to water the plant only when the soil feels completely dry. During the winter months, reduce the watering schedule further to prevent the soil from getting waterlogged.
Fertilization:
Opuntia ×viridiflora Britt. & Rose does not require regular fertilization to thrive. However, if you notice that the plant is growing at a slow rate, it may need some fertilization to give it a boost. Use a balanced fertilizer with an NPK ratio of 10-10-10, and dilute it to half-strength before using it. Fertilize the plant once a month during the growing season. Avoid fertilizing during winter as the plant goes into dormancy.
Pruning:
Opuntia ×viridiflora Britt. & Rose does not require frequent pruning. The plant naturally grows in a clumping pattern, and these clumps can be separated and re-planted to propagate new plants. If you notice any dead or diseased pads, cut them off immediately to prevent the disease from spreading to the entire plant. Also, prune away any pads that have grown out of control to keep the plant in its desired shape.
Propagation of Opuntia ×viridiflora Britt. & Rose
Opuntia ×viridiflora Britt. & Rose can be propagated through various methods such as seeds, stem cutting, and grafting.
Seeds
The seeds of Opuntia ×viridiflora Britt. & Rose can be collected from ripe fruits. After collecting, the seeds can be cleaned, dried, and stored in a cool and dry place. They can be sown in a well-draining potting mix and kept in a warm and bright location. The seeds will germinate within two to four weeks with regular watering.
Stem cutting
Stem cuttings can be taken from healthy and mature Opuntia ×viridiflora Britt. & Rose plants. The cuttings should be allowed to dry for a day and then planted in a well-draining soil mix. They should be kept in a warm and bright location and watered regularly until root and shoot formation occur.
Grafting
Grafting is a method of propagation in which a cutting or scion of Opuntia ×viridiflora Britt. & Rose is joined to the rootstock of another plant. This method is commonly used to propagate cacti as it allows for the combination of desirable traits. The rootstock should be healthy and disease-free, and the cutting or scion should be taken from an established plant that has similar growth habits and characteristics. The two parts should be joined together with a grafting clip or tape and kept in a warm and bright location until grafting takes place.
Disease and Pest Management for Opuntia ×viridiflora Britt. & Rose (pro sp.)
Opuntia ×viridiflora Britt. & Rose (pro sp.) is a cactus plant that is usually easy to grow in most environments. However, it can still be vulnerable to certain diseases and pests.

To manage this disease, ensure the soil is properly drained and reduce the frequency of watering, if possible.
Common pests that affect Opuntia ×viridiflora Britt. & Rose (pro sp.)
1. Scale insects: These are small, oval-shaped insects that attach themselves to the plant's pads. They cause the plant to become yellow and wilt. To manage this pest, you can use a brush to remove the scales, or you can apply insecticidal soap or horticultural oil.
2. Mealybugs: These are small, white insects that also attach themselves to the plant's pads. They cause yellowing and wilting of the plant and can cause the plant to produce a sticky substance called honeydew. To manage this pest, remove the infected pads and apply insecticidal soap or horticultural oil.
3. Spider mites: These are tiny, spider-like insects that are usually found on the underside of the plant's pads.
