Wright's hedgehog cactus Echinopsis backebergii subsp. wrightiana
ABOUT
Echinopsis backebergii subsp. wrightiana, commonly known as the Wright's cactus, is a visually striking succulent that captivates with its intricate form and vibrant blossoms. This cactus features a globular, spherical, or sometimes columnar body with prominent, evenly spaced ribs running vertically along its surface. Its skin is a green to blue-green, supporting numerous areoles from which sharp, needle-like spines emerge. These spines can vary in color from pale yellows to reds and browns, adding a layer of texture and protection to the plant. Most notably, the Wright's cactus is celebrated for its large, funnel-shaped flowers that burst forth in an array of brilliant hues. These blooms are particularly showy, often exhibiting vibrant colors such as deep reds, purples, oranges, or whites. The flowers provide a stark contrast to the spiny, rugged appearance of the cactus itself. The petals are soft and satiny, inviting a range of pollinators to visit. This plant exhibits a charming combination of formidable defenses and delicate beauty, making it a fascinating and attractive species for cactus enthusiasts and gardeners alike.

WaterFor the Lobivia wrightiana, a native desert cactus, it is essential to water sparingly, mimicking its natural arid environment. During its active growth period in spring and summer, water the Lobivia wrightiana every 7-10 days, providing enough water to soak the soil and then allowing it to dry out completely between waterings. Use approximately 8-10 ounces of water for a small 4-inch pot, adjusting the amount for larger pots. In winter, reduce watering to once a month or less, depending on the humidity and temperature, to prevent root rot.
LightLobivia wrightiana thrives best in full sun to partial shade conditions. The ideal spot for this cactus is a location where it receives direct sunlight for at least 4-6 hours every day. If grown indoors, a sunny windowsill or a south-facing window would provide the right amount of light. It can tolerate some light shade, especially in the hottest parts of the day, to prevent sunburn.
TemperatureLobivia wrightiana prefers temperatures that range from 50°F to 85°F for optimal growth, reflecting its desert heritage. It can tolerate a minimum temperature of about 40°F, but exposure to frost or prolonged periods below this point can be detrimental. During the hot summer months, it can handle high temperatures as long as appropriate watering is maintained.
PruningPruning is not a routine requirement for the Lobivia wrightiana. However, any dead or damaged spines or flowers can be gently removed to maintain the plant's appearance and health. The best time for any necessary pruning is in the spring, right before the growth period begins. This plant doesn't often outgrow its pot or space, so significant pruning for size control generally isn't necessary.
CleaningAs needed
SoilThe best soil mix for the Lobivia (Echinopsis backebergii subsp. wrightiana) is a well-draining cactus mix consisting of regular potting soil, coarse sand, and perlite or pumice in equal parts. The soil pH should be slightly acidic to neutral, ideally ranging between 6.0 and 7.5.
RepottingLobivia (Echinopsis backebergii subsp. wrightiana) should generally be repotted every two to three years or when the cactus has outgrown its container. Repotting is best done during the warmer growing season.
Humidity & MistingLobivia (Echinopsis backebergii subsp. wrightiana) prefers low to moderate humidity levels and can tolerate dry air, characteristic of arid environments where humidity is typically below 50%.
Suitable locationsIndoor
Provide bright light, well-draining soil, low humidity.

Life cycleEchinopsis backebergii subsp. wrightiana, commonly known as Lobivia backebergii, begins its life cycle as a small, round seed which, when sown in well-draining soil and provided with warmth, moisture and light, will germinate and sprout a tiny cactus seedling. This young cactus grows slowly, developing a spherical to short cylindrical stem with ribs lined with areoles that produce spines. After several years, the mature Lobivia backebergii reaches flowering maturity and produces vibrant funnel-shaped flowers, often in shades of red, orange, or yellow, which bloom during the day and close at night. The flowers are pollinated by insects, birds, or bats, leading to the formation of small, fleshy fruits that contain seeds, thus completing the reproductive cycle. As a perennial, Lobivia backebergii can continue to grow and produce flowers and fruits for many years. Offsets may also form at the base of the parent plant, contributing to new individuals and colony expansion.
PropogationPropogation time
Spring to Summer
For the Echinopsis backebergii subsp. wrightiana, commonly referred to as the Lobivia wrightiana cactus, propagation is commonly done through the process of seed sowing or by rooting offsets. The most popular method among enthusiasts is through offsets, which are small clones that grow at the base of the parent plant. To propagate using offsets, one would gently remove an offset from the main plant, preferably during the warm growing season when the cactus is actively growing. After removal, the offset should be allowed to dry for a few days to form a callous over the cut surface to prevent rot. Once calloused, the offset can be planted in a well-draining cactus potting mix. The soil should be kept slightly moist until the offset establishes roots. This process can take several weeks, and the new plants should not be exposed to intense sunlight during this period to avoid sunburn.
