ABOUT
Echinopsis spiniflora, also commonly known as the spiny-flowered hedgehog cactus, is a distinctive plant that features a green to bluish-green stem, which is often cylindrical or spherical in shape. The surface of the stem is adorned with raised, bumpy areas called tubercles, out of which sharp spines emerge. These spines are usually a creamy white to yellow color and can vary in length. The plant is known for its remarkable flowers, which typically bloom near the top of the stem. The flowers are large, funnel-shaped, and exhibit a variety of colors, often vibrant shades ranging from white to pink, red, or purple. Each flower is supported by a floral tube that is also covered in small spines and woolly hairs, enhancing the spiky texture of the plant. The appearance of the spiny-flowered hedgehog cactus is a charming blend of its stout, spiny stem and the contrastingly soft, often brilliantly colored flowers that seem to crown the plant when in bloom. The overall impression is one of a hardy, resilient plant well adapted to harsh conditions, yet capable of producing spectacular floral displays that add bursts of color to its native arid landscapes.

Water
Sea Urchin Cactus requires moderate watering, generally about once a week during the active growing season. Water the cactus thoroughly, allowing the water to run through the drainage holes of the pot. Depending on the size of the pot and the plant, this could be approximately 16 to 32 ounces of water. During the winter months, reduce watering to once every three to four weeks as this cactus enters a dormancy period. Always ensure the soil is dry to the touch before watering again to prevent root rot.
Light
Sea Urchin Cactus thrives best in bright, indirect sunlight. It can handle some direct sun, especially in the cooler parts of the day, but intense afternoon sun can lead to sunburn on the cactus. The ideal spot for this plant would be in a room with east or west-facing windows or slightly shaded by a sheer curtain if placed in a south-facing window.
Temperature
Sea Urchin Cactus prefers warm temperatures and should be kept between 50 and 85 degrees Fahrenheit. It can withstand temperatures as low as 40 degrees Fahrenheit, but it's best to avoid exposure to frost. The ideal temperature range for this cactus is 70 to 80 degrees Fahrenheit for optimal growth.
Pruning
Sea Urchin Cactus doesn't require regular pruning, but it may benefit from the occasional removal of dead or damaged spines and flowers. Pruning can be done at any time of the year, but it's best done in the spring or early summer when the cactus is actively growing. If necessary, remove offsets to maintain the plant's shape and appearance.
Cleaning
As needed
Soil
The best soil mix for Sea Urchin Cactus includes a well-draining cactus mix with added perlite or pumice to increase aeration; a pH level around 6.0 to 6.5 is ideal.
Repotting
Sea Urchin Cactus should be repotted every two to three years or when it outgrows its pot to ensure healthy growth.
Humidity & Misting
Sea Urchin Cactus prefers low to moderate humidity levels and can tolerate dry indoor environments without the need for additional humidity.
Suitable locations
Indoor
Place Sea Urchin Cactus in bright indirect light indoors.
Outdoor

Life cycle
The Echinopsis spiniflora, commonly known as Sea-Urchin Cactus, begins its life cycle as a seed, often germinating in warm, moist soil in a process that can take several weeks. Upon sprouting, the seedling develops into a small cactus with a characteristic globular shape, and spines start to form as a defense mechanism. With proper care, including ample sunlight and minimal water, it goes through a vegetative growth phase, where it slowly increases in size. Over the years, when mature enough, typically in spring or early summer, the Sea-Urchin Cactus will produce large, showy flowers, usually at night, which are pollinated by nocturnal insects, birds, or bats. After pollination, fruits develop that contain new seeds, which when dispersed, can lead to the establishment of new plants, completing the cycle. The Sea-Urchin Cactus can live for several decades, and during its lifespan, it may go through the flowering and fruiting phase multiple times, depending on environmental conditions.
Propogation
Propogation time
Spring to Summer
The Sea Urchin Cactus (Echinopsis spiniflora), can be propagated through offsets, which are small new cacti that grow from the base of the parent plant. The best time to remove and plant these offsets is during the cactus's active growing season, which is typically in the spring or early summer. Using a clean, sharp knife or pair of scissors, the offsets can be carefully severed from the main plant, ensuring that each piece has a portion of the root. The cuttings should then be allowed to dry and form a callus over the cut surface for a few days to a week. Once callused, the offset can be planted in well-draining cactus soil. The soil should be kept slightly moist but not waterlogged until the offset establishes roots, a process that may take a few weeks. During this time, it's important to provide bright, indirect light and avoid direct sunlight, which could scorch the young plant.
