Easter Lily Cactus
Echinopsis (ek-in-OP-sis)
Echinopsis or hedgehog cactus is a genus of cacti that are native to Peru, West Central and Southern Brazil and Northern Argentina. They are typically found along hillsides or in rocky crevices. There are 20 accepted species, and they are members of the cactus family (Cactaceae). The genus name originates from the Greek words, Ekihnos , meaning "sea urchin" and opsis, meaning "appearance." This is reflective of the spiny appearance of these plants. Each species has its own unique shape, size, and color. They may be small, flat, spherical, and form low-growing clumps, or they be tall, large, erect, and tree-like. Some species are often used as ornamental plants in landscapes or as houseplants. These plants are easy to grow and prefer well-drained, sandy and rocky soils. They enjoy full sun, but in very hot climates will benefit from some afternoon shade. When used as a houseplant, cactus potting mix is suggested to provide adequate soil drainage. The stems are able to retain water; therefore, these plants can survive in dry conditions. They can be propagated from seeds or stem cuttings. The succulent stems of these plants are usually green to blue-green and have ribs that run lengthwise of the plant. The spines vary depending on the species and may be yellow or white. These plants have large, funnel-shaped, showy flowers on elongated pedicels that bloom in the late evening during the spring or summer and usually only last for one day. They may have white or pink blooms; however, some species have red or orange blooms. The flowers have many petals and are arranged in a star-like pattern. The fruit appears hairy and globular, but it has a mushy, soft pulp on the interior. Species of this genus are often found in garden centers and are found in the landscape in the warm climates of the Southwestern United States. They may also used as container plants or houseplants.The species are easily hybridized, and there are many hybrids available whose flowers come in many colors and combinations.
