Epiphyllum ‘Clown’ is a captivating hybrid cactus known for its unique appearance and spectacular blooms. This plant belongs to the Epiphyllum genus, often called orchid cacti due to their epiphytic nature, growing on trees rather than in soil. Its flattened, leaf-like stems provide interesting texture even when not in flower. Its large, intricate flowers display striking white, pink, and raspberry-red petals. These impressive blooms can reach up to 8 inches wide and often carry a delightful fragrance.
Caring for Epiphyllum ‘Clown’
Light Requirements
Epiphyllum ‘Clown’ thrives in bright, indirect light, mimicking its natural environment beneath tree canopies. Harsh, direct sunlight can scorch and discolor its stems. An east-facing window or shaded patio with dappled sunlight is ideal. Too much light can turn stems reddish, indicating stress. Conversely, insufficient light leads to leggy, weak growth and poor blooming.
Watering Needs
Maintaining appropriate watering practices is crucial for Epiphyllum ‘Clown’. The plant prefers its soil to dry out between waterings to prevent root rot. During the active growing season (spring and summer), water thoroughly until water drains from the bottom. In late fall and winter, during its rest period, significantly reduce watering, providing just enough moisture to prevent shriveling. Overwatering during dormancy is detrimental.
Soil and Potting
A well-draining, airy potting mix is essential for Epiphyllum ‘Clown’. A suitable mix includes orchid bark, perlite, pumice, or coarse sand, blended with a small amount of coco coir or peat moss. This ensures excellent aeration and prevents waterlogging. Pots with ample drainage holes are equally important. These plants prefer to be slightly root-bound, so avoid oversizing the pot.
Temperature and Humidity
Epiphyllum ‘Clown’ prefers warm conditions during its growing season and cooler temperatures during dormancy. During spring and summer, temperatures between 60-80°F (15-27°C) are suitable. They are sensitive to frost and require protection from freezing temperatures, ideally above 35°F (1.7°C). While they tolerate average household humidity, they appreciate higher levels, which can be provided by occasional misting in dry environments.
Fertilizing
Regular fertilization supports robust growth and flowering. During the active growing season (spring through summer), apply a balanced liquid fertilizer (e.g., 10-10-10) every two to four weeks. Reduce or stop fertilizing entirely during fall and winter dormancy. Once flower buds form (late winter or early spring), switch to a higher phosphorus fertilizer (e.g., 2-10-10) to encourage abundant blooms.
Encouraging Stunning Blooms
Achieving spectacular blooms requires a specific dormancy period. Starting in late fall (around November), significantly reduce watering and expose the plant to cooler temperatures, ideally 30-55°F (-1 to 13°C), staying above freezing. This cool, dry rest stimulates flower bud formation on last year’s growth. Maintain these conditions until buds visibly appear in late winter or early spring.
Once buds are noticeable, gradually resume regular watering and apply a higher phosphorus fertilizer to support bloom development. Avoid moving or disturbing the plant once buds have set, as this can cause them to drop. Blooms typically appear in spring or summer, unfurling sequentially. Adequate light during this period ensures buds develop fully and open beautifully.
Propagating Epiphyllum ‘Clown’
Propagating Epiphyllum ‘Clown’ is readily accomplished through stem cuttings. Select a healthy, mature stem segment, at least 4-6 inches long, free from blemishes or damage. After cutting, allow the severed end to callus for several days to a week in a dry, warm place. This callusing prevents rot once planted.
Prepare a well-draining rooting medium, similar to the plant’s regular potting mix, using perlite and a small amount of peat or coco coir. Insert the callused end about 1-2 inches deep into the moist medium, ensuring correct orientation. Maintain consistent, moderate moisture in the rooting medium without waterlogging. Rooting typically occurs within 3 to 6 weeks; new growth signals successful establishment.
Troubleshooting Common Problems
Limp or yellowing stems often indicate improper watering. Overwatering, especially during dormancy, can lead to root rot, causing soft, discolored stems. Conversely, severely underwatered plants may also exhibit limpness and shriveling. Always check soil moisture before watering. Adjusting the watering schedule to allow soil to dry out between applications can resolve these issues.
A lack of blooms often stems from insufficient or incorrect dormancy. Without a cool, dry rest period, the plant may not initiate bud formation. Appropriate light exposure and correct fertilizer balance during the growing season also contribute to flowering.
Pests like mealybugs or scale can infest Epiphyllum ‘Clown’, appearing as small, cottony masses or bumps on stems. These can be addressed by gently wiping them off with rubbing alcohol or applying an insecticidal soap. Scorched or discolored foliage (reddish or brown patches) usually results from too much direct sun exposure. Moving the plant to a brighter, indirect light location can prevent further damage.
