Crassula perforata ‘Ivory Towers’, also known as String of Buttons or Pagoda Plant, is a succulent recognized for its unique architectural form. This hybrid features stacked, triangular leaves arranged in a spiraling pattern along upright stems. The pale green leaves often exhibit reddish or creamy white edges, which intensify in color with ample sunlight. Its compact growth and striking foliage make it a favored ornamental houseplant.
Crassula Perforata Ivory Towers Care
Light Requirements
Crassula perforata ‘Ivory Towers’ flourishes in environments providing bright, indirect sunlight. Placing the plant near a south or west-facing window indoors can offer sufficient light. While it tolerates some direct morning or late afternoon sun, excessive exposure can cause the leaves to scorch or burn. Insufficient light may lead to etiolation, where stems stretch and leaves become sparse as the plant reaches for more light.
Watering
Watering involves a “soak and dry” method: water deeply until it drains from the pot, then allow the soil to dry completely before the next application. Overwatering is a common issue, leading to root rot, as these plants store water in their fleshy leaves. Signs of underwatering, such as shriveled or puckered leaves, indicate the plant needs moisture.
Soil and Potting
A well-draining, gritty soil mix is essential for Crassula perforata ‘Ivory Towers’ to prevent waterlogging and root rot. A suitable mix often includes 50% to 70% mineral grit such as coarse sand, pumice, or perlite blended with potting soil. Terracotta pots are often preferred due to their porous nature, which allows for better airflow and quicker drying of the soil. Repotting should occur when the plant outgrows its current container or when the soil needs refreshing.
Temperature and Humidity
Crassula perforata ‘Ivory Towers’ thrives in typical indoor temperatures, preferring 65°F to 75°F (18°C-24°C). It is not tolerant of frost and should be brought indoors if temperatures drop below 30°F (-1.1°C). The plant is well-suited to average household humidity and does not require high humidity. Maintaining good air circulation helps prevent fungal issues.
Fertilizing
Fertilization is not necessary for Crassula perforata ‘Ivory Towers’ but can support vigorous growth during its active season (spring and summer). Apply a diluted, low-nitrogen liquid fertilizer. Over-fertilizing can harm the plant, so use a quarter-strength solution once every few weeks. Do not fertilize during the plant’s dormant period (winter), as it can weaken or burn the plant.
Propagating Crassula Perforata Ivory Towers
Propagating Crassula perforata ‘Ivory Towers’ is commonly achieved through stem or leaf cuttings. For stem cuttings, snip a healthy stem section. Allow the cut end to dry and callous for a few days to a week to prevent rot. Once calloused, insert the cutting into well-draining succulent soil.
Leaf propagation involves gently twisting a healthy leaf from the stem. Let the leaf callous for several days before placing it on top of or slightly pressed into moist succulent soil. New plantlets emerge from the leaf base. Keep the soil lightly moist until roots and new growth establish.
Common Problems and Solutions
Crassula perforata ‘Ivory Towers’ can encounter common issues. Overwatering is a frequent problem, leading to mushy, discolored leaves and root rot. Reduce watering frequency and ensure the soil dries completely between waterings. For severe root rot, repot into fresh, dry soil after trimming affected roots.
Underwatering causes leaves to shrivel or become crispy. A thorough watering can rehydrate the plant. Pest infestations, such as mealybugs, can also affect ‘Ivory Towers’. These insects can be removed with a cotton swab dipped in rubbing alcohol or by applying a diluted neem oil solution.
