Codonanthe devosiana ‘Paula’ is a captivating plant that brings natural elegance to indoor spaces. This dainty trailing plant, belonging to the Gesneriaceae family, is admired for its delicate, bell-shaped flowers and lush foliage. Its charming white blossoms, often tinged with soft pink accents, make it a delightful addition to any home. The plant’s cascading habit makes it appealing for display in hanging baskets or on shelves, where its long stems and dark purple-green velvety leaves can shine.
Optimal Growing Environment
Optimal environmental conditions are fundamental for Codonanthe devosiana ‘Paula’. This plant thrives in bright, indirect light, mimicking its natural habitat in the dappled canopy of trees. Direct sunlight should be avoided, as it can scorch the leaves.
Maintain a consistent temperature range between 65 to 85 degrees Fahrenheit (18 to 29 degrees Celsius). While the plant can tolerate slightly cooler conditions, temperatures below 40 degrees Fahrenheit (5 degrees Celsius) can be detrimental. High humidity is also essential.
Average household humidity may suffice, but ‘Paula’ benefits from increased moisture, especially during drier months. Placing the pot on a pebble tray filled with water or using a room humidifier can provide moisture. Browning leaf edges often indicate insufficient humidity.
The ideal potting mix for Codonanthe devosiana ‘Paula’ is a well-draining, airy substrate. Given its epiphytic nature, meaning it grows on other plants in the wild without much soil, a light, porous mix similar to orchid mixes is suitable. Components like peat, coconut fiber, clay balls, or bark mulch ensure drainage and aeration, preventing waterlogging.
Essential Care Practices
Water Codonanthe devosiana ‘Paula’ by allowing the top layer of soil to dry slightly between applications. A good method involves submerging the pot’s root ball in room-temperature water for a few minutes until it is thoroughly saturated, then allowing it to drain completely.
Avoid overwatering, as this plant is susceptible to soggy roots and decline. While it can endure short periods of drought, consistent moisture promotes vigorous growth and abundant flowering. During the summer, watering twice a week may be appropriate, reducing to once a week in winter.
Fertilization supports plant health and encourages blooming, particularly during spring and summer. A general-purpose houseplant fertilizer, diluted to about one-quarter teaspoon per gallon of water, can be applied monthly. Alternatively, a solution designed for flowering plants can be used every two to three weeks.
Pruning Codonanthe devosiana ‘Paula’ is minimal, focusing on maintaining its shape and removing dead leaves. Cutting a sprig can encourage new branching for a bushier appearance. For rejuvenation, trim back about a third of older, woody portions after the main blooming season.
Repotting is needed every two to three years to refresh soil and provide root space. When repotting, choosing a shallow pot, approximately 12 cm in diameter and 9-10 cm in height, is beneficial. This accommodates its growth habit and prevents excessive moisture retention.
Propagation Methods
Propagating Codonanthe devosiana ‘Paula’ is most commonly achieved through stem cuttings. Select healthy trailing stems that are 4 to 6 inches (10-15 cm) long, ensuring each cutting includes at least three sets of leaves. Cuttings can be rooted in water or a well-draining soil mix.
When rooting in water, change the water frequently to prevent stagnation. For soil propagation, dipping the cut end in rooting hormone can enhance success rates before planting. Placing several cuttings in a single pot creates an immediately fuller plant. Providing a humid environment, such as within a terrarium or under a plastic dome, aids rooting.
Seed propagation is another option, although less common for home growers. Codonanthe plants can self-pollinate and produce small, orange berries containing seeds. These seeds, which resemble tiny grains, should have their fleshy coating removed before storage or sowing. Seeds can be sown indoors at the end of winter, transplanting seedlings into hanging pots.
Troubleshooting Common Issues
Yellowing leaves can indicate either excessive light exposure or overwatering. If the leaves develop brown tips or edges, this often indicates insufficient humidity or too much direct sun.
Wilting leaves, while sometimes a sign of underwatering, can also occur if the plant experiences short droughts, leading to leaf loss and delayed flowering. Adjusting watering frequency and ensuring consistent humidity can resolve these issues.
Pest infestations are a concern, with mealybugs, spider mites, and aphids being common. Regularly inspecting the plant’s foliage, especially the undersides of leaves, allows early detection. Prompt intervention with appropriate organic or chemical treatments can manage these pests, preventing damage.
A lack of flowering is often remedied by optimizing environmental conditions. Insufficient light is a frequent cause, as is inconsistent watering. Providing adequate indirect light and consistent moisture, along with regular fertilization using a bloom-boosting formula, encourages blooming.
