The Plectranthus coleoides ‘Purple’, commonly known as Purple Swedish Ivy, is a favored houseplant, admired for its distinctive foliage and graceful, cascading growth. Its relatively simple care requirements make it a welcoming addition for both new and experienced plant enthusiasts.
The Allure of Purple Swedish Ivy
This plant, Plectranthus coleoides ‘Purple’, is not a true ivy and belongs to the mint family. Its leaves feature deep green upper surfaces with a striking purple tint, especially when exposed to sufficient light, while their undersides boast a rich purple hue. This vibrant coloration, combined with its fast-growing, trailing vines, makes it an excellent choice for hanging baskets or as a “spiller” in mixed container arrangements. The plant occasionally produces small, inconspicuous tubular lavender or white flowers, though its primary appeal is its attractive foliage.
Essential Care for Thriving Purple Swedish Ivy
Consistent care helps Purple Swedish Ivy maintain its vibrant coloration and robust growth. Understanding its specific needs for light, water, soil, temperature, humidity, and fertilization contributes to its overall health.
Light
Purple Swedish Ivy thrives in bright, indirect light. Place it near an east or west-facing window, or a south-facing window with sheer curtains. Insufficient light may cause the purple coloration to fade, resulting in a greener appearance. Avoid direct, harsh afternoon sun, as it can scorch the leaves.
Watering
Maintain consistent soil moisture for Purple Swedish Ivy, but avoid waterlogging. Allow the top inch of soil to dry out between waterings. Overwatering can lead to root rot, so ensure proper drainage. Wilting leaves indicate underwatering, which should recover once watered. During winter, reduce watering frequency as growth slows.
Soil
A well-draining potting mix is suitable for Purple Swedish Ivy, preventing water accumulation around the roots. A peat-based mix, often amended with perlite or sand, provides good aeration and drainage. The plant prefers a slightly acidic to neutral pH range, between 5.5 and 7.5.
Temperature and Humidity
Purple Swedish Ivy prefers average room temperatures, between 60°F and 75°F (15°C and 24°C). It is not frost-tolerant and requires protection from cold. This plant thrives in moderate to high humidity. To increase humidity in drier indoor environments, consider misting leaves, grouping it with other plants, or placing the pot on a pebble tray.
Fertilization
During its active growing season (spring and summer), Purple Swedish Ivy benefits from regular fertilization. Apply a balanced liquid fertilizer, diluted to half strength, every two to four weeks to support lush foliage growth. Reduce or pause fertilization during fall and winter when growth slows. Adhere to recommended dilution rates to avoid over-fertilization issues.
Multiplying Your Purple Swedish Ivy
Propagating Purple Swedish Ivy is straightforward, primarily done through stem cuttings. While successful year-round, spring and summer are ideal. Choose healthy, non-flowering stems 3 to 6 inches long with at least one leaf node. Remove leaves from the bottom inch or two of the cutting to prevent rotting.
Cuttings can be rooted in water or directly in moist soil. For water propagation, place cuttings in room-temperature water, ensuring leafless nodes are submerged. Change the water every few days. Roots typically form within two to four weeks.
For soil propagation, insert cuttings into a well-draining potting mix, keeping the soil consistently moist but not soggy. Warmth and bright, indirect light support successful rooting.
Addressing Common Challenges
While Purple Swedish Ivy is generally resilient, issues can arise, signaling a need for care adjustment. Recognizing these signs allows for timely intervention.
Leggy growth, characterized by long, sparse stems, indicates insufficient light. Moving the plant to a brighter location with indirect light encourages bushier growth. A loss of purple coloration, where leaves appear greener, also points to inadequate light exposure, as discussed in the Light section.
Yellowing leaves can be a symptom of overwatering or nutrient deficiencies. Ensure the soil dries slightly between waterings and provide regular, diluted fertilization during the growing season. Common pests like spider mites and mealybugs may affect Purple Swedish Ivy. Regular inspection and prompt treatment with insecticidal soap or neem oil can manage infestations.
