Hoya lucardenasiana is a highly sought-after houseplant that captivates enthusiasts with its distinctive foliage and charming blooms. This unique plant offers a rewarding experience for those looking to expand their indoor garden. Its manageable care makes it a beautiful addition.
Understanding Hoya lucardenasiana
Hoya lucardenasiana is native to Luzon, the largest island in the Philippines, discovered in 2007 and formally published in 2009. Its leaves are vibrant green, ovate, smooth, and slightly glossy. These leaves are typically around two inches long and one and a half inches wide, developing a reddish tint when exposed to stronger light.
When in bloom, this Hoya produces stunning clusters of small, revolute flowers, dark pink to deep maroon or wine, measuring about 8mm in diameter. Each umbel can feature up to 15 individual flowers, covered in glossy nectar and emitting a sweet butterscotch fragrance. Blooms last approximately five days, and the plant flowers even at a small size. Hoya lucardenasiana has a thick, non-twining stem, making it suitable for a hanging basket display over upright support. While slow to establish, it grows well and blooms frequently once settled.
Caring for Hoya lucardenasiana
Light
Hoya lucardenasiana thrives in bright, indirect light. Shield the plant from harsh, direct sunlight, as this can scorch its leaves. A few hours of gentle morning sun can encourage more vigorous growth and abundant flowers. Inadequate light may lead to elongated stems and hinder blooming.
Watering
Watering prevents common issues with Hoya lucardenasiana. Allow the soil to dry out significantly between waterings; the top inch or two of the potting medium should feel dry before rewatering. Thoroughly soak the plant until water drains from the bottom of the pot, ensuring the entire root ball is moistened. Overwatering causes root rot, while underwatering may cause leaves to become limp, wrinkled, or shriveled. During cooler months or reduced growth, decrease watering frequency.
Soil
Potting medium impacts water and nutrient absorption. As an epiphyte, Hoya lucardenasiana requires a well-draining and airy soil mix. Avoid standard garden soil, as it retains too much moisture and encourages fungal growth. A good mixture includes orchid bark, coco husk, coco coir, perlite, and horticultural charcoal, which ensure good aeration and drainage while retaining moisture. This chunky, fast-drying blend supports healthy root development and prevents waterlogging.
Temperature and Humidity
Hoya lucardenasiana prefers warm, consistent temperatures, ranging between 60°F (15°C) and 85°F (29°C). It is sensitive to cold and should not be exposed to temperatures below 50°F (10°C). The plant benefits from moderate to high humidity levels. While it tolerates slightly lower humidity, providing additional moisture through misting, a pebble tray, or a humidifier improves its vigor. Humidity of 50-60% is beneficial. A combination of low temperatures and high humidity can predispose the plant to fungal infections.
Fertilizing
Regular fertilization during the active growing season supports healthy growth and abundant blooms. During spring and summer, feed Hoya lucardenasiana every 2-4 weeks with a balanced liquid fertilizer. A 2-2-2 or 3-1-2 NPK ratio is suitable for overall health. To encourage flowering, consider switching to a fertilizer with a higher phosphorus content, like 5-10-3, for a couple of months before blooming. Always dilute the fertilizer to half-strength to prevent over-fertilization. As the plant enters its semi-dormant phase in fall and winter, reduce or cease fertilization. Periodically flushing the potting medium with plain water helps prevent mineral salt buildup.
Propagating Hoya lucardenasiana
Stem cuttings are the most common method for propagating Hoya lucardenasiana. Select a healthy stem section approximately 4-6 inches long, including at least two to three nodes. Remove any leaves from the lowest node or two to prevent rotting. Dipping the cut end in rooting hormone can enhance root development.
Cuttings can be rooted in water or directly in a well-draining, airy medium. For rooting in a medium, a mix of perlite, sphagnum moss, or coco coir provides aeration and moisture retention. High humidity is beneficial; achieve this by placing the cutting in a clear plastic bag or under a humidity dome. Roots form within 3 to 6 weeks, after which the new plant can be potted into a permanent pot.
Common Issues and Solutions
Hoya lucardenasiana may encounter some common issues. Overwatering leads to root rot, yellowing leaves, and mushy stems. Ensure the potting medium dries out adequately between waterings and always use a pot with proper drainage. Underwatering can manifest as limp, wrinkled, or shriveled leaves; a thorough watering will revive the plant.
Insufficient light or nutrient imbalance can cause a lack of blooming. Adjusting the plant’s location to receive brighter, indirect light and ensuring a fertilizer with adequate phosphorus during the growing season encourages flowering. Hoya lucardenasiana is susceptible to common houseplant pests, including mealybugs, aphids, spider mites, and scale insects. Manage these sap-sucking pests by wiping them off with rubbing alcohol, applying insecticidal soap, or using neem oil. Maintaining good air circulation and avoiding wetting the leaves at night helps prevent fungal diseases like leaf spot and root rot, which are exacerbated by excessive moisture.
