Hoya benitotanii is a unique species within the popular Hoya genus, commonly known as wax plants. This particular plant captivates enthusiasts with its distinctive foliage and charming blooms. Originating from Southeast Asia, specifically the Philippines, it brings a touch of tropical allure to indoor plant collections. Its relatively easy care and appealing appearance make it a sought-after variety for both novice and experienced growers looking to expand their plant repertoire.
Unique Characteristics
Hoya benitotanii has large, glossy, and thick succulent leaves, which can measure up to 14 cm long and 5 cm wide. These leaves often start with reddish markings, especially when exposed to strong light, and mature into a plain, mid-green color. It exhibits a vining growth habit, capable of reaching lengths of up to 3 meters, and benefits from being grown on a support or in a hanging basket.
Its flowers are a notable feature, although the plant can be a reluctant bloomer and a slower grower. They are small, butter-yellow or creamy white, with a lighter yellow or pale orange corona, and measure up to 7 mm in diameter. These star-shaped flowers appear in clusters of up to 30 per umbel and have a light citrus fragrance, lasting for about seven days.
Hoya benitotanii Care
Light
Hoya benitotanii thrives in bright, indirect light, which is essential for encouraging growth and maintaining healthy foliage. While it can tolerate some direct morning sun, protect it from harsh, intense afternoon sunlight, which can scorch its leaves. If the plant is not receiving enough light, it may not produce its characteristic blooms.
Watering
Allowing the soil to dry out almost completely between waterings is key for Hoya benitotanii. Overwatering can lead to root rot, a common issue for Hoyas, so ensure proper drainage. When watering, do so thoroughly until excess water drains from the pot, then allow the top inch or two of soil to dry before the next watering. Reduced watering is recommended during the winter months.
Soil
A well-draining, airy potting mix that retains some moisture but allows excess water to drain freely is ideal for Hoya benitotanii. This plant dislikes clogged or compacted soil. An ideal mix includes components like orchid bark, perlite, pumice, horticultural charcoal, and a small amount of peat-based potting soil or coco husk. Some growers also include worm castings for natural fertilization.
Temperature and Humidity
Hoya benitotanii prefers warm environments, thriving in temperatures between 18-29°C (65-85°F). It does not tolerate temperatures below 10°C (50°F). While it can tolerate average household humidity, moderate to high humidity levels are beneficial for growth and health. Increasing humidity can be achieved by misting the leaves, using a pebble tray with water, or employing a humidifier.
Fertilizing
During the active growing season, spring and summer, Hoya benitotanii benefits from fertilization. A balanced, water-soluble fertilizer diluted to half-strength can be applied every 4-6 weeks. Some growers find success with orchid bloom fertilizer, which often has a higher phosphorus content to support flowering and root growth. Fertilizing should be avoided during the plant’s dormant period in fall and winter.
Propagating Hoya benitotanii
Hoya benitotanii is propagated through stem cuttings. To take a cutting, select a healthy stem with at least one leaf node, as nodes are where new roots will emerge. After cutting, allow the end to dry and form a callus for a few hours to prevent rot before placing it in a rooting medium.
Cuttings can be rooted in various mediums such as perlite, sphagnum moss, coco husk, or a chunky, well-draining soil mix. Some growers also root cuttings in water. Providing warmth and high humidity, such as by placing cuttings in a clear plastic bag or an enclosed container, helps in the rooting process. Roots develop within 4 to 6 weeks, after which the new plants can be potted into their permanent mix.
Troubleshooting Common Issues
Yellowing leaves on Hoya benitotanii indicate overwatering or underwatering. Overwatering, particularly in poorly draining soil, leads to root rot and yellowing, while prolonged underwatering also causes older leaves to yellow and develop crispy, brown margins. Adjusting watering practices to allow the soil to dry between applications resolves these issues.
A lack of blooming is a common concern for Hoya enthusiasts. Insufficient light is a primary reason for Hoya benitotanii not flowering, as bright, indirect light is necessary for flower production. Plant maturity also plays a role, with some Hoyas needing several years to bloom. Proper watering, adequate fertilization during the growing season, and ensuring the plant is not in an oversized pot can encourage blooms.
Common pests for Hoyas include sap-sucking insects such as mealybugs, aphids, and scale insects. These pests cause distorted or yellowing leaves and may leave sticky honeydew. Inspecting plants regularly and treating infestations with insecticidal soap, neem oil, or by wiping pests off with rubbing alcohol manage these issues.
