The Hoya genus features diverse plants with unique foliage and fragrant, star-shaped flowers. Hoya lacunosa is known for its compact size and cinnamon-scented blooms. ‘Asami Clone 2’ is a sought-after cultivar, appealing to enthusiasts for its aesthetic qualities.
Understanding Hoya Lacunosa Asami Clone 2
Hoya lacunosa ‘Asami Clone 2’ is distinguished by its leaf characteristics and growth habit. It typically features darker green leaves, often with pronounced variegation or “splash” patterns. Its leaves display creamy white margins that can turn pink in sufficient light. These small, thin leaves contribute to its delicate appearance.
Unlike climbing Hoya varieties, ‘Asami Clone 2’ grows as a hanging plant, suitable for baskets or shelves. Its star-shaped, white flowers emit a strong, sweet, cinnamon-like fragrance, especially in the evenings.
Optimal Care for Asami Clone 2
Light
‘Asami Clone 2’ thrives in bright, indirect light, mimicking its natural habitat. Place it near an east or west-facing window for filtered sunlight. While it tolerates some direct morning sun, intense afternoon rays can scorch its delicate leaves. Insufficient light may hinder growth and limit flower production.
Watering
Like many Hoyas, ‘Asami Clone 2’ prefers to dry out slightly between waterings. Water thoroughly when the top 1-2 inches of soil feel dry, ensuring excess water drains to prevent root rot. Reduce watering frequency in cooler months as growth slows. Its thinner leaves mean it stores less water than some other Hoyas, so avoid prolonged dryness.
Humidity and Temperature
This Hoya enjoys moderate to high humidity (40-80%). While it adapts to average indoor humidity (40-50%), increasing it to 60% or more encourages robust growth and frequent blooming. A humidifier or pebble tray helps maintain adequate moisture. It thrives in typical household temperatures (65-85°F / 18-29°C). Protect it from cold drafts and avoid temperatures below 50-55°F (10-13°C), as prolonged cold can cause damage.
Soil and Potting
A well-draining, airy potting mix is suitable, reflecting its epiphytic nature. A good blend includes orchid bark, perlite, and a small amount of peat or coco coir. This mix prevents waterlogging and ensures aeration. Repot every 2-3 years, or when root-bound, as Hoyas often prefer snug pots, which can encourage blooming.
Fertilization
During spring and summer, regular fertilization supports the plant’s health and blooming. Use a balanced liquid fertilizer at half strength with every or every other watering. This diluted feeding provides steady nutrients. Hydroponic or foliage-specific fertilizers are also suitable.
Propagating Asami Clone 2
Propagate ‘Asami Clone 2’ using stem cuttings. Take a healthy cutting with at least one or two nodes, as roots develop from these points. The cutting should be 4-6 inches long with a few leaves attached. After making a clean cut, allow it to air dry and callus for a few hours (up to 24 hours) to prevent rot.
Cuttings can be rooted in water or a well-draining soil mix. For water propagation, place the cutting in a glass with water, ensuring nodes are submerged but leaves remain above the water line. Change water weekly. For soil propagation, plant the cutting in a light, airy medium, burying at least one node. Consistent moisture and warmth, possibly with a clear plastic bag or dome, encourage successful rooting.
Common Challenges and Solutions
Common issues for ‘Asami Clone 2’ often relate to environmental factors. Yellowing leaves indicate either overwatering or too much direct sunlight. Mushy yellow leaves suggest root rot from overwatering; crispy yellowing suggests strong light exposure. Adjusting watering habits to allow the soil to dry and providing bright, indirect light can resolve these issues.
Browning leaf edges often point to low humidity or inconsistent watering. Increase ambient humidity with a humidifier or pebble tray and ensure consistent moisture, without waterlogging, to mitigate this.
Lack of new growth might stem from insufficient light or a need for fertilization. Move the plant to a brighter location or initiate a diluted feeding schedule during the growing season to stimulate new development. Pest problems, such as mealybugs, aphids, or spider mites, can occur, typically addressed by isolating the plant and treating with insecticidal soap or neem oil.
