The Hoya silver dollar, scientifically known as Hoya carnosa variegata, is a popular houseplant cherished for its distinctive, round-shaped leaves. It is a variegated cultivar of the species Hoya carnosa, which is native to Eastern Asia. The botanical name “Hoya” honors the botanist Thomas Hoy, and “carnosa” refers to its fleshy leaves.
One of the key attractions of the silver dollar hoya is its unique foliage. The leaves are succulent-like and have a thick, waxy texture with a silver-gray hue. This gives the plant a striking appearance, making it a focal point in any indoor space.

Hoya Silver Dollar Care
To ensure the healthy growth of Hoya silver dollar, it’s crucial to provide optimal conditions. Here are some key factors to consider:
Light Requirements:
Hoya silver dollar thrives in bright indirect light. Placing it near a window where it can receive filtered sunlight throughout the day time. However, be cautious of direct sunlight as it can scorch the delicate leaves.
Temperature:
Hoya silver dollar prefers average room temperature, ranging from 60 to 75 degrees Fahrenheit (15 to 24 degrees Celsius). Avoid exposing the plant to extreme temperature fluctuations, such as drafts from windows or vents.
Humidity:
Maintaining moderate to high humidity levels is beneficial for Hoya silver dollar. You can increase humidity by misting the leaves regularly or placing the plant on a tray filled with water and pebbles. This helps to create a humid environment around the plant.
Soil:
Hoya Silver Dollar prefers well-draining soil to prevent waterlogging, which can lead to root rot. Use a mixture of well-draining potting soil, such as a cactus/succulent mix, combined with perlite or pumice to enhance drainage. You can add some compost or well-rotted organic material to enrich the soil and improve its nutrient content.
It prefers slightly acidic to neutral soil. Aim for a pH range between 6.0 and 7.0. You can test the soil pH using a pH testing kit available at gardening stores.
Container Size:
When choosing a container size for your Hoya Silver Dollar, it’s important to consider the plant’s growth habits and root system. While Hoya Silver Dollar generally prefers to be slightly root-bound, providing adequate space for growth is essential. Consider the size of your plant. If you are purchasing a young plant or propagating from cuttings, start with a smaller container. As your Hoya plant grows, you may need to upgrade the container size. Ensure that the container has drainage holes at the bottom. Good drainage is crucial to prevent waterlogging and root rot.
Watering Techniques:
Proper watering is essential for the Hoya silver dollar. It’s important to use well-draining soil to prevent waterlogged roots. Allow the topsoil to dry between waterings and then thoroughly water the plant, ensuring that excess water drains away. Overwatering can lead to root rot and other moisture-related issues.
Fertilizing Recommendations:
During the growing season, which typically spans spring and summer, it’s beneficial to fertilize Hoya silver dollar. Use a balanced houseplant fertilizer, following the instructions provided. This will provide the necessary nutrients for healthy growth and vibrant foliage.
Potting and Repotting:
When potting Hoya silver dollar, opt for a well-draining pot to prevent water from accumulating at the bottom. A suitable potting mix consists of a blend of peat moss, perlite, and a small amount of orchid bark. Repot the plant only when it outgrows its current pot, ensuring the new pot is slightly larger. Repotting every two to three years is generally sufficient.

Pruning Tips for Silver Dollar Hoya
Pruning is an essential aspect of maintaining the health and appearance of the Hoya Silver Dollar. Regular pruning helps promote bushier growth, control the size of the plant, and remove any damaged or diseased parts. Here are some guidelines for pruning Hoya Silver Dollar:
- Timing: The best time to prune Hoya Silver Dollar is during the active growing season, which typically occurs in spring or early summer. Avoid pruning during the dormant period, as it may hinder new growth.
- Equipment: Use clean, sharp pruning shears or scissors to make precise cuts. Sterilize the tools before pruning to prevent the spread of diseases or pests.
- Removing Dead or Damaged Parts: Start by inspecting the plant for any dead, yellowed, or damaged leaves, stems, or branches. These should be pruned back to healthy tissue. Make the cut just above a node, which is the point where a leaf or stem emerges from the main branch. This encourages new growth from that point.
- Controlling Size and Shape: If your Hoya Silver Dollar becomes too leggy or sprawling, you can prune it to maintain a more compact and aesthetically pleasing shape. Identify the areas that require pruning to achieve the desired shape. Trim back the stems, taking care not to remove too much foliage at once. Gradual pruning helps prevent shock to the plant.
- Maintenance: Regularly inspect your Hoya Silver Dollar for any new growth that might require pruning. Remove any excessive growth or stems that are crossing or rubbing against each other to maintain proper airflow and prevent potential damage.
Remember to provide adequate care, including proper watering, light exposure, and suitable soil conditions, to support the growth and recovery of your Hoya Silver Dollar after pruning. Pruning can rejuvenate the plant and promote healthier growth, but always ensure not to over-prune, as it may stress the plant.
Propagating Hoya silver dollar
If you want to expand your collection of Hoya silver dollar plants or share the joy of growing this unique houseplant with others, propagation is an excellent option. There are several methods you can choose from:
Stem Cuttings
One of the most common and successful methods of propagation is through stem cuttings. Here’s a step-by-step guide:
- Select a healthy stem with at least two to three leaf nodes.
- Using a clean, sharp pair of scissors or pruning shears, make a clean cut just below a leaf node.
- Optional: Apply rooting hormone to the cut end of the stem to encourage root development.
- Prepare a small pot filled with a well-draining potting mix.
- Create a hole in the potting mix and carefully insert the stem cutting.
- Gently press the soil around the cutting to secure it in place.
- Place the pot in a warm, well-lit area, away from direct sunlight.
- Keep the soil lightly moist to promote root development. Avoid overwatering to prevent rotting.
Layering
Another method of propagating Hoya silver dollar is through layering. Follow these steps:
- Identify a healthy and flexible stem that can be bent down to the soil level.
- Gently wound a small section of the stem where it will come into contact with the soil.
- Optional: Apply rooting hormone to the wounded section to enhance rooting.
- Bury the wounded section of the stem in the soil, leaving the tip exposed.
- Secure the stem in place using a small stake or U-shaped pin.
- Keep the soil consistently moist around the layered section.
- After a few weeks to months, roots will develop from the wounded section.
- Once roots are established, you can carefully cut the stem from the parent plant and repot it.
Both stem cuttings and layering are effective methods for propagating Hoya silver dollar. Experiment with both to determine which works best for you.
