This plant prefers full sunlight and is suitable for growing in both dry and humid conditions. It is easy to cultivate, making it a great addition to any garden.
Watering Needs
Passerina filiformis L. subsp. glutinosa is a drought-tolerant plant and can survive on minimal water. However, it is essential to keep the soil moist during the initial stages of growth. Once the plant has established itself, reduce the amount of water it receives. Ensure that the soil is not waterlogged as this can damage the roots and kill the plant.
Fertilization
Passerina filiformis L. subsp. glutinosa does not require heavy fertilization. However, you can apply a slow-release granular fertilizer during the initial stages of growth to provide some essential nutrients. Avoid applying too much fertilizer, which can lead to poor growth and weak stems. Instead, use a balanced fertilizer, and follow instructions carefully when applying it.
Pruning
Passerina filiformis L. subsp. glutinosa is a low-maintenance plant that requires minimal pruning. However, you can prune it to remove any dead or damaged branches to promote healthy growth. Prune the plant during the fall or winter months when it is dormant. Ensure that you use sterilized pruning tools to prevent the spread of disease and infection.
Propagation of Passerina filiformis L. subsp. glutinosa
Passerina filiformis L. subsp. glutinosa, commonly known as the sticky blue-salvia, can be propagated through different methods such as:
Seed Propagation
This method involves collecting seeds from mature plants and sowing them in seed trays during the spring season. The seeds must be sown in well-draining potting soil and lightly covered with a layer of soil or sand. After sowing, the seeds should be kept moist, and they usually germinate within two to four weeks.
Cutting Propagation
Cuttings can be taken from the plant during the spring season, and they should be at least two inches in length. The stem cuttings should be dipped in rooting hormone and planted in well-draining soil. It is best to place the planted cuttings in a shaded area to prevent them from drying out.
Division Propagation
The sticky blue-salvia can also be propagated through division. This method involves carefully digging up the plant and separating the roots and stems into smaller sections. Each section should have some stem and root attached to it. The divided plant sections are then replanted in well-draining soil and watered.
Regardless of the propagation method used, it is important to keep the soil moist but not waterlogged and provide the plants with some shade until they are established.
Disease Management
Passerina filiformis L. subsp. glutinosa (Thoday) C.L.Bredenkamp & A.E.van Wyk is a relatively hardy plant with low susceptibility to diseases. However, some common diseases that might affect the plant include:
- Root Rot: Root rot is a fungal disease that can be caused by overwatering, poor drainage, or soil-borne pathogens. To prevent root rot, make sure the soil is well-draining and avoid overwatering.
- Leaf Spot: Leaf spot is a fungal disease that can cause spots or lesions on the leaves. To prevent leaf spot, avoid overhead watering and remove infected leaves as soon as possible.
If you notice any signs of disease on your Passerina filiformis L. subsp. glutinosa (Thoday) C.L.Bredenkamp & A.E.van Wyk, it is important to take action immediately. Remove infected plant material and apply a fungicide if necessary.

- Aphids: Aphids are small, soft-bodied insects that can cluster on the underside of leaves or in new growth. They can be controlled with insecticidal soap or neem oil.
- Spider Mites: Spider mites are tiny arachnids that can cause yellowing or discoloration of leaves. They can be controlled with insecticidal soap or neem oil.
Regular inspection of your Passerina filiformis L. subsp. glutinosa (Thoday) C.L.Bredenkamp & A.E.van Wyk can help you identify any pest problems early on. Remove any infected plant material and use organic pest control methods whenever possible.
