Overview
Sutera affinis auct. is a flowering plant species that belongs to the family of dogbane or milkweed. This perennial plant species is commonly known as trailing lobelia or creeping baby's breath. Its scientific name is derived from the Greek word "soutara," which means "a cord," referring to the plant's thin and stringy stems that grow up to 12 inches long.
Origin
Sutera affinis auct. is native to southern Africa, where it can be found growing in damp, shady areas such as forests, streambanks, and marshes. Due to its beautiful, delicate flowers, the plant has been introduced and cultivated in other regions of the world, including Europe, North America, and Asia.
Appearance
Sutera affinis auct. is a low-growing, creeping plant that spreads up to 18 inches wide. Its stems are thin and thread-like, producing clusters of small, white or purple, star-shaped flowers from late spring to fall. The plant's leaves are oval-shaped, about 1 inch long, and light green in color.
Uses
The trailing lobelia is a popular ornamental plant that is used in hanging baskets and containers as well as as a groundcover. It is known for its ability to attract butterflies and other insects, making it a favorite among gardeners. In traditional medicine, the plant has been used to treat respiratory and digestive disorders.
However, it's worth noting that the trailing lobelia is toxic if ingested, and excessive handling of the plant may cause allergic reactions in some individuals. Therefore, it's important to handle the plant with care and keep it out of reach of children and pets.
Light Requirements
Sutera affinis auct. thrives in bright light and partial shade conditions. Direct sunlight can scorch the leaves and hinder its growth. Therefore, keeping the plant in a shaded region or under a partially covered patio is ideal.
Temperature Requirements
Sutera affinis auct. grows best in warm temperatures ranging between 18°C to 24°C. Temperatures above 26°C can cause stress to the plant. In cold regions, the plant can be grown indoors, where room temperature is maintained.
Soil Requirements
The plant prefers well-draining, fertile soils with a neutral pH between 6.0 – 7.5. The soil mixture should contain organic matter to enhance the soil quality. When planting in a container, it is recommended to use a potting mix with perlite, peat moss, and vermiculite to provide the necessary drainage.
Cultivation Methods
Sutera affinis auct., also known as snowflake, is an incredibly stunning plant that will make a beautiful addition to any garden. The plant is relatively easy to cultivate, so long as you provide the necessary growing conditions. Start by selecting an area in your garden that receives partial shade. The plant prefers well-draining soil, although it is not overly fussy and will tolerate a range of soil types.
Plant the Sutera affinis auct. in early spring after the threat of frost has passed. The plant can grow up to 6 inches tall but spreads rather than growing vertically. Therefore it is essential to plant the snowflake approximately 4-6 inches apart to accommodate its spreading habit. Water the new plant well and observe it as it grows, making any necessary adjustments to the soil or sunlight received.
Watering Needs
Like most plants, Sutera affinis auct. needs regular watering, especially when first establishing it in the garden. Ensure that the soil is moist, but not overly wet, as this can cause root rot. When watering, do it in the early morning, and ensure that the soil is adequately moistened. The plant will need less frequent watering when it becomes established in the garden, but it's essential to water it regularly, particularly in hot and dry weather events.
Fertilization
After planting Sutera affinis auct., you can fertilize it with a slow-release, balanced fertilizer. Doing this once a month will keep your plant healthy and thriving. However, care must be taken not to over-fertilize the plant as this is harmful to it. If your Sutera affinis auct. appears to be growing well and healthy, do not fret about the need to fertilize it as it can sustain itself on the nutrients available in the soil.
Pruning
Although the Sutera affinis auct. does not require pruning to stay healthy, it's vital to maintain its shape and aesthetic levels. Prune the snowflake by pinching or trimming the stems to keep it bushy and compact, allowing it to produce more flowers. Pruning can be done anytime during the growing season and can be done more frequently to maintain a specific size or shape.
Propagation Methods for Sutera affinis auct.
Sutera affinis auct., commonly known as the trailing bacopa or water hyssop, is a popular trailing plant that is often grown as an ornamental plant. The plant is native to South Africa and is grown in many different regions as an annual or a perennial plant. The plant produces small tubular flowers that come in shades of white or lavender
Propagation through Seeds
Sutera affinis auct. can be propagated through seeds. The seeds should be sown in early spring in a mix of peat moss and perlite. The seeds should be kept moist and warm until they germinate, which usually takes about 7-14 days. The seedlings should be transplanted into separate containers once they have developed their first true leaves. Once they have reached a height of about 4 inches, they can be planted in the garden.
Propagation through Cuttings
Another method of propagating Sutera affinis auct. is through stem cuttings. The cuttings should be taken in early spring or late summer from the current year's growth. The cuttings should be about 4-6 inches long and should be taken from a healthy and disease-free plant. The lower leaves should be removed, and the cutting should be dipped in a rooting hormone. The cutting should be planted in a well-draining rooting medium and kept moist and warm until it develops roots, which usually takes about 4-6 weeks. Once the roots have developed, the cutting can be transplanted into a larger pot or planted in the garden.
Propagation through Division
Sutera affinis auct. can also be propagated through division. This method is best done in early spring when the plant is actively growing. The plant should be carefully removed from the pot or the garden and divided into smaller sections. Each section should have roots and shoots. The sections should be replanted in containers or in the garden, and they should be kept moist until they are established.
Disease and Pest Management for Sutera affinis
Sutera affinis, commonly known as the trailing lobelia or creeping oregano, is a popular ornamental plant that adds a touch of beauty to gardens, hanging baskets, and pots. Like all plants, Sutera affinis is susceptible to diseases and pest attacks that affect its growth and productivity.

The disease appears as a white powdery coating on the leaves, stems, and flowers of the plant, making it look unsightly and weak. To manage this disease, you can prune the affected parts of the plant and dispose of them properly to prevent the spread of spores. You can also apply organic fungicides such as neem oil, potassium bicarbonate, or sulfur dust to control the disease.
2. Rust: Rust is a fungal disease that appears on the leaves of Sutera affinis as yellow or orange spots that turn rusty with time. The disease weakens the plant and reduces its productivity. To manage rust disease, remove the affected leaves and dispose of them properly. You can also apply organic fungicides such as copper-based products or neem oil to control the disease.
3. Leaf Spot: Leaf spot is a bacterial disease that affects the leaves of Sutera affinis, causing small circular spots with yellow or brown margins. The disease weakens the plant, reduces its productivity, and may eventually kill it. To manage the disease, prune the affected leaves and dispose of them properly. You can also apply copper-based fungicides or neem oil to control the disease.
Common Pests
1. Aphids: Aphids are tiny, pear-shaped insects that invade the leaves and stems of Sutera affinis, sucking the sap from the plant and spreading diseases. They appear as clusters of green, yellow, or black insects on the leaves of the plant. To manage aphids, remove them manually or use an insecticidal soap or neem oil to control them. You can also attract beneficial insects such as ladybugs, lacewings, or parasitic wasps to prey on them.
2. Spider Mites: Spider mites are small arachnids that feed on the undersides of the leaves of Sutera affinis, causing them to turn yellow and eventually die. They prefer hot, dry conditions and are common in indoor plants. To manage spider mites, spray the plant with water regularly to keep the leaves moist.
