Common names

Sutera atrocaerulea Fourc. is commonly referred to as Blue Eyed Grass or Blue Eyed African Daisy due to its striking blue flowers with yellow centers. Additionally, it is also known as the trailing lobelia because of its trailing stems, which can grow up to 1.5 meters in length.

Uses

Sutera atrocaerulea Fourc. is a popular ornamental plant in gardens and landscapes. It is frequently grown in hanging baskets, containers, or as a groundcover. The plant's trailing habit allows it to cover large areas and suppress weed growth. Moreover, it is a stunning display when planted in mass groupings. This plant thrives in full sun to light shade and prefers moist, well-drained soils for optimal growth.

General appearance

The Sutera atrocaerulea Fourc. plant has a trailing growth habit with stems that can grow up to 1.5 meters in length. The leaves are small, oval-shaped, and a bright green color. They are arranged alternatively along the stem. The flowers are solitary and can appear throughout most of the year, but they are most abundant in the spring and summer months. Each flower measures about 2.5 cm in diameter, and it has five petals with a deep blue color and a yellow center.

The plant's trailing stems make it a popular choice for hanging baskets and container gardens, where the stems can spill over the sides. When planted in mass groupings, it provides a beautiful carpet-like effect, blooming in abundance. Its striking blue flowers are sure to bring attention to any garden or landscape. Sutera atrocaerulea Fourc. is also beneficial to bees, butterflies, and other pollinators due to its nectar-rich flowers.

Light Requirements

Sutera atrocaerulea requires bright but indirect light for optimal growth. Direct sunlight can burn the leaves of the plant and cause it to wilt.

Temperature Requirements

The ideal temperature range for the growth of Sutera atrocaerulea is between 18°C to 24°C (65°F to 75°F). The plant cannot tolerate extremely high temperatures or sudden temperature changes, which can cause stress and damage to the leaves.

Soil Requirements

The plant prefers well-draining soil that is rich in organic matter. A mixture of peat moss, sand, and perlite is ideal for Sutera atrocaerulea. The soil pH should be slightly acidic, between 5.5 to 6.5. It is important to avoid overwatering, as the plant can be susceptible to root rot.

Cultivation

Sutera atrocaerulea Fourc., also known as Blue River, is a tender perennial plant that thrives in warm temperatures. It can be grown in containers or in garden beds, as long as it is sheltered from strong winds.

The plant prefers full to partial sun in well-drained soil that is rich in organic matter. It can be propagated from stem cuttings taken in the spring.

Watering Needs

Regular watering is essential for the growth and health of Sutera atrocaerulea Fourc. This plant requires moderate watering, meaning the soil should be kept moist but not waterlogged.

During the summer months, it may need to be watered more frequently to avoid drought stress. However, it is important not to overwater, as this plant is susceptible to root rot.

Fertilization

To encourage healthy growth and blooming, Sutera atrocaerulea Fourc. benefits from regular fertilization. This should be done every two weeks during the growing season, using a balanced fertilizer that is high in phosphorus.

It is important to avoid over-fertilizing, as this can cause damage to the plant and make it more susceptible to pests and diseases.

Pruning

Sutera atrocaerulea Fourc. benefits from regular pruning to maintain a compact and bushy shape. This should be done at the end of the growing season, removing any dead, damaged, or diseased plant material.

It is also possible to pinch back the tips of the stems throughout the growing season to encourage branching and more abundant flowering.

Propagation of Sutera atrocaerulea Fourc.

Sutera atrocaerulea Fourc. is commonly known as the blue satin flower and is a perennial herbaceous plant that is native to South Africa. You can propagate the plant easily by following some simple steps.

Propagation by Seeds

The easiest way to propagate Sutera atrocaerulea Fourc. is by using seeds. The best time to do this is in spring, just before the growing season begins. Here are the steps to follow:

1. Start by filling a seed tray with a good quality compost mix.
2. Add a little water to the tray to moisten the compost mix.
3. Sow the seeds on top of the compost mix and cover them lightly with more mix.
4. Place the seed tray in a warm and bright location where the temperature is around 70°F.
5. Keep the compost mix moist, but be careful not to overwater it.
6. The seeds should germinate in 14 to 21 days.
7. Once the seedlings have grown a little larger, you can transplant them into individual pots and keep them in a sunny location until they are ready to be planted outdoors.

Propagation by Cuttings

You can also propagate Sutera atrocaerulea Fourc. using stem cuttings. The best time to do this is in spring or early summer. Here are the steps to follow:

1. Select healthy stems from the parent plant and make a clean cut just below a leaf node.
2. Remove any flowers or buds from the stem.
3. Dip the cut end of the stem in rooting hormone powder.
4. Fill a pot with a good quality compost mix and make a hole in the center.
5. Insert the cutting into the hole in the compost and gently firm the mix around it.
6. Water the compost mix thoroughly.
7. Place the pot in a warm and bright location where the temperature is around 70°F.
8. Keep the compost mix moist, but be careful not to overwater it.
9. The cutting should root in 4 to 6 weeks and can be transplanted into a larger pot or outdoors.

Disease and Pest Management for Sutera atrocaerulea Fourc.

Sutera atrocaerulea Fourc., commonly known as Bacopa, is a great outdoor plant for garden lovers as well as for indoor decoration. Bacopa is generally tolerant of pests and diseases, but it may occasionally be affected by some common problems.

Diseases

The main disease affecting Sutera atrocaerulea Fourc. is fungal infection. Fungi tend to grow in moist environments, which can damage Bacopa plants. To prevent fungal infection, it is essential to provide adequate ventilation and avoid over-watering. Cut off any infected parts of the plant and dispose of them immediately. To prevent the disease from spreading, apply a fungicide to the plant leaves and soil as a preventive measure.

Pests

Bacopa plants are affected by a few pests, including aphids and spider mites. Aphids are small, soft-bodied insects that feed on the plant's sap, causing leaves to curl and yellow. Spider mites are tiny, spider-like pests that feed on the plant's water-storing cells, drying out the plant and causing leaf wilt.

Bacopa plants can be treated with insecticidal soap or neem oil, which will kill the pests as well as any eggs they've laid. Alternatively, using a strong stream of water to blast both mites and aphids off the plant can help control the problem.

Regularly inspecting the plant and regularly removing any infected or pest-ridden plant parts can help prevent pests from becoming a significant problem and significantly reduce the need for pesticides.

With proper care and management, Sutera atrocaerulea Fourc. can be a beautiful and trouble-free plant for any garden or indoor setting.
