Overview of Sutera integrifolia
Sutera integrifolia is a flowering plant species that belongs to the family of Scrophulariaceae. This plant is commonly known as the Blue Eyed Grass and is native to South Africa where it grows as a perennial plant. The scientific name of the plant is derived from the Greek word "Sutera", which means "sewing" referring to the hairy stamen thread-like appendages.
Appearance of Sutera integrifolia
The plant features delicate green leaves which are oval-shaped, hairless, and measure up to 2 cm in length. The leaves are clustered around the stem and are arranged oppositely on the stem. The Blue Eyed Grass produces tubular-shaped flowers that resemble small, delicate trumpets. The flowers grow in clusters up to thirteen flowers and exhibit shades of bluish-purple and white, with a yellow center. Sutera integrifolia is characterized by a mass of flowers that blooms in early summer and lasts until the early days of autumn. When growing under appropriate conditions, the plant can reach a height of between 10 to 40 cm.
Uses of Sutera integrifolia
The Blue Eyed Grass is an ornamental horticulture plant species grown in gardens, containers, and hanging baskets. The plant is ideal for filling gaps in borders or using for edging paths in the garden. Sutera integrifolia requires full sun or light shade and well-drained soil that is kept moist throughout the growing season. Overwatering or planting in poorly-drained soil may lead to root rot. The plant can be propagated through seed or by taking cuttings.
The Blue Eyed Grass is also traditionally used in herbal medicine for its anti-inflammatory and pain-relieving properties. The extracts of the leaves and flowers of Sutera integrifolia are used to treat stomach aches, headaches, and skin conditions such as eczema and acne.
Light Requirements
Sutera integrifolia (L.f.) Kuntze prefers bright but indirect light. It can tolerate some direct sunlight during the morning or evening hours but should be protected from strong afternoon sunlight. Inadequate light can result in decreased flowering and leggy growth.
Temperature Requirements
The ideal temperature range for Sutera integrifolia (L.f.) Kuntze is between 18-26°C (65-80°F). It can tolerate temperatures as low as 15°C (59°F) but will struggle in hotter temperatures above 30°C (86°F). It is important to keep the plant away from cold drafts and sudden temperature fluctuations.
Soil Requirements
Sutera integrifolia (L.f.) Kuntze grows well in well-draining soil enriched with organic matter. A pH level between 6.0-7.0 is ideal for optimal growth. The soil should be kept consistently moist but not waterlogged. Overwatering can result in root rot and the death of the plant. Adding a layer of mulch can help retain moisture and regulate soil temperature.
Cultivation Methods
Sutera integrifolia is a hardy plant that can grow in a wide range of soil types and climatic conditions. It thrives in well-drained soil with a pH range of 5.5 to 7.5. The plant must be grown in a location that receives full sun or partial shade.
The plant can be propagated from seeds or cuttings. To propagate from cuttings, take a 4-inch long stem cutting with a few leaves attached and plant it in moist soil. Keep the soil damp and place the cutting in a cool shaded area.
Watering Needs
Sutera integrifolia prefers moist soil but is drought-tolerant. Overwatering can lead to root rot, so it is essential to ensure the soil is well-drained. Water the plant when the soil feels dry to the touch.
It is also important to avoid wetting the foliage, as this can encourage fungal diseases.
Fertilization
Sutera integrifolia is a light feeder and does not require frequent fertilization. However, to promote healthy growth, it is recommended to fertilize the plant with a balanced fertilizer every two to three weeks during the growing season.
Avoid fertilizing the plant during the dormant period as this can lead to excessive growth and reduce flowering.
Pruning
Sutera integrifolia requires minimal pruning. However, to maintain its shape and encourage bushier growth, it can be pruned lightly after flowering.
Deadheading the spent blooms can also promote continuous flowering. In colder climates, the plant can be pruned back to its base and covered with a layer of mulch to protect it from frost damage during winter.
Propagation of Sutera integrifolia (L.f.) Kuntze
Sutera integrifolia (L.f.) Kuntze, also known as Bacopa integrifolia L.f., is a perennial plant that belongs to the Scrophulariaceae family. It is native to South Africa, where it grows in moist areas such as marshes, streams, and riverbanks. Sutera integrifolia is a popular ornamental plant due to its attractive blue or white flowers and its ability to tolerate a wide range of conditions.
Propagation Methods
Sutera integrifolia can be propagated in several ways, including:
1. Seed Propagation:
Seed propagation is the most common method of propagating Sutera integrifolia. The seeds should be sown in a well-draining medium, and kept moist. Germination typically takes 7-14 days. Once the seedlings have developed their first true leaves, they can be potted up into individual containers.
2. Stem Cuttings:
Stem cuttings can be taken from Sutera integrifolia during the spring or summer months. The cuttings should be 5-10 cm long and taken from the tips of the plant. Remove the lower leaves, leaving only one or two pairs of leaves at the tip. Dip the cut end into rooting hormone powder and place the cutting in a well-draining medium. Water the cutting well and keep it in a warm, humid location until roots develop. Once the roots have developed, the cutting can be potted up into individual containers.
3. Division:
Sutera integrifolia can also be propagated through division. Divide the plant during the spring or fall when it is not actively growing. Carefully dig up the plant and divide it into sections, each containing several stems and roots. Replant each section in a well-draining medium and keep it moist until new growth is visible.
