General Appearance
Austrosynotis rectirama is a perennial plant that grows to a height of 1.5-2 meters. It has long, slender, and woody stems, which are often greenish in color and can be up to 9mm in diameter. The leaves are simple, alternate, and elliptic in shape, with a smooth surface and a greyish-green color.
The flowers, which bloom from January to August, are small and white, and are arranged in elongated clusters at the tips of the stems. The fruit is a capsule, which contains numerous small seeds.
Light Conditions
Austrosynotis rectirama requires bright indirect sunlight to thrive. It can tolerate some direct sunlight, but not for extended periods, as it can lead to burnt leaves. It is best to place the plant near a window that faces east or west, where it can receive bright diffuse light.
Temperature Requirements
The ideal temperature range for Austrosynotis rectirama is between 18-26 °C (65-80 °F). It can tolerate slightly cooler temperatures but should not be exposed to temperatures below 10 °C (50 °F) or sudden temperature changes. The plant requires a warm and humid environment to grow well, but it is also essential to ensure that there is good air circulation to prevent fungal growth.
Soil and Water Requirements
Austrosynotis rectirama requires well-draining soil that is rich in organic matter. It is best to use a potting mix that contains peat, perlite, and vermiculite. The soil mix should be kept slightly moist, but the plant should not be overwatered. The soil should be allowed to dry out partially before watering to prevent waterlogging. The plant can be watered once a week or when the top inch of soil feels dry.
Fertilizer and Humidity Requirements
Austrosynotis rectirama benefits from regular feeding with a balanced houseplant fertilizer during the growing season. The fertilizer should be diluted to half strength and applied once a month. The plant thrives in a humid environment, so it is beneficial to mist the leaves regularly or use a humidifier if the air is dry. It is also recommended to keep the plant away from cold drafts and heaters, which can cause the air to dry out.
Cultivation
The Austrosynotis rectirama (Baker) C.Jeffrey plant prefers well-drained soils with good fertility and prefers direct sunlight. It is mainly propagated through seeds which should be sown in spring and summer.
The plant can be grown in pots or in open gardens, but it requires some form of support or staking due to its climbing nature. This plant is a good choice for gardeners who want to create a vertical accent in their garden.
Watering Needs
The Austrosynotis rectirama (Baker) C.Jeffrey plant requires moderate watering during its growing period. Watering should be done thoroughly, and the soil should be allowed to dry out slightly before the next watering. Overwatering should be avoided as it can cause root rot.
In the dry season, the plant may require more watering, but care should be taken to avoid waterlogging the soil.
Fertilization
The Austrosynotis rectirama (Baker) C.Jeffrey plant requires regular fertilization during the growing period to maintain its rich foliage and flowering. A balanced fertilizer containing equal parts of nitrogen, phosphorus, and potassium should be used.
Fertilization should be carried out every two weeks, and the fertilizer should be applied to the soil around the plant's base.
Pruning
The Austrosynotis rectirama (Baker) C.Jeffrey plant requires regular pruning to maintain its shape and to prevent it from becoming too leggy. Pruning should be carried out in late winter or early spring.
The plant should be pruned back by about a third of its total height. Any dead, damaged, or diseased stems should also be removed during pruning.
Propagation of Austrosynotis rectirama (Baker) C.Jeffrey
Austrosynotis rectirama (Baker) C.Jeffrey is commonly known as the "Nairobi Bluebell" and is native to Kenya. It is a perennial plant that belongs to the family Campanulaceae.
Propagation methods
The most common method of propagating Austrosynotis rectirama is through seeds. The seeds can be collected from the mature plants after the flowering period. The collected seeds should be cleaned and dried before planting.
Austrosynotis rectirama can also be propagated through stem cuttings. The stem cuttings should be taken from healthy mature plants and should have at least two nodes. The cuttings should be planted in a well-drained soil mix and kept under shade until the roots develop.
Another method of propagating Austrosynotis rectirama is through division. This method is suitable for mature plants that have multiple shoots. The plant should be dug up carefully, and the roots should be gently separated into multiple sections. Each section should have at least one healthy shoot and root system. The divided plants should be replanted in a well-drained soil mix.
Overall, Austrosynotis rectirama is a relatively easy plant to propagate. With proper care and maintenance, the propagated plants can grow into healthy and vibrant specimens.
Disease and Pest Management for Austrosynotis rectirama (Baker) C.Jeffrey
