The plant has small, tubular flowers that are usually white or purple and have yellow markings in the throat. The fruit of the plant is a capsule that contains four seeds.
Light Requirements
Blepharis innocua C.B.Clarke var. lancifolia Oberm. prefers a bright light environment with partial shade. It should not be exposed to direct sunlight for prolonged periods, especially during the hot summer months. Indoors, placing the plant near a bright window facing east or west is ideal. Outdoors, it should be planted in areas with partial shade such as under tall trees or shrubs.
Temperature Requirements
Blepharis innocua C.B.Clarke var. lancifolia Oberm. thrives in warm or hot temperatures typically found in tropical regions. The ideal temperature range for healthy growth is between 20°C to 30°C. The plant becomes dormant during winter and does not require any fertilization or watering during this period. Extreme temperatures both hot and cold are detrimental to the plant's growth and survival.
Soil Requirements
The soil requirements for Blepharis innocua C.B.Clarke var. lancifolia Oberm. should be well-draining and rich in organic matter. The soil can be prepared by adding compost or manure to improve its fertility. The plant prefers sandy-loamy soil with a slightly acidic pH ranging from 5.5 to 7.5. Regular watering is necessary to maintain the soil moisture levels. However, care should be taken not to overwater the plant as this may lead to root rot and other related problems.
Cultivation Methods
Blepharis innocua C.B.Clarke var. lancifolia Oberm. prefers a warm, sunny, and dry climate similar to its native habitat in East Africa. It can be grown in a pot or directly in the ground but is well-suited to container cultivation. The planting medium should be fast-draining, with a mix of sand, perlite, and potting soil. A recommended planting time would be in early spring or late autumn.
Watering Needs
Blepharis innocua C.B.Clarke var. lancifolia Oberm. is a drought-tolerant species and requires only modest watering. Its roots should not be sitting in standing water, and the soil should be allowed to dry to a depth of 1-2 inches before watering. During hot, dry spells, additional watering may be necessary. The leaves should not be watered directly to avoid rot and fungal infections.
Fertilization
Blepharis innocua C.B.Clarke var. lancifolia Oberm. does not require extensive feeding and will not benefit from heavy fertilizer application. The plant can be fed every two to three weeks during the growing season with a balanced or low-nitrogen fertilizer diluted to half the recommended strength. Fertilizing should be stopped in autumn and winter as the plant enters a period of dormancy.
Pruning
Blepharis innocua C.B.Clarke var. lancifolia Oberm. needs little pruning other than the occasional removal of damaged or diseased stems. To encourage new growth, pinch back the tips of each stem once or twice during the growing season. Generally, this plant maintains a compact, bushy form without heavy intervention.
Propagation of Blepharis innocua C.B.Clarke var. lancifolia Oberm.
Blepharis innocua C.B.Clarke var. lancifolia Oberm. can be propagated through various methods. Some of the common propagation methods are:
Seed Propagation
Seeds can be collected from matured fruits and sown directly into the soil. It is important to note that the seeds should be cleaned and soaked in water overnight prior to planting. The soil mix for planting the seeds should consist of sand, loam, and compost in the ratio of 1:1:1. The seeds should be sown at a depth of 2-3 cm and watered regularly. The seeds take about 2-3 weeks to germinate and need to be kept moist during this period.
Cutting Propagation
The Blepharis innocua C.B.Clarke var. lancifolia Oberm. can be propagated through stem cuttings as well. This method is less common and not as successful as seed propagation. Stem cuttings can be taken from mature plants and planted in well-draining soil. The cuttings should be dipped in rooting hormone powder before planting. It is essential to keep the soil moist and covered with plastic to maintain high humidity. It takes about 6-8 weeks for the cuttings to root and establish.
Division Propagation
Division propagation involves dividing the rootball of an established plant into smaller sections and planting each in individual containers. This method can only be done for mature plants that have produced multiple stems. Care should be taken not to damage the roots during the division process. The plants should be planted in well-draining soil and watered regularly to maintain moisture levels.
Disease and Pest Management for Blepharis innocua C.B.Clarke var. Lancifolia Oberm.
Blepharis innocua C.B.Clarke var. lancifolia Oberm. is a hardy plant that can tolerate a wide range of growing conditions. However, like all plants, it is susceptible to various diseases and pests. Here are some common problems and ways to manage them:
Diseases
Root rot: This is a common fungal disease that affects many types of plants, including Blepharis innocua var. lancifolia. Symptoms include yellowing leaves, wilting, and stunted growth. To manage root rot, remove infected plants and debris from the soil. Avoid overwatering and ensure good drainage. Plant in well-draining soil and avoid planting in areas that are prone to flooding.
Powdery mildew: Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves and stems of the plant. To prevent powdery mildew, ensure good air circulation around the plant and avoid overhead watering. Apply a fungicide if necessary.
Leaf spot: Leaf spot is a fungal disease that appears as brown spots on the leaves and can cause them to drop prematurely. To prevent leaf spot, avoid overhead watering, remove infected leaves, and apply a fungicide if necessary.
Pests
Spider mites: Spider mites are tiny pests that feed on the leaves of the plant, causing yellowing and eventually death. To manage spider mites, remove infected leaves and apply a miticide.
Aphids: Aphids are small insects that feed on the sap of the plant, causing stunted growth and distorted leaves. To manage aphids, spray the plant with a strong jet of water to dislodge them or apply an insecticide.
Thrips: Thrips are tiny insects that cause damage to the leaves by sucking the sap from them. To manage thrips, remove infected leaves and apply an insecticide.
By taking preventive measures, detecting diseases and pests early, and taking appropriate action, you can keep your Blepharis innocua C.B.Clarke var. lancifolia Oberm. healthy and strong.
