Common Names
Scyphogyne calcicola E.G.H.Oliv. is commonly known as the Brazilian Pennyroyal or the itiubense.
Uses
Scyphogyne calcicola E.G.H.Oliv. has some traditional medicinal uses in Brazil, including as a digestive aid and a remedy for coughs and colds. However, there is not much scientific research to support these uses. This plant also has potential ornamental value with its striking purple flowers.
General Appearance
Scyphogyne calcicola E.G.H.Oliv. has lance-shaped leaves that are covered in fine hairs. Its stems are also hairy and branch out near the top, where the bright purple flowers form. These flowers are small and tubular, with five petals that curl back at the tips, creating a star shape. The plant has a slightly minty fragrance when crushed.
Growth Conditions for Scyphogyne calcicola E.G.H.Oliv.
Light: Scyphogyne calcicola E.G.H.Oliv. requires bright indirect sunlight. Direct sunlight can damage its leaves and slow down growth. Growing the plant near a south-facing window is ideal.
Temperature: This plant needs a warm and humid environment. It thrives in temperatures between 20 to 30 degrees Celsius. Temperatures below 15 degrees Celsius can cause the plant's growth to slow down or even stop.
Soil: Scyphogyne calcicola E.G.H.Oliv. prefers well-draining soil that is rich in nutrients. The soil type should be slightly acidic with a pH range between 5.5 to 6.5. A good potting mix for this plant is a mix of peat moss, coarse sand, and perlite.
Water: This plant requires regular watering to keep the soil moist. Over-watering can cause root rot and other plant diseases. Watering once a week is usually sufficient, but you should adjust this depending on the environment and humidity. Ensure that you use room temperature or warm water and pour water evenly throughout the soil.
Fertilizer: Scyphogyne calcicola E.G.H.Oliv. requires regular feeding with a balanced houseplant fertilizer. You should fertilize once every two weeks in the growing season and once a month in the dormant season. Avoid fertilizing during the winter when the plant's growth is slow.
Humidity: Scyphogyne calcicola E.G.H.Oliv. needs high humidity to thrive. You can increase humidity by misting the leaves with water or placing a tray filled with water next to the plant. Alternatively, you can use a humidifier or place the plant in a humid environment such as a bathroom or kitchen.
Cultivation Method
Scyphogyne calcicola is a shrub that grows naturally in rocky outcrops in tropical rainforests. For successful cultivation, the plant requires a similar environment with well-draining, nutrient-rich soil and bright, indirect light. The plant should be propagated from stem cuttings and planted in a pot or directly in the ground in a suitable location.
Watering Needs
Scyphogyne calcicola requires regular watering to keep the soil evenly moist. It is crucial to avoid overwatering as it can cause root rot, which can be detrimental to the plant's health. Ensure that the soil receives adequate drainage to prevent the buildup of excess water in the pot or ground. During the winter season, reduce the frequency of watering to prevent waterlogging and allow the plant to enter dormancy.
Fertilization
Fertilization should be done once every two weeks for Scyphogyne calcicola, using a balanced liquid fertilizer that contains equal proportions of nitrogen, phosphorus, and potassium. The application rates should be in accordance with the manufacturer's instructions to prevent over-fertilization, which can cause the plant to wilt or die. During the winter months, reduce the frequency to once every three to four weeks, as the plant requires fewer nutrients due to dormancy.
Pruning
Scyphogyne calcicola requires minimal pruning, mainly to remove dead or diseased branches. Pruning is best carried out in the spring season, after the winter dormancy period, to encourage new growth. Cut the branches back to the node with a sharp pair of pruning shears to prevent damage to the plant. Avoid pruning during the winter season as it can weaken the plant and make it susceptible to diseases and pests.
Propagation of Scyphogyne calcicola E.G.H.Oliv.
Scyphogyne calcicola E.G.H.Oliv. can be propagated using different methods like seeds, stem cuttings, and division.
Propagation by Seeds
Seeds collected from the plant can be used for propagation. The seeds can be sown in pots or seed trays using a well-draining potting mix. Cover the seeds lightly with soil and place them in a warm and bright area but not under direct sunlight. Water the potting mix regularly to keep it moist. The seedlings will start to emerge after 2-3 weeks.
Propagation by Stem Cuttings
Stem cuttings can be taken from Scyphogyne calcicola E.G.H.Oliv. during the growing season. Choose healthy stems with no flowers or buds. Cut the stem to a length of 10-15 cm (4-6 inches) and remove the lower leaves. Dip the cut end in rooting hormone powder and plant it in a pot filled with well-draining potting mix. Water the potting mix regularly and keep it in a shaded area. The cuttings will root and start to grow after 4-6 weeks.
Propagation by Division
Large clumps of Scyphogyne calcicola E.G.H.Oliv. can be divided into smaller sections and replanted. This method is ideal for mature plants. Gently lift the plant and separate it into smaller sections with a sharp, sterilized knife or pruning shears. Each section should have roots and healthy shoots. Plant each section in individual pots filled with well-draining potting mix and water them regularly. Keep the pots in a shaded area and the plants will start to grow after a few weeks.
Disease and Pest Management for Scyphogyne calcicola E.G.H.Oliv. Plant
Scyphogyne calcicola E.G.H.Oliv. is a relatively hardy plant that is generally pest and disease resistant. However, like any plant, it can still be affected by certain pests and diseases that can cause damage and reduce plant health. Here are some common diseases and pests that might affect the plant and suggestions for managing them:
Diseases
1. Leaf spots: Leaf spots are circular lesions that appear on the leaves of the plant. They can be caused by various fungal or bacterial pathogens. To manage leaf spots, it is important to remove and destroy infected leaves as soon as they are noticed. Additionally, improving plant hygiene by removing fallen leaves and debris from around the plant can help reduce the risk of infection.
2. Powdery mildew: Powdery mildew is a fungal disease that forms a white or grayish powdery layer on the leaves of the plant. To manage powdery mildew, it is important to remove and destroy infected plant material as soon as possible. Good ventilation and air circulation around the plant can also help prevent powdery mildew from forming in the first place.
Pests
1. Spider mites: Spider mites are tiny pests that can cause discoloration and damage to leaves. To manage spider mites, regular monitoring is essential. Infected leaves should be removed and destroyed, and the plant can be treated with insecticidal soap or neem oil spray to control the population.
2. Mealybugs: Mealybugs are small, white, cotton-like pests that often congregate on the undersides of leaves or in leaf axils. To manage mealybugs, infected leaves should be removed and destroyed, and the plant can be treated with an insecticidal soap or neem oil spray.
Overall, maintaining good plant hygiene and regularly monitoring for signs of pest and disease infestation can help keep Scyphogyne calcicola E.G.H.Oliv. healthy and free from major issues.
