Jovellana
Contents
Description
Jovellana is a genus of flowering plants native to the southern parts of South America, specifically Chile and Argentina. The plants are named after the Spanish botanist, Antonio Jovellanos. Jovellanas are known for their beautiful and unique trumpet-shaped flowers that come in a range of colors, including purple, pink, and white. These flowers bloom in the spring and summer months and can last for several weeks. Jovellanas are members of the Gesneriaceae family, which includes many other popular houseplants such as African violets and gloxinias.

Appearance
Jovellanas are small shrubs that can grow up to 2-3 feet tall. The leaves are dark green and glossy, and can be either oval or heart-shaped. The flowers are the standout feature of this plant, with their trumpet-like shape and vibrant colors. The flowers can be up to 2 inches in diameter and are often covered in fine hairs. Some species of Jovellana also have a sweet, pleasant fragrance.
Care Guide
When it comes to caring for Jovellanas, it’s important to mimic their natural habitat as much as possible. Here are some tips on how to care for your Jovellana:
- Water: Jovellanas prefer to be kept consistently moist, but not waterlogged. Water thoroughly when the top inch of soil feels dry to the touch.
- Fertilization: Use a balanced fertilizer every two weeks during the growing season (spring and summer).
- Soil: Use a well-draining, nutrient-rich soil that is slightly acidic (pH 5.5-6.5).
- Sunlight: Jovellanas prefer bright, indirect light. Avoid direct sunlight, as it can scorch the leaves.
- Hardiness Zones: Jovellanas are hardy in zones 9-11. If you live in a colder climate, consider growing your Jovellana as a houseplant.
Common Pests & Diseases
Jovellanas are relatively pest and disease-resistant, but they can still fall victim to a few common issues. Here are some things to watch out for:
- Aphids: These small, pear-shaped insects can suck the sap from Jovellana leaves and cause them to yellow and curl. Use an insecticidal soap to control aphids.
- Botrytis: This fungal disease can cause gray or brown spots on Jovellana leaves and flowers. Remove any affected foliage and improve air circulation around the plant to prevent further spread.
- Root Rot: Overwatering can lead to root rot, which causes the roots to turn brown and mushy. To prevent this, make sure the soil is well-draining and allow the top inch of soil to dry out between waterings.
Habitat
Jovellanas are native to the southern parts of South America, where they grow in cool, damp forests and along streambanks. They prefer cool temperatures (between 60-75°F) and high humidity. In their natural habitat, Jovellanas can grow to be quite large, but as houseplants, they tend to stay smaller.
Question and Answer
