Appearance
Calla plants are herbaceous perennials that grow up to 2-3 feet tall. They have large, glossy leaves that are usually green, but can also be variegated. The flowers grow on long stems and are shaped like a trumpet, with a yellow spadix (the central spike) surrounded by a colorful spathe (the petal-like structure). The spathe can be white, pink, yellow, or red, and may have a glossy or matte texture. Calla flowers bloom in late spring or early summer and can last for several weeks.
Care Guide
Calla plants are relatively easy to care for and can be grown both indoors and outdoors. Here are some tips for taking care of your Calla plant:
- Water: Calla plants require consistently moist soil, but not waterlogged. Water your plant regularly, especially during the growing season, and reduce watering in the winter.
- Fertilization: Use a balanced fertilizer every two weeks during the growing season to promote healthy growth and flowering.
- Soil: Calla plants prefer well-draining soil that is rich in organic matter. A soil pH of 6.0 to 6.5 is ideal.
- Sunlight: Calla plants prefer bright, indirect sunlight. Avoid direct sunlight, as it can scorch the leaves.
- Hardiness Zones: Calla plants are hardy in USDA zones 8-10. In colder zones, they can be grown as annuals or kept indoors during the winter.
Common Pests & Diseases
Calla plants are generally resistant to pests and diseases, but they can still be affected by certain issues. Here are some common problems to watch out for:
- Spider Mites: These tiny pests can cause yellowing and browning of the leaves. They can be controlled with insecticidal soap or neem oil.
- Fungal Diseases: Calla plants can be susceptible to fungal diseases, such as root rot and leaf spot. These can be prevented by providing good drainage and avoiding overhead watering.
- Leaf Burn: Calla plants can develop leaf burn if they are exposed to too much direct sunlight. Move your plant to a shadier spot to prevent this issue.
Habitat
Calla plants are native to southern Africa, where they grow in wetlands and along streams and ponds. They prefer moist soil and can tolerate partial shade. Calla plants have been introduced to other parts of the world and can now be found growing in a variety of habitats, including gardens, parks, and natural areas.
