Origin
Zantedeschia chloroleuca Engl. & Gilg, also known as the yellow arum lily, is a plant species native to South Africa, specifically the Eastern Cape Province.
Common Names
Besides its scientific name and the yellow arum lily, this plant is also known as the green and white arum lily, yellow calla lily, and the South African flag lily, due to its flowers' resemblance to the colors of the country's flag.
Uses
The Zantedeschia chloroleuca plant has both ornamental and medicinal uses. Its beautiful blossoms make it a popular choice for gardens, cutting, and floral arrangements. Meanwhile, traditional healers in South Africa use different parts of the plant for various medical purposes, such as treating diarrhea, stomach pains, and irritations.
General Appearance
Zantedeschia chloroleuca is a perennial herb that usually reaches up to two feet in height. It has a smooth stem and long, arrow-shaped leaves with prominent veins that can grow up to 8 inches in length. The flowers bloom on long stalks and have a bright yellow spathe and spadix, which can grow up to 5 inches long. The plant fruit is a green berry-like capsule containing several small seeds.
Light Requirements
Zantedeschia chloroleuca is a plant that thrives in bright, indirect sunlight. Direct sunlight can cause leaf burn, so it is important to place it in a spot where it receives bright light but not direct sun. It is also possible to grow this plant under fluorescent lights. Artificial light should be placed at a distance of at least six inches from the plant.
Temperature Requirements
Zantedeschia chloroleuca grows well in temperatures between 18°C to 29°C. The plant is sensitive to extreme temperatures and should be kept away from cold drafts and heaters. High humidity levels are beneficial for growth, so it is recommended to keep the plant in a room with a humidifier or place a tray of water near the plant to increase humidity levels.
Soil Requirements
The soil for Zantedeschia chloroleuca should be well-draining and rich in nutrients. A soil pH of 6.0 to 6.5 is ideal for this plant. A mixture of peat moss, perlite, and sand in equal parts works well. Ensure that the soil remains moist but not waterlogged. Watering the plant when the soil is dry to the touch is recommended.
Cultivation Methods
Zantedeschia chloroleuca, commonly known as the Green Goddess Calla Lily, is a wonderful addition to any garden. For optimal growth, it is recommended to plant Zantedeschia chloroleuca in a well-draining soil mixture with a pH level of 6.5 to 7.0. The plant prefers partial to full shade, making it perfect for underplanting or adding texture to the borders.
Watering Needs
Proper watering is crucial to the growth and development of Zantedeschia chloroleuca. A consistent moist soil mixture is preferred, but waterlogging should be avoided. The plant requires more frequent watering during the growing season and less frequently during winters. The top 2 inches of soil should be checked for water retention before watering to prevent over-watering or underwatering.
Fertilization
During the growing season, the plant should be fertilized every two weeks with a diluted complete fertilizer. Fertilizing should be done after watering the plant to prevent burning the roots. The fertilizer should contain elements like nitrogen, phosphorus, and potassium to aid growth and flowering.
Pruning
Zantedeschia chloroleuca requires regular pruning to prevent the buildup of old, yellowing leaves or spent blooms that can affect its growth. The faded flowers should be cut off once they start browning or start wilting as this allows the plant to focus its energy on new blooms. The pruning should be done using sterilized pruning shears to avoid the transmission of diseases.
Propagation of Zantedeschia chloroleuca Engl. & Gilg
Zantedeschia chloroleuca Engl. & Gilg, commonly known as the green and white arum lily or the spotted arum, can be propagated through various methods:
Seed Propagation
The most common method of propagation for Zantedeschia chloroleuca is through seeds. Collect fully ripe seeds from the parent plant. The seeds are available once the capsule opens up, and the berries are fully ripe. Spread the seeds on the surface of seed-raising mix in a pot or seed tray. The seeds require light to germinate, so avoid covering them with a mix. Keep the mix moist and place the pot or seed tray in a warm, partially shaded area. Germination usually takes place within 1-2 weeks. Once the seedlings are strong enough to handle, transplant them into larger containers containing potting mix.
Division
Another propagation method for Zantedeschia chloroleuca is through division. Dig out the parent plant during its dormant season and carefully cut the tubers into smaller pieces, ensuring that each piece has at least one bud. Plant each tuber in separate pots filled with potting mix and keep them in a warm, partially shaded area. Water the pots regularly and be patient as the new plants start to grow.
Cuttings Propagation
Propagation of Zantedeschia chloroleuca is also possible through cuttings. Take a cutting of about 7 cm from the parent plant, ensuring that it includes a small portion of the tuber and a growing point. Dip the cut end of the cutting in rooting hormone and plant it vertically into a small pot filled with potting mix. Cover the pot with a transparent plastic bag to maintain high humidity levels and keep the pot in a warm, shaded area. Water the pot frequently to ensure that the potting mix remains moist. Once new growth appears, remove the plastic bag and transplant the plant to a larger pot when it outgrows the small one.
Disease and Pest Management for Zantedeschia Chloroleuca Engl. & Gilg
Zantedeschia Chloroleuca Engl. & Gilg, commonly known as the green and white arum lily, is a plant species that belongs to the Araceae family. Like any other plant, it is susceptible to many diseases and pests. To grow healthy plants, it is crucial to manage these adversities. Here are some common diseases and pests that may affect the plant and ways to manage them.
Diseases
1. Soft Rot
Soft rot is a disease that occurs due to bacterial infection. The leaves and stems of the plant become slimy, dark, and mushy. To manage and avoid soft rot, remove and destroy infected plants. Disinfect the tools and equipment used on the plant and avoid overwatering.
2. Rust
Rust is a fungal disease that causes yellow spots on the upper leaves and reddish-brown spots on the lower leaves. You can manage rust by removing and destroying infected plants and avoid watering plants on the leaves or flowers.
Pests
1. Aphids
Aphids are insects that suck the sap of the plant. The presence of these insects is noticeable by the sticky honeydew they excrete. To manage aphids, use horticultural oils, spray with soapy water, or use insecticidal soap. Additionally, remove and destroy infected plants.
2. Spider Mites
Spider mites are tiny insect pests that can suck plant sap and cause the leaves to turn yellow and curl. To manage spider mites, use horticultural oils, spray with soapy water, or use insecticidal soap. Also, regularly clean the leaves of the plant, avoid using fertilizers high in nitrogen, and check the soil moisture regularly.
Overall, managing diseases and pests that can affect Zantedeschia Chloroleuca helps to grow healthy and productive plants. By taking the necessary steps to manage these adversities, you can enjoy the beauty of your green and white arum lily plants.
