- 1 Cut a healthy semi-hardwood stem 15-20 cm long
- 2 Remove lower leaves, keeping 2-3 at the top
- 3 Dip the base in rooting hormone powder
- 4 Plant in moist, well-draining propagation mix
- 5 Keep in a shaded, humid spot for 4-6 weeks
Materials needed:
Seed Sowing
Germination is irregular. Fresh seeds have higher germination rates.
- 1 Collect mature seeds from dried pods
- 2 Sow in a tray with moist, fine substrate
- 3 Cover lightly with a thin layer of substrate
- 4 Keep in a warm, bright location
- 5 Transplant when seedlings reach 10 cm

What Diseases Commonly Affect Flame Vine?
TLDR: Flame Vine is susceptible to 6 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
Joy, celebration, and tropical exuberance. In Brazil, its orange blooms are associated with the June festivities.
