🔖 Care Tips
It's best to plant seeds in spring or fall. When planting, do not cover them with soil. Maintain a temperature of 18-23°C, and sprouts will appear in 2-3 weeks. Transplant when there are 3-5 leaves for stability. To prevent the plant from spreading, cut the flower stalks after blooming to avoid seed formation. Removing visible plants can also stop or slow down their spread.
🏝️ Habitat Conditions
This plant grows in the temperate regions of Central and South America. It thrives in warm, sunny locations.
🪨 Soil Mix
When planting, it's best to use well-draining soil. Generally, mix 40% potting soil, 20% bark, 20% leaf mold, 10% perlite, and 10% charcoal. However, you can adjust the ratios based on the situation and environment.
👀 Characteristics details

☀️ Light
Place the plant in a well-lit area. However, avoid direct sunlight in midsummer. Use a shade cloth or move it to a shaded area during intense sunlight hours.
💧 Water
Water thoroughly when the soil is dry. Most plants are drought-tolerant, so watering too frequently can lead to overwatering.
🌱 Propagate
It primarily reproduces through seeds. Since it blooms at night, bats or insects pollinate it. Initially, it receives pollen from other flowers, but over time, the pistil bends, allowing self-pollination. This results in strong reproductive ability and easy spread.
💊 Fertilize
Generally not necessary, but using it according to the recommended amount from spring to summer can lead to more vigorous growth.
