Brassavola flagellaris Plant Care

Brassavola flagellaris (Brassavola venosa) belongs to the Orchidaceae family within the Brassavola genus. Brassavola flagellaris is native to Mexico, Central America, the West Indies, and northern South America. Brassavola flagellaris is also known as Lady of the Night Orchid.

Brassavola flagellaris displays an epiphytic, clumping orchid growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Brassavola flagellaris produces fragrant white or greenish-white flowers with long, narrow petals.

Leaf size: approximately 4 inches.

Brassavola venosa requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Brassavola flagellaris thrives in bright indirect to dappled sunlight. Avoid placing Brassavola flagellaris in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Brassavola venosa grows best at temperatures of 60–80°F. Brassavola flagellaris prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining orchid mix with bark, sphagnum moss, and perlite. Good drainage is essential for Brassavola flagellaris to prevent waterlogging, which leads to root rot and fungal issues.

Feed Brassavola flagellaris every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

Repot every 2-3 years after flowering. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Brassavola flagellaris can be propagated through division, back bulbs, keiki propagation. Similar propagation techniques also apply to appendiculata brassavola plant care, which shares the same genus.
