Nigella tenuiflora Plant Care

Nigella tenuiflora (Nigella tenuiflora) belongs to the Ranunculaceae family within the Nigella genus. Nigella tenuiflora is native to North Africa, central, southern and eastern Europe, the Caucasus region, and the Middle East as far as Iran, and has gone extinct in Switzerland and Crete.

Nigella tenuiflora displays an upright, branching herb growth habit, reaching up to 1.5 ft tall with a spread of approximately 0.5 ft. Nigella tenuiflora produces delicate, star-shaped flowers in shades of blue, pink, or white.

Leaf size: approximately 2 inches.

Nigella tenuiflora requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Nigella tenuiflora thrives in full sun to partial shade.

Nigella tenuiflora grows best at temperatures of 60–75°F. Nigella tenuiflora prefers humidity levels of 40–60%.

Well-draining, sandy loam with added organic matter. Good drainage is essential for Nigella tenuiflora to prevent waterlogging, which leads to root rot and fungal issues.

Feed Nigella tenuiflora every 4 months 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 annually in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Nigella tenuiflora can be propagated through seeds. Similar propagation techniques also apply to field nigella plant care, which shares the same genus.
