Ferula persica

Ferula persica is a perennial in the carrot family, Apiaceae. The RHS calls it Persian asafoetida. Its native range runs from Transcaucasus to Iran. Plants For A Future lists Iran, Armenia and Azerbaijan. It grows in temperate regions and occurs on dry slopes. These habitats reach about 6,560 feet [2,000 metres] above sea level. It is not native to Britain or Ireland.

Plants reach about 3.3 feet [1 metre] in height. A long taproot makes moving established plants difficult. The supplied species records give no mature spread. They also give no details of leaves, stems or fruit. Flowers appear from May to July. Each flower has both male and female organs. Insects pollinate the flowers, and the plant is self-fertile. This means it can set seed with its own pollen.

Grow this species in full sun rather than shade. It needs deep, fertile soil with good drainage. It can grow in sand, loam or clay. It also accepts mildly acid, neutral and mildly alkaline soils. The soil may be dry or moist. Plants For A Future lists USDA hardiness zones 6–9. Suggested garden sites include cultivated beds and spots beside walls. East-facing and south-facing walls appear among the listed settings.

Place young plants in their final sites while still small. Their roots do not cope well with disturbance. Sow fresh seed in a greenhouse in autumn. April sowing in a greenhouse is another listed option. Move seedlings into separate pots once large enough to handle. Give young plants a protective mulch for their first winter outdoors. Autumn division is possible, but it risks disturbing the roots. Seed offers a way to avoid dividing established plants.

The plant yields a gum known as sagapenum. The source is uncertain whether this comes from the root. It records traditional use for rheumatism and lower back pain. These records describe use, not proof of medical benefit. Plants For A Future gives it an edibility score of zero. It lists no known food use or known hazards. That does not establish safety for people or pets. The source does not flag weed potential. The supplied evidence names no species-specific pests or diseases.
