Plant Needs
Sunlight
Requires full sun to thrive in its native meadow habitats.
Watering
Requires moist soil in early spring, but must dry out completely during summer dormancy.
Temperature
Tolerates cold, wet winters and hot, dry summers typical of its native range.
Characteristics
- Leaves: Basal, finely dissected into linear segments, glabrous, appearing fern-like;
- Flowers: Small, pale yellow to yellowish-white, clustered in compound umbels at the end of slender stalks;
- Stem: Slender, mostly leafless, arising from a deep taproot;
- Fruit: Oblong to elliptic schizocarps with narrow lateral wings.
Care Guide
Watering
Keep moist in spring; cease watering entirely in summer when dormant.
Fertilization
Apply a very light, natural top-dressing if soil is extremely poor.. Adapted to nutrient-poor, heavy clay soils; avoid rich fertilizers.
Eggshell powder：Crush clean, dry eggshells into a fine powder and sprinkle sparingly around the base in early spring to support root health without over-fertilizing. Avoid high-nitrogen materials.Pruning
- Allow foliage to die back naturally in early summer to return energy to the taproot;
- Do not cut green leaves;
- Remove dead debris only in late autumn to prevent fungal issues.
Toxicity

Pets & Humans
Pets: No known toxicity to cats per general Apiaceae (Lomatium) records.
Humans: Generally considered non-toxic, though foraging wild Apiaceae is highly discouraged due to deadly look-alikes.
Garden Uses & Culture
Culture: A flagship species for the conservation of the highly endangered vernal pool and wet meadow ecosystems of the Rogue River Valley in Oregon.
Usage: Primarily grown for ecological restoration and native plant conservation.
