Cultivation Methods for Lomatium Bicolor (S. Wats.) Coult. & Rose var. Leptocarpum (Torr. & Gray) Schlessman
Lomatium bicolor var. leptocarpum is a herbaceous perennial plant that grows well in temperate regions with hot, dry summers and cold, humid winters. It is a low maintenance plant and can be grown from seeds or root cuttings.
Plant seeds in spring or fall in well-drained soil, 1/8 inch deep and 12 inches apart. Cover the seeds with soil and water them lightly, then keep the soil moist until germination. Thin the seedlings to 6-8 inches apart once they reach a few inches tall.
For root cuttings, take 2-3 inch long cuttings in early spring or fall. Plant them in potting soil and keep them moist until they develop roots, then transplant them to their permanent location in well-drained soil.
Watering Needs for Lomatium Bicolor (S. Wats.) Coult. & Rose var. Leptocarpum (Torr. & Gray) Schlessman
Lomatium bicolor var. leptocarpum is drought-tolerant and does not need to be watered frequently. Water the plant deeply once a week during the growing season, and reduce watering in the fall and winter when the plant is dormant.
Avoid overwatering, as this can lead to root rot. Allow the soil to dry out between watering, and do not water again until the top inch of soil is dry.
Fertilization for Lomatium Bicolor (S. Wats.) Coult. & Rose var. Leptocarpum (Torr. & Gray) Schlessman
Lomatium bicolor var. leptocarpum typically grows in nutrient-poor soils and does not need fertilizer. However, if the soil is particularly poor, or if the plant appears weak or stunted, a light application of all-purpose fertilizer can be applied in the spring.
Do not fertilize in the fall or winter, as this can stimulate new growth that is vulnerable to frost damage.
Pruning for Lomatium Bicolor (S. Wats.) Coult. & Rose var. Leptocarpum (Torr. & Gray) Schlessman

Propagation of Lomatium bicolor var. leptocarpum
Lomatium bicolor var. leptocarpum is a perennial herb that belongs to the Apiaceae family. This flowering plant is native to western North America and can be found in different habitats, including rocky areas, dry slopes, and sagebrush scrub. Propagation of this plant can be done either by seed or by division.
Propagation by Seed
The most common propagation method for Lomatium bicolor var. leptocarpum is through seed. The seeds of this plant are small and should be collected when they are mature, dry, and brown. Then, the seeds should be stored in a cool, dry place until planting. Before planting, the seeds need to be scarified, which means their hard seed coat needs to be scratched or nicked to enhance germination.
The best time to plant Lomatium bicolor var. leptocarpum seeds is in the fall or early winter. The seeds should be lightly covered with soil and kept moist until they germinate, which may take several weeks to several months. Once germinated, the seedlings can be transplanted to their permanent location.
Propagation by Division
Propagation of Lomatium bicolor var. leptocarpum can also be done through division. This method involves digging up the plant's root system and dividing it into smaller sections, each with its own shoot and root system. Division should be done in the spring before the plant starts growing. The divided sections should be replanted and watered well until established.
It is important to note that Lomatium bicolor var. leptocarpum has a taproot, which makes division difficult and can result in low survival rates.
