There are several methods of propagation that can be used to grow new plants of Gentiana quinquefolia L. var. occidentalis Gray:
Seed Propagation
Seed propagation is the most common method of propagating Gentiana quinquefolia L. var. occidentalis Gray. The plant produces tiny, dust-like seeds that are best sown in early spring.

Once planted, the seeds should be kept moist and warm until they germinate, which usually takes up to 60 days. Seedlings should be transplanted into individual pots and grown in a bright, sunny location until they are large enough to be transplanted into the garden.
Division Propagation
Division propagation is another method of propagating Gentiana quinquefolia L. var. occidentalis Gray. This method is best done in early spring or late fall when the plant is in its dormant phase. To divide the plant, carefully dig up the entire plant and gently separate the clumps into smaller sections, ensuring that each section has a good portion of roots and stems. Replant each divided section into a prepared bed, spacing them at least 6 inches apart.
Cuttings Propagation
Cuttings propagation is a less common method of propagating Gentiana quinquefolia L. var. occidentalis Gray but can be successful if done correctly. The best time to take cuttings is during the growing season in early summer. Cut 4-inch pieces from new growth, strip off the lower leaves, and dip the cut ends into rooting hormone. Plant the cuttings in a well-draining potting mix, and keep the soil moist and warm until roots have formed. Once the cuttings have rooted, they can be transplanted into individual pots and grown on until they are large enough to be planted into the garden.
