Liatris graminifolia Willd. var. lasia Fern. & Grisc. can be propagated from both seed and vegetative measures.
Propagation by Seed
Propagation by seed can be achieved by collecting mature seeds in the fall. The seeds should be planted in a well-draining medium in a flat or container with a lid. It is best to plant the seeds at a depth of 1/8 inch and to keep them at a temperature of 70-75 degrees Fahrenheit.
The seeds will germinate in approximately two weeks. Once the seedlings have reached a height of approximately two inches, they can be transplanted into larger containers or directly into the garden.
Propagation by Vegetative Measures
Liatris graminifolia Willd. var. lasia Fern. & Grisc. can also be propagated through division and stem cuttings.
Division should be done in the fall or early spring. Carefully dig up the plant and separate the clump into smaller sections. Each section should have several roots and shoots. Plant each section in a well-draining soil in a location with full sun to partial shade.
Stem cuttings can be taken in the summer when the plant is in full growth. Cut a stem that is approximately four inches long and remove the lower leaves. Dip the cut end into rooting hormone and plant it in a well-draining medium. Keep the cutting moist and in a location with bright, indirect sunlight until roots have formed.
