Propagation of Lipochaeta lavarum (Gaud.) DC. var. scaposa St. John
Lipochaeta lavarum (Gaud.) DC. var. scaposa St. John is a flowering plant species that belongs to the family Asteraceae. It is an endemic species of Hawaii and can be found on the islands of Maui and Moloka?i in dry, rocky areas at elevations ranging from 300 to 1,100 meters above sea level. Propagation of this plant can be done through the following methods:
Propagation from Seeds
This plant species can be propagated from seeds, which can be obtained from mature flower heads. The seeds should be collected when they are mature and dried. After collecting the seeds, they should be stored in a cool and dry place until they are ready for planting. To increase the chances of germination, the seeds can be scarified or soaked in warm water for 12-24 hours before planting. Plant the seeds in well-draining soil and keep the soil consistently moist. Germination can take anywhere from 1-4 weeks.
Propagation from Stem Cuttings
This plant can also be propagated from stem cuttings. Take 3-4 inch long stem cuttings from mature plants. Remove the lower leaves and dip the cut ends in rooting hormone powder. Plant the stem cuttings in well-draining soil and keep the soil consistently moist. Place a plastic bag over the cutting to create humidity and keep the cutting out of direct sunlight. After 3-4 weeks, roots should have formed, and the cutting can be transplanted into a larger container or the ground.
