Propagation by Seeds
Seeds of Dicoria canescens Gray ssp. brandegeei can be collected during the summer months after the plant has bloomed and the flowers have turned into fluffy balls of seeds. The seeds can then be sown directly in the soil about an inch deep where they will be left undisturbed until they germinate. The ideal time to sow the seeds is in late summer or early fall before the first frost. The soil should be well drained and slightly alkaline with a pH between 7.0 and 8.0. The seeds should germinate within two to three weeks.

Remove all the leaves except for the top few and dip the cut end in a rooting hormone. Plant the cutting about an inch deep in a pot filled with well-draining soil. The pot should be placed in a well-lit area but not directly exposed to sunlight. The plant should start rooting within two to three weeks. After the roots have formed, the plant can be transplanted outdoors into well-draining soil with a pH between 7.0 and 8.0.
