Propagation of Coreopsis tripteris L. var. deamii Standl.
There are several methods for propagating Coreopsis tripteris L. var. deamii Standl., including seed propagation, division, and stem cuttings.
Seed Propagation
Coreopsis tripteris L. var. deamii Standl. can be propagated through seeds, which are readily available in nurseries and garden centers. Seeds should be sown in spring or fall in well-draining soil. Plant the seeds at a depth of 1/4 inch, and keep the soil moist until the seedlings emerge, which usually takes 10-14 days. Once the seedlings are established, they can be transplanted into their permanent location.
Division
Coreopsis tripteris L. var. deamii Standl. can also be propagated through division. This should be done in early spring before new growth starts or in fall after the plant has finished flowering. Dig up the entire plant and separate it into smaller clumps with a sharp knife or shovel. Each clump should have several shoots and a good root system. Replant the clumps immediately in their permanent location, and keep the soil moist until they are established.
Stem Cuttings
Coreopsis tripteris L. var. deamii Standl. can also be propagated through stem cuttings taken in late spring or early summer. Take cuttings from the tips of new growth, making sure they are at least 4 inches long and have several sets of leaves. Remove the lower leaves from the cutting and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix, and keep the soil moist until roots form. Once roots have formed, the cutting can be transplanted into its permanent location.
