Propagation of Echium lucidum Lehm.
Echium lucidum Lehm. can be propagated by several methods:
Seed Propagation
Seeds of Echium lucidum Lehm. can be planted in well-draining soil in the spring. The seeds should be sown about 1/8 inch deep and spaced about 9-12 inches apart. The soil should be kept consistently moist until the seeds germinate, which usually takes about 7-21 days. Once the plants are established, they can be transplanted to their permanent location.
Cuttings Propagation
Echium lucidum Lehm. can also be propagated through stem cuttings. Cuttings should be taken in the summer when the plant is actively growing. Cut a 3-4 inch stem tip and remove the lower leaves. Dip the cut end in rooting hormone and plant it in well-draining soil. Keep the soil moist until the cutting roots, which usually takes about 2-4 weeks. Once the cutting has rooted, it can be transplanted to its permanent location.
Division Propagation
Echium lucidum Lehm. can also be divided in the spring or early fall. Dig up the plant and gently separate the roots. Each division should have several stems and a good root system. Replant the divisions in well-draining soil and keep the soil consistently moist until the plants are established.
