There are several methods for propagating Verbena ambrosiifolia:
Seed Propagation
Verbena ambrosiifolia can be easily propagated from seeds. Collect mature seeds from the plant in early autumn when the flowers have dried out. The seeds can be sown outdoors in late fall or early spring. Alternatively, they can be started indoors in late winter and transplanted outdoors in the spring once the danger of frost has passed.
To start seeds indoors, fill a flat or pot with a well-draining seed-starting mix. Sow the seeds on the surface of the soil and cover lightly with a thin layer of soil. Keep the soil moist but not waterlogged and place the flat in a warm, bright location. Germination can be erratic and may take up to 4 weeks.
Cuttings Propagation
Verbena ambrosiifolia can also be propagated from stem cuttings. Take stem cuttings from an established plant in the summer before it blooms. Cut a 4 to 6-inch section of stem just below a leaf node. Strip off the bottom leaves, leaving only a few at the top. Dip the end of the cutting in rooting hormone powder and plant it in a pot filled with a well-draining potting mix. Moisten the soil and enclose the pot in a clear plastic bag to create a humid environment. Once roots have formed, transplant the cutting into a larger pot or into the garden.
Division Propagation
Verbena ambrosiifolia can also be propagated through division. In the fall, dig up an established plant and divide it into sections. Each section should have at least one stem and a good root system. Replant the sections in well-draining soil and water them thoroughly. Keep the soil moist until the plants are established.
With these propagation methods, you can easily propagate and enjoy Verbena ambrosiifolia in your garden or as a potted plant on your patio or balcony.
