Learning how to propagate verbena is useful for the gardener who does not want to purchase many new plants. A single verbena plant can produce multiple plants for the next season. Verbena propagates best with cuttings, although layering and seed propagation are also possible. Newly propagated verbena plants are ideal for rock gardens, boarders, groundcovers or filling voids in an ornamental garden.
How to Take Verbena Cuttings
The best time to take Verbena cuttings is late spring because the young plant material readily develops roots. Summer cuttings are often successful as well, and more resistant to wilting, but they are slower to root.
Use sharp scissors to cut the stem at a 45-degree angle, just below a node. Cut current season growth, avoiding woody material. Remove any blooms from the cut stem; this will allow the plant to devote more energy to growing new roots.
How to Propagate Verbena through Cuttings
Verbena will root in water or rooting medium. Rooting hormone is not necessary. To root in water, put the cuttings in a container with a couple inches of water, and place it in indirect sunlight. A clear container will allow visual observation of developing roots.
Alternatively, cuttings will root in good quality potting soil as a rooting medium. Place the potting soil, loosely packed, in a small container. Poke a hole in the soil and plant the stem. Water it daily to keep the soil moist but not soggy. Keep cuttings out of direct sunlight until they are well rooted to make them less susceptible to wilting.
Check the cuttings weekly for roots. If you are using rooting medium, check for root development by gently tugging on the stems. Once sufficient roots develop, plant the new Verbena plants in the garden or a container.
