To start growing Mertensia viridis var. cana, you can either plant its seeds or propagate it using stem cuttings. For planting seeds, you need to ensure that the soil is moist at the time of planting. Sow the seeds at a depth of 1/8 inch and keep the soil moist until the seedlings appear. For propagation, take stem cuttings from the plant at the beginning of spring.Watering Needs
Mertensia viridis var. cana is a plant that requires an even amount of moisture throughout the growing season. Make sure that the soil is moist, but not soggy. You can water it deeply once or twice a week, depending on the weather conditions. During the hot summer months, the plant may require more frequent watering.

You can also apply a liquid fertilizer every two weeks during the growing season. The key is to avoid over-fertilization, which can lead to weak growth and poor flowering.Pruning
Mertensia viridis var. cana does not require heavy pruning. However, you can pinch the tips of the plant to encourage the growth of lateral branches. Pruning is also necessary to remove dead or damaged stems and foliage. Deadheading can promote continuous flowering and prevent self-seeding. In conclusion, Mertensia viridis var. cana is a low-maintenance plant that can thrive in a garden with proper care and cultivation. It is essential to maintain an even level of moisture, fertilize with care, and prune as necessary. Follow these guidelines, and you can enjoy the beautiful blue flowers of this plant for years to come.Propagation of Mertensia viridis (A. Nels.) A. Nels. var. cana (Rydb.) L.O. Williams

Cuttings
Propagation through cuttings is also possible with Mertensia viridis var. cana. This involves taking stem cuttings from an established plant and rooting them in a well-draining soil mix. The cuttings should be taken in the late spring or early summer when the plant is actively growing. The cuttings should be dipped in rooting hormone and planted in a soil mixture of perlite and peat moss. The pots should be kept in a warm and humid environment until the roots are well established.
It is important to note that Mertensia viridis var. cana prefers a cool, moist environment and does not do well in hot and dry conditions. Therefore, when propagating this plant, it is essential to keep the soil moist and provide partial shade. With proper care and attention, this beautiful plant can be easily propagated and enjoyed in many gardens and landscapes.
