Propagation of Cardamine tenella (Pursh) O.E. Schultz var. covilleana O.E. Schultz
Cardamine tenella (Pursh) O.E. Schultz var. covilleana O.E. Schultz, commonly known as Coville's bittercress, is a small plant species in the family Brassicaceae. It is native to North America and can be propagated through various methods.
Seed propagation
The primary method of propagation for Cardamine tenella var. covilleana is through seed. The seeds can be sown directly into the ground in early spring or late fall. They should be planted at a depth of 1/8 to 1/4 inch and spaced 6 to 8 inches apart. The soil should be moist, with good drainage, and in partial to full shade.
Division propagation
Another propagation method for Cardamine tenella var. covilleana is through division. This is done by separating the rhizomes from the parent plant and planting them in another location. The division should take place when the plant is dormant, which is typically in early spring or late fall.
Cuttings propagation
Cuttings are not a common method of propagation for Cardamine tenella var. covilleana, but it can be done. Take a stem cutting from a healthy, mature plant and place it in a rooting hormone. Then plant it in a well-draining soil mixture and keep it moist until roots develop. This method has a lower success rate than seed or division propagation.
No matter what propagation method is used, Cardamine tenella var. covilleana requires consistent moisture and some shade to thrive. With proper care, it can produce an abundance of small, delicate white flowers in the spring.
