Plant Propagation Methods

Centaurea montana ‘Amethyst in Snow’ can be propagated through two methods: sexual and asexual reproduction.

Sexual Reproduction

The sexual reproduction process involves the use of seeds. To propagate the plant sexually, collect the seeds when the flower heads have died back, leaving a brown, dry center.

Let them dry and store them in a cool, dry place until planting time. Sow the seeds in late winter or early spring in moist, well-draining soil.

Cover the seeds with a thin layer of soil, and mist them every few days to ensure they stay moist. Germination time usually takes around two weeks, and once seedlings have established two sets of leaves, they can be pricked out and potted up or transplanted into the garden.

Asexual Reproduction

Asexual reproduction is the process of creating new plants from existing ones, without the use of seeds. The most common types of asexual reproduction for Centaurea montana are division and stem cuttings.

Division

Division is the process of dividing a mature plant’s crown into smaller sections and replanting them. It is best done in the spring, and it is advisable to wait at least four years before dividing the plant to ensure that it is well-established.

Start by digging up the entire plant, and then use a sharp knife or spade to divide the crown into smaller sections. Replant the smaller sections in well-prepared soil, and water them well until established.

Stem Cuttings

Stem cuttings are another way of propagating Centaurea montana. This method involves cutting a stem with a few leaves and planting it in moist soil.

To propagate through stem cuttings, cut a 5-inch (12.7cm) stem from the main plant. Remove the bottom two inches of leaves, and dip the stem’s cut end into rooting hormone, if available.

Plant the stem in moist, well-draining soil, and keep it in a warm but shaded area. The stem cutting should start to root in about four weeks.
