Propagating the Carex oshimensis ‘Everillo’ can be achieved using two main methods: asexual and sexual reproduction.

These methods yield new plants that are genetically identical or not identical to their parent. Depending on your preferences and the number of plants desired, you can choose the propagation method that suits your goals.

Asexual Reproduction

The process of asexual propagation involves using a part of the parent plant to create a new individual. This part of the plant can be a leaf, stem, or root.

One of the easiest ways of propagating the Carex oshimensis ‘Everillo’ using asexual propagation is by division. Divide the parent plant in the early spring before it starts growing.

Gently dig out the parent plant from the soil and separate its clumps, ensuring each clump has enough roots intact. Replant each clump using a well-draining, high-quality soil mix to prevent overwatering.

Cut back any excessive foliage to reduce stress in the plant and improve its recovery rate. Clean up the resulting clumps to ensure that they will grow vigorously.

Another method of asexual propagation is through plantlets or runners. This method involves allowing the plant to produce offsets or miniature plants that grow from the parent plant’s base.

When the offsets are mature, remove them from the parent plant and place them in individual pots or plant them directly into the garden. Be sure to use well-draining soil and don’t bury the new plant too deeply in the ground.

Sexual Reproduction

The process of sexual reproduction involves pollination, either by human intervention or naturally by wind and insects. After pollination, the plant produces seeds, which grow into new plants that may differ from the parent in terms of color, shape, and other characteristics.

Unlike asexual reproduction, sexual reproduction allows for genetic variations. To propagate Carex oshimensis ‘Everillo’ using sexual reproduction, begin by selecting healthy, mature plants for fertilization.

After the plants bloom, their small, greenish seed heads appear. Wait until these seed heads mature and develop brown or dark-colored seeds before harvesting.

Collect the seeds and place them in a well-lit, warm area to dry for a few days. After the seeds dry out, sow them in poor, well-draining soil and cover them with a thin layer of sand.

Water the seeds carefully, using a spray bottle or watering can with a fine nozzle to avoid overwatering. Germination will begin in about two to four weeks, depending on the quality and age of the seeds and the growing conditions.

4) Plant adaptations to different environments

The Carex oshimensis ‘Everillo’ has adapted to various environments through time. It can grow in different climates and soils.
