- Life cycle
Carex oshimensis 'Evergold', commonly known as Evergold sedge, begins its life as a seed which, when conditions are favorable, germinates in moist, well-draining soil. As a perennial, it enters a growth phase each spring, developing long, variegated leaves that form a dense, fountain-like clump. During the growing season, it may produce small, inconspicuous flowers, followed by seed-bearing spikes, although this plant is primarily grown for its foliage. Evergold sedge is a cool-season grass, so it actively grows during the spring and autumn while slowing down in the heat of summer. In the winter, growth ceases, and the plant goes dormant, but it is evergreen, retaining its leaves year-round in milder climates. As a perennial, it will re-emerge from its root system the following spring, repeating its life cycle.
The sedge known as Carex oshimensis 'Evergold', commonly referred to as Evergold sedge, is typically propagated through division. The ideal time to carry out this process is in the early spring or late fall when the plant is not in active growth. To propagate the Evergold sedge by division, carefully dig up the plant and gently pull apart the clumps into smaller sections, ensuring that each section has a portion of roots attached. These divisions can then be replanted in the ground or into pots at the same depth they were originally growing. It's important to water the new divisions thoroughly after planting to help establish them. This method of propagation allows the gardener to create new plants that are genetically identical to the parent plant, maintaining the variegated foliage pattern that 'Evergold' is known for.
