Pacific Island silvergrass

Miscanthus floridulus

Pacific Island silvergrass is a clumping, evergreen grass that grows in tropical climates. It is endemic to select Pacific islands and grows to about 4 to 5 feet tall. The species has large, silver-green leaves that form fluffy flowerheads with silky threads of golden-brown seeds. The flowering and seeding season is short, usually beginning in late summer and peaking in late fall. Pacific Island silvergrass has several uses, such as erosion control along roadsides, wildlife habitats, and as an ornamental grass in landscaping projects. It’s a great choice for low-water, low-maintenance gardens.

watering

Pacific Island silvergrass should be watered regularly, though not too frequently. Water the plant every 2-3 days during the growing season, and every 4-6 days during the dormant season. Be sure to water deeply, enabling the water to reach the root system located 2 inches below the surface of the soil. Be sure not to water too much, as this can lead to root rot. If the soil remains wet for too long, refrain from watering until the top layer of soil is dry; this will prevent the plant from developing a shallow root system. Finally, remove any excess water from the pot after each watering, as the plant does not thrive in wet soil.

sunlight

Pacific Island silver grass is a tropical and subtropical plant species which grows best in warm and sunny climates. Ideally, Pacific Island silver grass should receive at least 6 to 8 hours of direct sunlight during the day, but can also tolerate dappled shade. During the hottest parts of the year, it might be best to provide the plant with some afternoon shade to prevent any scorching or wilting. During winter months, Pacific Island silver grass may require more sun exposure and additional lights can be provided as needed.

pruning

Pacific Island silvergrass should be pruned in the spring and fall, just before the new growth begins. Pruning in the spring should reduce the overall height and spread of the plant, while removing dead or diseased foliage. In the fall, pruning can be done to shape the plant, remove any dead foliage, or to open up the canopy to allow for better light and air circulation. Pruning should be done carefully as this species tends to have shallow roots that can easily be damaged.
