How to Choose
When selecting ornamental grasses for full sun, consider size and growth habit to fit your garden’s scale and design goals. Evaluate drought tolerance if you live in a dry climate, and soil preferences to ensure healthy growth. Flowering time and color add seasonal interest, so pick varieties that extend visual appeal through different seasons. Also, check for invasive tendencies, especially with species like Nassella tenuissima. Finally, think about maintenance: clumping grasses generally require less division than running types, and some need annual cutting back to promote fresh growth.
Frequently Asked Questions
Are ornamental grasses invasive? Some species, such as Pampas grass and Mexican feather grass, can be invasive in certain regions. Always check local regulations before planting and choose clumping varieties to avoid spreading.
How often do ornamental grasses need watering? Most established grasses are drought-tolerant but benefit from occasional deep watering during prolonged dry spells, especially in their first season.
