Energize Your Landscape with Mass Plantings of Ornamental Grasses

Grasses bring movement, light, shadow, and seasonal evolution to the garden. Planted in masses, they become the landscape's dominant voice—harmonizing architecture with the regional environment through simple, bold palettes.

Plant in Drifts

Feather reed grass (Calamagrostis 'Karl Foerster') connects and frames views, screens eyesores, and stands tall through winter until spring cutback. Its vertical structure animates the dormant season.

Frame Views from the House

Choose grasses that transform in winter—reed grass, bluestem, woodoats, Spodiopogon. Maiden grass (Miscanthus sinensis 'Gracillimus') catches snow on its seed heads, creating winter magic.

Plant in Context

A handful of grasses among shrubs looks accidental. Be bold: plant grand masses of Pennisetum and Calamagrostis on their own. They seat the home in the landscape with modern, sublime simplicity—no gaudy specimens needed.

Low-Maintenance Partners

Underplant airy shrubs like Russian sage (Perovskia) with autumn moor grass (Sesleria autumnalis), prairie dropseed (Sporobolus heterolepis), or Pennsylvania sedge (Carex pensylvanica) to suppress weeds. These long-lived grasses outcompete invaders; bulbs can be tucked in without disturbing roots.

Leave Them Standing for Winter

Don't cut back in fall. Observe which grasses hold form beautifully—'Karl Foerster' rebounds upright after freezing. Cool-season grasses emerge early, providing structure when little else is awake.

Evergreen Options for Year-Round Green

Autumn moor grass stays green through most Philadelphia winters, thriving in light shade alongside Calamagrostis brachytricha and Carex species.

Seasonal Color Shifts

Japanese forest grass (Hakonechloa macra) excels in dry shade—lush green in summer, blonde in winter. 'All Gold' chartreuse brightens dark corners under maples.

Texture Over Color

Mexican feather grass (Stipa tenuissima) offers fine, billowy foliage versatile enough for East Coast gardens. Pair in blocks around flowering perennials like giant hyssop (Agastache 'Blue Fortune').

Let Grasses Dominate the Ground Plane

Masses of Carex punctuated by agave create an artful, simplified planting. Architectural features—millstone fountain, fire bowl, seat wall—anchor the space for gatherings.
