rough fescue (Festuca campestris) is a perennial grass or grass-like plant in the Poaceae family. It is native to North America. USDA records it as hardy in zone 3 and warmer, down to about -38°F.

⚠ Allelopathic. USDA flags this plant as releasing compounds that can suppress the growth of plants near it. Give neighbours extra room, and expect some companions to struggle regardless of how well their conditions match.

Both flags are quoted from USDA PLANTS, not inferred.

Growing conditions

It grows in partial shade. USDA rates it as having low water needs once established. Its drought tolerance is rated low. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 6 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 3.

Size and growth

At maturity it reaches about 1.5 ft, making it about knee height. It grows slowly.

Bloom period

USDA records a bloom period of July. Flowers are yellow.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is spring and summer. USDA rates its lifespan as moderate.

What the site needs to provide

USDA records it across sites receiving 16 to 24 inches of annual precipitation. It needs at least 90 frost-free days to finish its season. It roots to at least 14 inches. Fertility requirement: medium.

Propagating it

Seed is the only propagation method USDA lists. Division and cuttings are not listed as options. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a slow rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated medium. Its growth form is recorded as bunch.

Role in a guild

Ground cover. In a layered planting this is the lowest layer — it shades soil, holds moisture, and suppresses weeds. The layer is derived by a fixed rule from growth habit and mature height.

Where this data comes from

Every value on this page comes from the USDA PLANTS database record for symbol FECA4, or is computed from those values by a fixed rule. Nothing here is estimated or model-generated. Where USDA publishes no value, this page omits the claim rather than filling the gap.
