perennial veldtgrass
Ehrharta calycina · Poaceae
perennial veldtgrass (Ehrharta calycina) is a perennial grass or grass-like plant in the Poaceae family. It is introduced to North America rather than native. USDA records it as hardy in zone 8 and warmer, down to about 17°F.

Growing conditions
It needs full sun. USDA rates it as having moderate water needs. 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 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 8.
Size and growth
At maturity it reaches about 4 ft, making it roughly waist to chest height. It grows quickly.
Bloom period
USDA records a bloom period of March through May. Flowers are yellow.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, fine in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is fall, winter and spring. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.
What the site needs to provide
USDA records it across sites receiving 24 to 80 inches of annual precipitation. It needs at least 120 frost-free days to finish its season. It roots to at least 16 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 moderate rate. It spreads vegetatively at a moderate rate.
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 colonizing.
Role in a guild
Herb layer. In a layered planting this is the herbaceous middle — perennials and grasses that fill the space between ground cover and shrubs. 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 EHCA, 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.
