Growing conditions
It tolerates full shade. USDA rates it as having low water needs once established. Its drought tolerance is rated none — it needs reliable moisture. It is recorded on soils from pH 5.5 to 6 — acidic ground. Its cold limit is zone 4.
Size and growth
At maturity it reaches about 1.5 ft, making it about knee height. It grows quickly.
Bloom period
USDA records a bloom period of June. Flowers are purple.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, fine in texture. Its flowers are conspicuous. Its active growth period is spring and summer. 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 55 to 155 inches of annual precipitation. It needs at least 200 frost-free days to finish its season. It roots to at least 6 inches. Fertility requirement: medium.
Propagating it
It takes readily from seed, cuttings, bare root, container stock, corms and tubers. Seed needs cold stratification — a period of moist chilling — before it will germinate, so sow in autumn or chill it artificially before a spring sowing. 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 high. Its growth form is recorded as rhizomatous.
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 DIFO, 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.
