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 5.5 to 7.8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 2.
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 April through May.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, fine in texture. Its flowers are conspicuous. It carries conspicuous autumn colour. Its active growth period is spring and summer. Its winter foliage is dense, which makes it useful for year-round screening. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 30 to 65 inches of annual precipitation. It needs at least 90 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
Propagate it from cuttings, bare root and container stock. 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. It spreads vegetatively at a slow rate.
Resilience and wildlife
Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated medium, and it can resprout after damage. Its growth form is recorded as thicket forming.
Role in a guild
Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. 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 JUHO2, 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.
