Growing conditions

It grows in partial shade. 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 4.8 to 8.4 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 1.

Size and growth

At maturity it reaches about 15 ft, making it a small tree or large shrub. It grows at a moderate rate.

Bloom period

USDA records a bloom period of June. Flowers are white.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, coarse in texture. Its flowers are conspicuous. Its fruit or seed heads are conspicuous, extending interest past flowering. 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 12 to 140 inches of annual precipitation. The low end of that band is genuinely arid, so it has a wide tolerance for dry country. It needs at least 100 frost-free days to finish its season. It roots to at least 24 inches. Fertility requirement: medium.

Propagating it

It takes readily from seed, 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. Its seed spreads at a slow rate. It spreads vegetatively at a moderate rate.

Resilience and wildlife

Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated high, and it can resprout after damage. Its growth form is recorded as multiple stem.

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 AMAL2, 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.

USDA also lists this plant under symbol AMALS, recorded at a finer rank (variety or subspecies) under the same accepted name and common name. We show one entry rather than near-identical repeats; the figures above are those of AMAL2 alone, not an average across them.
