Growing conditions

It needs full sun. USDA rates it as having low water needs once established. Its drought tolerance is rated medium. It tolerates saturated, poorly drained ground well (USDA rates its anaerobic tolerance high). It is recorded on soils from pH 5 to 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 3.

Size and growth

At maturity it reaches about 12 ft, making it a small tree or large shrub. It grows at a moderate rate.

Bloom period

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

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, medium 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 8 to 18 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 88 frost-free days to finish its season. It roots to at least 36 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

It takes readily from seed, cuttings, container stock and sprigs. 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 rapid rate. It spreads vegetatively at a slow rate.

Resilience and wildlife

Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. 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 SAMO2, 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.
