American Spikenard Aralia racemosa

Native

American Spikenard is a perennial shrub native to Canada and the lower 48 states. It grows to 7 ft and blooms Jul – Aug.

More about this plant

Aralia racemosa, with common names American spikenard, small spikenard, Indian root, spice berry, spignet, life-of-man, petty morel, is an ornamental plant in the family Araliaceae native to the United States and Canada. It is a herbaceous plant, about 1 to 2 m tall, which grows in shady areas. Its native range includes most of the eastern United States. Wikipedia →

❧ Caterpillar hosts ~8 caterpillar species

Aralia supports ~8 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.

Recorded feeding on Aralia in North America, including:

Aphelia alleniana · Wide-Striped Leafroller Argyrotaenia repertana · leafroller moth Celastrina argiolus · Holly Blue Dichomeris juncidella · twirler moth Eupithecia satyrata · Satyr Pug Lymantria dispar · Gypsy Moth

How we know this (2) Methods & honest limits
Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.

Kattge, J. et al. TRY plant trait database — Categorical Traits Dataset (2012).
Climate niche (heat tolerance & native rainfall) Derived

We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.

Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.

Realized-niche / climate-envelope approach (Pearson & Dawson 2003; Soberón 2007). Climate: NOAA NCEI nClimDiv county normals (1991–2020).
Derived values are computed from open data by a published method — labelled, cited, and never shown as a direct observation. Full methodology →
