White Lupine Lupinus albus

Deer-resistant — Low palatability to browsing deer, and rated toxic — which deer tend to avoid. Usually passed over, but no plant is truly deer-proof when food is scarce.
USDA livestock toxicity rating — not a pet assessment. See the Toxicity detail further down for what's documented.
Also known as: White Lupin

White Lupine is an introduced annual herb, found in the lower 48 states. It grows to 4 ft and blooms Aug in part shade – shade, with black fruit.

❧ Caterpillar hosts ~33 caterpillar species

Lupinus supports ~33 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 strong genus.

Recorded feeding on Lupinus in North America, including:

Anacampsis lupinella · twirler moth Arachnis picta · Painted Tiger Moth Arctia caja · Garden Tiger Areniscythris brachypteris Argyrotaenia citrana · leafroller moth Argyrotaenia franciscana · Orange Tortrix

✦ Bees specialist-bee host · 28 bee visitors

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Lupinus is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.

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

We read each species’ measured specific leaf area (leaf area per unit dry weight) from the Global Spectrum dataset and band it: thin & fast (high SLA), medium, or thick & tough (low SLA). The global median is about 10 mm²/mg.

Honest limits: A species-mean from pooled measurements — individual plants vary with light and site. A broad strategy signal, not a precise per-plant figure.

Díaz, S. et al. (2022) The global spectrum of plant form and function: enhanced species-level trait dataset. Scientific Data 9:755.
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.
