Linguistics
Semantic Notes
In British English, the spelling 'lupin' is standard. The plant can be ornamental (Lupinus polyphyllus), a wildflower (Lupinus perennis), or an agricultural crop (Lupinus albus, Lupinus luteus). Edible seeds must be from 'sweet' cultivars to avoid toxic alkaloids.
Dialectal Variation
British vs American Usage
Differences
Primary difference is spelling: British 'lupin', American often 'lupine' for the plant. The American spelling is also the adjective meaning 'wolf-like'.
Connotations
In the UK, strongly associated with cottage gardens and coastal areas. In the US, wild lupines are native plants in certain regions (e.g., Texas bluebonnet). Both share agricultural/culinary contexts.
Frequency
Slightly more frequent in UK English due to popular ornamental cultivars (e.g., Russell lupins). In US, 'lupine' is common for the plant, but 'lupin' is used in scientific/agricultural contexts.

FAQ
Frequently Asked Questions
For the plant, 'lupin' (UK) and 'lupine' (US) refer to the same thing. However, 'lupine' (/ˈluː.paɪn/) is also an adjective meaning 'relating to or resembling a wolf'.
Yes, but only seeds from specially bred 'sweet' lupin species (e.g., Lupinus albus). Wild or 'bitter' lupins contain toxic alkaloids and must be extensively processed.
Uses include: ornamental gardening, as a cover crop/green manure to fix nitrogen in soil, forage for animals, and as a high-protein, gluten-free food ingredient (flour, beans).
It's relatively low-frequency overall but common in specific domains like gardening, sustainable agriculture, and specialty food. Gardeners in the UK are very familiar with it.
