Where do lupine flowers grow?

There are many species of flowers known as lupine, but the most commonly known are those western wildflowers of North America known as Texas bluebonnet. Wild species are also native to South America and the Mediterranean region of Europe and North Africa. Lupine have the unique ability to use nitrogen from the atmosphere rather than from the soil like ordinary plants. This allows them to colonize soils that are too poor for other plants, which explains why they are so common in the thin roadside gravels of the West.

Some of the Lupine species used in gardens are linked below, but there are many other hybrids which offer bigger plants with extraordinary range of flower size and color.
