But before you start planning where to plant this California native in your garden, there’s something important you need to know about this remarkable little wildflower.

What Makes Anthony Peak Lupine Special

This herbaceous beauty is a true California native, belonging exclusively to the Golden State. However, what makes this lupine truly extraordinary isn’t just where it grows – it’s how incredibly rare it is.

Let that sink in for a moment. This lupine is hanging on by a thread in the wild, making it one of California’s botanical treasures that desperately needs our protection.
