Silver Bush Lupine (Lupinus albifrons). Lupine is the butterfly hostess with the mostest. With beautiful purple blooms, it's native to the West Coast from Oregon down to Baja, Mexico, preferring dry areas. There are a whole host of native California butterflies that will reproduce only in Lupine! One of the loveliest is Mission Blue Butterfly, with delicate blue wings fringed with white and purple.
Purple Sage (Salvia 'Celestial Blue'). This hybrid loves extreme heat and is great for the sunny areas of your garden. In addition to butterflies, swallowtails adore the nectar of its amazing blue blooms.
