Plant Common Name

Mountain Madwort

General Description

Mountain madwort is native to the Mediterranean. It is a mound forming perennial that produces fragrant clusters of yellow flowers borne above gray-green hairy foliage.

Mountain Madwort thrives best in dry rocky soil and has a preference to full sun, although it will tolerate light shade. Add vibrancy to the facade of stone walls by planting mountain madwortin empty crevices or plant towards the front of dry borders. Interesting addition to the edge of a large alpine trough container. Cultivars such as 'Mountain Gold' ('Berggold') and 'River of Gold' make nice spring additions to rock gardens.
