Beardtongue gets a bit heavy, and can benefit by being planted next to another shrub.

The ones I've grown have survived 20 F with no mulching or any other protection.

Looks good with annuals.

quite a vigorous grower for me, it is an evergreen perennial. needs moderate summer water. the flowers are bluish-purple spring-fall, nice planted at eye level in elevated flower bed, as branching is heavy and tend to bend.
