Salvia argentea is a biennial or short-lived perennial cultivated primarily for its massive, downy-silver rosettes of foliage that command attention all season. In its second year, it sends up 3-foot spires of white or pinkish flowers with gray calyces in mid-to-late summer. The spiky form (3 feet tall, 2 feet wide) makes a dramatic architectural statement.
Sow seed or divide in spring. Watch for powdery mildew, rust, stem rot, fungal leaf spots, whiteflies, aphids, mealybugs, spider mites—especially in humid conditions with poor drainage.
