East Friesland meadow sage produces tall, violet-purple flower spikes above compact mounds of aromatic gray-green foliage, blooming profusely from early summer through fall, especially with regular deadheading. Its dense, well-behaved habit and long bloom period make it a workhorse of the perennial border, where it pairs beautifully with yellow-flowered companions like coreopsis or rudbeckia. It draws bees, butterflies, and hummingbirds throughout its bloom season.
