An outstanding selection, award-winning Veronica austriaca subsp. teucrium ‘Crater Lake Blue’ (Saw-Leaved Speedwell) is a compact, mound-forming perennial boasting intense gentian blue flowers arising in elongated axillary racemes from late spring to early summer. When in flower, this plant is a sea of blue. Crater Lake Blue is regarded as one of the best cultivars for filling in a sunny area in the front of the garden. The foliage of toothed, oblong, bright-green leaves looks good all season. A very versatile plant for rock gardens or border fronts.
