Salvia uliginosa

Phonetic Spelling
SAL-vee-ah ew-li-gi-NO-suh
Description

Sky-blue sage is an open, upright, spreading species of Salvia (sometimes listed as a half-hardy annual). Its ornamental appeal is the continuous display of small, clear sky blue flowers produced on the upright spikes. The flowers open in the morning and fall by late afternoon in hot weather but are replaced by newly opening flowers the next morning.

This salvia thrives in damp to boggy soil (common name is Bog Sage), tolerates poorly drained soils, but will also grow well in ordinary garden soil.  It is best planted at the back of the border as it could benefit from staking or mixing with other plants to hold it upright. It may become invasive in wet soils, spreading underground by rhizomes.
