Rainy Side Notes
For blue flowers and tall growth, this perennial gives to both the late summer and autumn garden. In its native habitat, it grows in bogs. Its epithet, uliginosa, means of swamp and marshes. It is a spreading plant and can grow aggressively in wet areas; it is easier to keep in check if you grow it in well-drained soil with infrequent watering; by doing so, it will stay within a four-foot area and not wander aimlessly around the garden, unlike myself, since I constantly roam aimlessly around.
Salvia uliginosa is a good cut flower.
