Rainy Side Notes

For sky blue flowers and tall growth, this perennial gives you both in the late summer and autumn garden. Its epithet uliginosa means of swamp and marshes, and is a testament to where it grows in its native habitat.

This sage can grow aggressively in wet areas; to keep it in check, grow it in well-drained soil with infrequent watering. By doing so, it will stay within a four-foot area and not roam aimlessly around the garden.

Salvia uliginosa makes a good cut flower.
