Outstanding Qualities

This vigorous and tough perennial is named for the vibrant smokey violet-blue and purple flowers that stand lupine-like above the plant on strong charcoal colored stems. The flowers and stems contrast beautifully with the bright grey green leaves that form a dense bushy mass below. It is easy to grow and will thrive with little maintenance and is very long-lived and drought tolerant once established

Culture Notes
This smoky blue indigo grows best in full sun with well-drained soil and is tolerant of sandy and clay situations. Rich organic soils and heavy fertilizing can make it floppy and growing it in lean and poor soils will produce a more compact plant. Once established it is drought tolerant. This is a very easy perennial with almost no health issues, but it is slow growing and resents being disturbed so provide with plenty of room in the garden.
