With its six to eight foot stature, Hewitt's Double meadow rue is a commanding perennial. It requires even moisture and full sun to stand tall without staking. Terminal sprays of airy pale purple flowers are produced in midsummer and are complemented by lovely columbine-like foliage. The leaves are often burnished with plum as they are growing.

- Culture Notes
- Like most meadow rues, 'Hewitt's Double' prefers light or open shade, but will tolerate full sun. Provide regular moisture during the growing season. This perennial takes a couple of years to reach its full stature and requires humus-rich soil. It should receive an annual topdressing of good compost or manure in late winter.
