Bruised leaves of the herb have an aroma similar to that of an apple and they are dehydrated and burnt to keep away flies.

While the native tribes of North America have been using gravel root for therapeutic purposes for centuries, when the European settlers arrived in the continent, they were fast to espouse the herb and the plant continues to be used in contemporary herbal medicine. The entire gravel root herb, particularly its root, possesses diuretic, astringent, tonic and nervine properties. It is especially useful in treating the problems of the genitals, the urinary tract and the uterus. Gravel root is particularly useful for its actions as an energizer and diuretic. In addition it is also valuable for its astringent attributes. An herbal tea prepared with gravel root rhizome and leaves is employed to get rid of stones from the urinary system, to cure urinary incontinence (inability to restrain urine discharge) in children and impotence. The leaves as well as the flower-bearing stems of the gravel root are harvested in summer prior to the opening of the buds and dried for use when necessary. The roots of gravel root, which are considered to be the most potent part of the herb, are dug up in autumn and dried for future use.

Habitat and cultivation

The herbaceous perennial plant gravel root is native to North America and is found growing naturally in damp woodland and meadows extending from southern Canada to Florida and westwards to Texas.

Gravel root plants thrive well in common garden soil which has adequate drainage, but can retain moisture in sun or partial shade. Plants belonging to this species may be cultivated in somewhat rough grass that can be mowed or cut every year during autumn. Gravel root has the ability to tolerate extreme cold conditions and can endure as low temperature as approximately -25°C. The crushed leaves of gravel root have an aroma that is akin to that of vanilla/apple. These plants appear to be unaffected by the intrusion and preying by rabbits. Interestingly enough, butterflies are drawn by gravel root. This species may be propagated by its seeds or root division.

The seeds of gravel root should be sown in spring in a cold frame and it is advisable that you only cover the seeds. When the seedlings have grown sufficiently large to be handled, prick them individually and plant them in separate pots. The young plants may be transplanted into their permanent positions outdoors during the summer. Propagation by division of roots should ideally be done in spring or autumn. It is quite simple to grow the plant by root separation and it is possible to re-plant the thickets into their enduring positions outdoors.

When gravel root is grown in the gardens, this plant blends excellently with showy grasses to offer a typical ‘prairie' appearance, but also appears similarly effectual when grown with lofty sub-tropical flowers, for instance Dahlia, Salvia, Canna and Brillantaisia in a range of colors, including white, pink, blue and cerise.

The plants require cutting to the ground during winter. The height of the plants notwithstanding, they hardly require staking (poles to support the plants). In effect, there are various cultivars of gravel root, counting ‘Purple Bush' and “Gateway'.
