Solidago rigida, known by the common names stiff goldenrod and stiff-leaved goldenrod, is a North American plant species in the family Asteraceae. It has a widespread distribution in Canada and the United States, where it is found primarily east of the Rocky Mountains.[2] It is typically found in open, dry areas associated with calcareous or sandy soil. Habitats include prairies, savannas, and glades.[3]

Description
editSoliadgo rigida is a tall, leafy perennial. Its leathery leaves are large for a goldenrod, reaching 3–6 cm (1+1⁄4–2+1⁄4 in) wide and 8–20 cm (3+1⁄4–7+3⁄4 in) long. It produces heads of yellow flowers in the late summer and fall.[3] Its fruit is a wind-dispersed achene.
Galls
editThis species is host to the following insect induced galls:
- Asphondylia s-rigida-bud-rosette-gall
- Asteromyia carbonifera (Osten Sacken, 1862)
- Gnorimoschema gibsoniella Busck, 1915
- Calycomyza solidaginis Kaltenbach, 1869[4]
Subspecies
edit- Solidago rigida subsp. glabrata (E.L.Braun) S.B.Heard & Semple – southeastern + south-central U.S.
- Solidago rigida subsp. humilis (Porter) S.B.Heard & Semple – central + western Canada, central + western United States as far west as the Rocky Mountains
- Solidago rigida subsp. rigida – Ontario, central + eastern U.S.
-
Subspecies glabrata has hairless outer phyllaries, and a less pubescent stem and leaves
Conservation
editThis species is considered by NatureServe to be globally "secure" (G5), which is the lowest level of conservation concern assigned.[5] However, it is known to be rare on the local level, due to its declining grassland habitat. It is listed as endangered in Connecticut,[6] New Jersey and Pennsylvania. It is listed as endangered and extirpated in Maryland, as threatened in New York, and as historical in Rhode Island.[7]
Native American ethnobotany
editThe Ojibwe use a decoction of root as an enema,[8] and take an infusion of the root to treat "stoppage of urine".[9] The Meskwaki make the flowers into a lotion and use them on bee stings and for swollen faces.[10]
