Oligoneuron houghtonii

Also known as:

Houghton's goldenrod


Scientific Synonyms:

Solidago houghtonii


Oligoneuron houghtonii is an extremely rare species of goldenrod. It has broad, oval basal foliage, and sparse elongated leaves growing along its stiff, unbranched central stem. Typically growing to a height of 3', it is topped by a cluster of large yellow flowers. Easily confused with the more common Solidago ohioensis and Euthamia graminifolia, it has considerably larger flowers and fewer leaves than either, and is unbranched unlike the latter.


Endemic to only a handful of counties in Michigan, and a single disjunct population New York, its habitat includes sandy interdunal wetlands and depressions, and wet ditches. Its preference is wet, sandy, alkaline soil in full sun, but can adapt to more common conditions so long as the soil remains consistently moist to wet. Plants may die back if submerged for an extended period, but will bounce back once the area has drained. The root system is rhizomatous and individual plants will slowly spread vegetatively to form small clumps. Id does not spread aggressively from seed. The blooming period occurs late summer to mid-fall and can extend for about 2 months. Zones 4-7


Propagate by clump divisions or root cuttings. Can also be propagated from seed, although the exact protocols are still being researched.

Additional Notes

This federally endangered species is showing early signs of commercial potential for use in rain gardens and water management systems.
