Adlumia fungosa flowering in September in a Mogadore, OH garden
An uncommon native Ohio species, the monotypic genus Adlumia can only be found at scattered sites in Northeastern and eastern part of the state. I am told that a population occurs in Summit county on an abandoned quarry, so while it may be a rare plant, it does appear to tolerate disturbance in natural ecosystems. The species occurs over a large geographical range in the northeastern and great lakes states, but is most abundant in the New England states.
In a family (Fumariaceae) that is well-known for species with exceptionally recalcitrant (unable to tolerate dry storage and/or short window of viability) seeds, this species has seeds that tolerate dry storage. A friend sent 3 packets of seeds. Each were harvested in a different year: 2007, 2008, and 2010. Each accession performed differently.
The pot at the top of the picture was sown with seeds dry stored since 2007, the middle pot sown with seeds dry stored since 2008, and the bottom bot sown with seed from 2010. As you can see, the seeds can be dry stored and retain viability for at least a few years.
