I have not taken time to address this.
Delphinium perennials are NOT in this category. Unless there are rare cultivars which might ?
Larkspur annuals are Not either. But Larkspur seeds are not viable as they are harvested. The seeds can be stored dry, but the seeds contain incomplete embryos which grow only if subjected to cooler moist conditions.
Jeffersonia is usually sent in moist packing.
I have received peony seeds in moist packing, but I do NOT think this is necessary.
Some seeds go the other direction. Poppy seeds germinate better after some dry storage.
