Too funny! I bought them after reading that blog! Thanks, gal.

Great minds . . . . . . . . . . . . . . . . !

Yes! Do you know if these should be planted rather shallowly or not? Thank you!

Gerald is a cross between versicolor and virginica. The below advice ought to apply. I would plant with the root mass/rhizomes just under the dirt. Since they're bog loving there's no worry about rotting a crown.

7. Replant the healthy sections after dividing in rich, organic soil just under the soil surface, with one end of the rhizome sticking out slightly. Ideally, do this in a partly sunny to partly shady location, spacing rhizomes two to three feet apart.

Thanks IG! Do you know if these are super vigorous or not?

Wow - that really is cool! I love dark stems.
