That's a good plan. Dahlias are timeless.
I tried to tag you in a note, quite some time ago, about beargrass. I don't know if you saw that. I'd picked a bunch of it on a hike, put it in a vase. It lasted for weeks. I looked into ordering seeds right away. It might suffer the same volume/space issue as tulips, but it's unique, fragrant, and durable so it seemed worth mentioning.
