Again this year the list is long and interesting: Danish Seed Savers exchange list
See eg. the exciting Caucasian Spinach (Hablitzia tamnoides), originating from the Caucasus, and with history of cultivation in Scandinavia, mostly in manor gardens.
In my garden I have a few frozen pots with seedlings of Caucasian Spinach, from the seeds I got last year from a seed savers. When spring comes, I’ll transplant them near a tree or shrub in the shade, where it may otherwise be difficult to grow vegetables.
On facebook, there is now a Group, Friends of Hablitzia tamnoides, the Caucasian Spinach
Prinsesse bean is a classic on the exchange list. It’s live Danish heritage, preserved by a vegetarian family for generations. 100 years ago it was a well-known cultivar, mentioned in gardening books as the earliest bean to grow. Now used mostly as dry bean, and then it’s a lovely name!
It is also spelled with c: Princesse
Do I need to translate the name: Princess it is in queens English :-)
