Good to hear that you had such nice experiences dealing with Eurohosta
Dragracing sounds dangerous, but exiting!!! Yes, Mantorp Parc is correct but it's spelled Mantorp Park.
Daylilies are very hardy so many can be grown in almost all of Sweden, but probably one should be careful with evergreens in the north. Also some daylily cultivars don't develop their edge colour in a normal fashion, because of the lack of heat in our summers. That said I'm not a huge daylily grower, although I really love the ones I have. I have very sandy soil (8 meters of pure sand and the ground water is at this depth also) so I must limit the number of thirsty plants a bit as it can be very dry here in summer.
Winters here in the south are often very long, but actually not necessarily very cold, although they can be. Certainly they are a lot colder than your winters. Usually there is a freeze-thaw cycle and this is what kills the majority of plants. Summer are usually quite cold at least compared to continental Europe or large parts of the USA, but here in this micro climate in the forest where I live we usually have a reasonably long frost free season.
Many thanks for the kind offer to help with the bulbs
, but it works exemplary to order directly from for instance Eurobulb or Fluwel and I have done so many times the last few years. I do love the selection and the low prices compared to Swedish shops!
Didn't know about happygarden, so bookmarked that one. Looks interesting!
If I were you I'd definitely check out Cayeux next year
Oh and don't give up, the best of the American cultivars are sure to be available here in Europe, although it could take some time.
Now back to trying to narrow down that wish list from Cayeux. Not sure how large part of the kitchen garden that is okay to transform to an iris nursery bed
