Hi Liz , yes Canadian daylililes can be exported and most will do well in N.C. but a Phyto Sanitary Certificate is required and the daylilies need to be inspected by the person's local agriculture department at both ends ( i.e. in your state for the ones you are wanting to ship and the canadian you are trading with whose plants will be coming to you )
Now on the Canadian end this can be done quite easily and inexpensively ( I have done it a couple of times to send plants into the USA) . What is required is that the plants are dug up and cleaned of all and I do mean all soil and the foliage is cut back and washed so that no insect or insect eggs are being harbored by the plant . The agent then inspects the plants and sometimes takes sample of the soil where they were grown to test . If all is good the certificate is issued and shipping the daylilies can go ahead . Additional costs are incurred for shipping of course and one must have all the proper documents attached to the shipment . It really isn't a difficult process but a necessary one . In my province the last phyto I got cost me $13.
The problem really stems from the other end . I.E. the USA . It used to be quite inexpensive to get a phyto certificate , however the costs of a phyto certificate in the USA varies from state to state and have gone up dramatically in the last few years. It used to cost nothing for a phyto in Alabama . I ordered many plants from a seller in Alabama at that time .
At the present time a phyto certificate can range from $25 in one state(Connecticut )to $50 in another state (Massachusetts) to over $100 in another (Georgia) . Many daylily sellers have stopped shipping to Canada I believe because of these costs (although it is the buyer who pays for these costs)however the shipper has to to do the work that is involved to get the certificate .
In actual fact during my experiences of ordering daylilies from the USA I discovered that there is supposed to be the same type of process involved in shipping from State to State in the USA. At least that was what I was told .
So if you were to want to trade you would have to go thru the process and the costs for obtaining a phyto certificate in your state to ship the plants out to your trade partner in Canada. Most people are not interested in doing this which is why I posted for trading only within Canada.
However , if you are willing I would be more than pleased to trade with you if I have something you want and vice versa
