Where was this filmed?

Probably in Skagit County, Washington. They have tons of tulip fields like this during the tulip festivals in springtime.

It was actually filmed in Canada. Believe it or not, most of the tulips were fake, per Fiona. The actors tweeted this information during filming, that's how I found out. I believe it was Vancouver, for the most part. Hallmark films many of their Movies and series up there.

I thought it was filmed in Woodburn, Oregon. They have a huge tulip farm there.
