Hi I have an extract botanic company at Venezuela. You do have a beautiful web page. I am about to build my own farm for my own raw material and one of the extract that we used more is calendula. I was seeing your marigold flowers and I want to be sure that these flowers are calendula. Thanks for reading this note. If they are the same could you give a hand picking the best of these marigold for extraction purpose and if you know where to get seeds. I went to school at Michigan, UofM but graduated at hillsdale college And my brother went to minessota. Beatufull and COLD place.
