1919, Quarantine No. 37

In 1919 a quarantine was issued for various plants and Irises were listed. It profoundly affected the importation of Iris both bulbous and rhizomatous and the robust offerings of especially bulbous and aril Irises were essentially eliminated from the catalogs of the day. There was much discussion in the American Iris Society lamenting these restrictions and in Garden Literature in General. It is believed that is had the practical effect of making bulbous Iris a minor interest in the American Iris Society because of their unavailability. Below is a list of references discussing the Quarantine:

I had many English, Spanish, and Dutch iris for mid-June show, but now I treasure but a few for they did not take to my light, poorly-nourished soil. They prove the best of all irises for cut-flowers and I only hope that the Horticultural Board will prove a true prophet in foreseeing a time when "Dutch" bulbs can be as well grown in this country as in Holland and gardens may show again the beauty of bulbs by the hundred. Personally my passing acquaintance with the bulbous irises has not been sufficient to give me a knowing appreciation of the varieties by name, but I hope that others will be able to give them individuality."
