After ten years of effort on the part of Taiwan, the butterfly orchid finally got the OK from the US for importation with its "growing medium" (soil) so that the plant can continue to grow, cutting costs by half. Currently, four private orchid farms have received US certification.
以蝴蝶蘭為例，經過 10 年努力，美國終於同意台灣蝴蝶蘭可以附帶「介質」（栽植土）輸入，使得植株生長期不會停頓，減少一半成本，目前已有 4 家民間蘭園通過美國認證。
