Taiwan moth orchid cultivars already represent great achievements, Chen notes. There are large-, medium- and small-bloom varieties. Their flowers show a great variety of shape and color, from pure white, to blooms tinged with pink, to those that are speckled or striped. But the "delicate fragrance in the valley" that used to characterize wild orchids has been lost over generations of hybridization.
陳文輝指出，台灣蝴蝶蘭育種已「登峰造極」，從大花、中花到小型花，從純色、帶紅暈、噴點到線條，各花型、花色琳瑯滿目，但早年「空谷幽蘭」的那縷幽香，卻在代代雜交中佚失，這幾年各方育種者於是開始在香氣上動腦筋。
