Neofinetia falcata Hisui is probably the best of the green-flowering Neos. The flowers are at least as big as the standard furan, and the green color is quite obvious (though hard to photograph well). Despite rumors to the contrary, colored Neo flowers are as wonderfully fragrant as their white counterparts.
These are MULTI-GROWTH plants, blooming size, and potted in traditional style. These guys are a great deal!
