There flowers are called Acidanthera or peacock orchids, or peacock iris so I just call them peacock flowers because they are as beautiful as a white peacock in full feather. They do come from bulbs that bloom in mid summer. I grew mine on my sunroom and they have done great. They are an inexpensive bulb that can be found on sale in the early spring. They do have long, strappy type leaves that are almost like a thick leafed grass and needed to be staked so they wouldn't fall over. The center of the flower has a arrow shaped deep shade of purple or burgundy red shape on each petal. The flowers don't seem to last very long and I don't think they would make good cut flowers but have made a bright splash of color in my indoor garden. I took some photos of the flowers at night with a flash against a dark window and I am very pleased with the outcome. Need to try some other flowers this way.
