Ipheion uniflorum 'Alberto Castillo' is a small, South American bulbous plant in the onion family. Flowers are typically some shade of blue but 'Alberto Castillo' is a robust, large-flowered plant with pure white flowers that was originally collected in Buenos Aires, Argentina. A few bulbs were given to me by Rob Hopper. I grew the bulbs as potted plants but Rob also planted them in the ground, where they grew equally well and freely flowered.
