But its flowers don't look like the flowers on any of those cacti. They look more like oxalis flowers. The buds appear, folded up, on thin stems that shoot straight up. As the flower unfolds, the stems bend and droop. The flowers last for weeks. Also, the spines on this plant are not sharp -- they are soft, more like hairs.
