This plant livers in part sun on my patio in a pot. It dies back when it freezes for about 2 months in the winter. It comes from a surface planted bulb and multiplies by making new bulbs. Flower is not interesting, I think white. It makes single shiny leaves on separate stems. Approximately a 12" tall clump of lush leaves. Up to 105 degrees in summer. Watered when dry. Photographed plant is a young one these bulbs are 1/2", adult bulbs are1.5" approx. what is this plant!?
