Silver Scilla
This old soul was first described in 1870 as a native of South Africa. Another common name,“Leopard Lily”, refers to the dark green to turquoise markings over frosted-silver, strap-like leaves that are too huge for mini landscaping plus the (lily) bulb below. Though it resists drought in its native savannas, it's perfectly tolerant of terrariums and dish gardens. It sends up white flower spikes whenever it wants.
