Blue Chalksticks
A very fun South African native that makes a wonderful groundcover in climates where it’s warm enough to survive year round. For those of us north of Zone 9 it makes a lovely container plant that can be moved indoors during hard frosts, and some adventurous gardeners in Zone 8b are trying it outdoors, but it’s typically melted at temperatures lower than 25.
