Cabbage on a stick

Plant Botanical Name: 
Brighamia insignis
USBG Plant Location: 
Conservatory Room Location: 
Plant Threat Level: 

Cabbage on a stick is "Critically Endangered" and is now found naturally growing on only one sea cliff on the Hawaiian island of Kauai. Overgrazing, human development and competition from invasive plants have reduced this species to just a few naturally occurring individuals. The extinction of its pollinator, the sphingid moth, has made it all but impossible for Brighamia insignis to reproduce on its own. Conservationists go to great lengths to pollinate these remaing plants and to collect seeds that are grown in botanical gardens or stored in seed banks.
