Moluccella laevis. Annual produces scented lime-green flowers (calyxes actually) on tall (1m) spikes. Makes a lovely background plant and is also used as a long-lasting cut flower that won't steal the show. Nice in containers in a cool area. Plants may need support in fertile soil. Flowers in late summer. Best to direct-sow in early spring— seeds need light and a period of cold moist stratification to germinate. Will probably self-seed in the garden.
