The population has decreased in size from 5,000 individuals in 1995 to 1,000 in 2010. Nearly all of the original type location had either been bulldozed to build a new police station or planted with conifers under which the species could not grow. The remnant population exists now on the hillside and road banks, the hillside has been planted with conifers and the road may be expanded as it is the main south coast holiday route.
It has a yellow standard with red veins. It is strongly scented, but its fragrance is different from the sweet pea.
Embryo rescue techniques have been used to hybridize it with the sweet pea. This has resulted in new Lathyrus odoratus cultivars like the Sweet Pea "Erewhon", and there is hope that it can be used to introduce the yellow color into Lathyrus odoratus.
