East Dean and Friston
This is the evening primrose,
Blooms open in the evening) so beloved by ladies with menstrual
tension issues. The whole plant is edible - roots are said to taste like
potato. The oil that is used medicinally comes from the seeds which are 24%
wv oil. although tasty and medically beneficial, in sensitive individuals it
can increase the likelihood of epileptic episodes.
I found it just along the A259 outside the village.
