Do NOT eat this plant!!!
Oleander
Flowers are white, red or pink. Highly prolific, and used in landscaping. Leaves are also used for suicide in some parts of the world. This plant is DEADLY!!
If it gets to the point where this is necessary to survive (and will last longer than a bottle of thousand island) then please point me to the oleander.
Even in the horrid german concentration camps people clung to life - it's who we are... Best to prepare - you'll keep wanting "one more day" - just like the rest of us.
