Octopus Bush

• Forms a ring around the outside of the of the island
• Seeds need to be immersed in the ocean before they can germinate
• Use salt water for their water requirements, deposits the excess salt onto one leaf on each bunch, turning it yellow.
• To minimise water loss it has developed hair covered leaves, these hairs also give the plant a silver hue, reflecting large amounts of the sun's heat rather than absorbing it.
