Top 10 Incredibly Rare Flowers - Listverse
Koki'o - This is an extremely rare tree, endemic to Hawaii. It was discovered in 1860, at which time only three specimens could be found. The tree proved difficult to propagate, and by 1950, after the last seedling died, it was deemed extinct. In 1970 a sole survivor was found, which was sadly destroyed in a fire in 1978. Luckily one of the branches of that last remaining tree was saved, and grafted into 23 trees that exist today, Known for the hundreds of bright red flowers produced annually.
