What is the world's oldest flower?

Answer 1

The oldest individual plants in the world are likely the bristlecone pine trees in California, which could be up to 5000 years old. Yew trees in Scotland, Andean pines, and European olive trees also have similarly long life spans.

Some tree species such as aspens branch off as clonesfrom a central plant, so colonies can be very large and very old. A Lomatia species known as Tasmanian Kings Holly has a lifespan of about 300 years, but a known clonal colony has been dated from fossil leaves to be at least 43,600 years old, and possibly as old as 135,000 years.

Answer 2

The world's oldest known flower may be a fossil belonging to the genus Archaefructus.
