What is the most unusual plant in North America?

    I’m going to give my vote to the smooth carrion flower, Smilax herbacea. Not visually so unusual, especially compared to its enormous African relatives, this flower is a vine that can grow from 6-8 feet tall and contains small yellowish green flowers and clinging tendrils (not uncommon to other species). The reason I given it my vote for most unusual is the absolutely rank smell it emits, often compared to that of a dead rat or rotting carcass; hence ‘carrion’ in its name. You might notice the flies hovering nearby after smelling it. It’s native to the eastern parts of North America, and is a great prank for Valentine’s Day, if you needed any ideas.

    This is my personal opinion – and maybe they aren’t so unusual anymore – but I think that all of the trees that are being developed to harvest for biofuel are pretty interesting!  Here’s one website that tells about a bunch of different kinds –

    My vote is the avocado tree. It is such a strange fruit, the creamy fatty flesh isn’t like anything else I’ve ever eaten. Somewhere in a textbook once I read a theory that they evolved as food for ice age megafauna like giant sloths.

    I think that a lot of species of cacti are very strange looking. Take the Saguaro Cactus (Cereus giganteus) for instance – here’s this very prickly, very sharp looking thing, yet it blooms these lovely, waxy- looking flowers:


    Plus it’s growth patterns are quite strange – it absorbs water, and as it does it swells largely at the base. In this matter its weight can increase by as much as a ton. It’s life span is quite surprising as well – it can live as long as 200 years.

    A feild of Saguaros:
