All around South Florida there are large trees blooming with no leaves and large showy pink blossoms. As you get closer to these trees, you will notice large thorns on the trunks and large surface roots. The trees that you are viewing are Silk Cotton or Silk Floss Trees (Chorisia speciosa). A member of the Bombacaceae Family, Chorisia speciosa is a spectacular tree in its own right, and the blossoms are just icing on the cake. To be up to date, the botanical name has changed to Ceiba speciosa, at least for now.
Richard Lyons Nursery has these trees available at the current time.
