Ceiba speciosa and Ceiba chodatii, commonly referred to as the Silk Floss Trees, are flowering trees of the Malvacea family. Theyare native to the subtropical forests of South America. Both the pink- and creamy-yellow-flowering trees are also known as the 'drunken tree'.
Here the red and cream trees can be seen blooming together
The common English name of Silk Floss Tree is more readily understood as the seeds are surrounded by a white, fluffy silk-like material. Both trees are drought tolerant and will grow quickly when water is abundant. They can also tolerate moderately cold temperatures and are frequently planted in parks and along roadsides.
The trunks and branches of these attractive trees have very large, sharp thorns.
