A plant pundit comments on plants, the foibles and fun of academic life, and other things of interest.
Do not hug this Teddy Bear
Lots of plants in the desert have some spiny protections, but as far as TPP is concerned some of the bushy prickly pears are the worse. The image is Opuntia biglovii, a much branched, very prickly species that goes by the common name of teddybear cholla (chuh-oiy-ah). The mere though of falling into one of these bushes scares TPP. The spines have tiny recurved edges and they are hard to pull out, the branch segments have a tendency to fragment easily, so easily that some are called "jumping cholla". Should some animal carry one off, it could be pulled off at a distance where the segment can grow into a new shrub. These are just mean, nasty plants, although the flowers can be quite attractive.
