Blossfeldia
In addition to being the smallest, Blossfeldia is also the strangest of cacti, since its life cycle takes place similarly to that of lichens, remaining dormant for years apparently completely dehydrated, to then come back to life, grow and multiply with the return of availability of water. Blossfeldia colonize rock cracks on cliffs in Bolivia and Argentina.
