The list above enumerates only plants which actually prefer 
rocky situations for their growth, and many of these will not 
succeed elsewhere. These do not, however, exhaust the avail- 
able native material for rock-garden purposes, and the fol- 
lowing list includes a large number of beautiful plants which, 
while not actually growing in rocky situations, are still suit- 
able for a rock 
garden.
