Scientific Name 

Dudleya blochmaniae (Eastw.) Moran ssp. blochmaniae          

Family 

Crassulaceae

General

     A rare species with three subspecies.   The subspecies native to habitats around CI is found on rocky, north facing slopes, sometimes in great local abundance.                                          

CI

This tiny succulent is one of the treasures of the wild areas of CI.  The subspecies found at CSUCI is D. blochmaniae blochmaniae, still rare, but the most wide-spread of the three subspecies.  In the proper habitat around CSUCI, it is thriving, in fact, can be locally abundant.  The tiny white flowers of one patch above University Glen from a distance look like a thin dusting of snow (in June!). It grows from rocky soils, and from any crack or pit in a rock face that is large enough to catch a little soil.  It is often associated with pads of moss or patches of Selaginella growing from rock faces.

Tiny plants appear shortly after the first rain in October or November.  Flowering is relatively late, May-June.

While not officially protected by state or federal statute, this species is rare and special.  Care must be taken to avoid damaging it habitat. Fortunately around CI, all of this habitat occurs in relatively inaccessible, or at least seldom trod, hillside areas.
