First found in California in 1925 (J. T. Howell 1942), Crassula tillaea is now widespread and locally common, often mingling with C. connata. It has been spreading northward, being first found in Oregon in 1984 (D. H. Wagner 1991), in Washington in 1999 (A. L. Jacobson et al. 2001), and in British Columbia in 2002 (P. F. Zika 2002); it has not yet been found growing with C. connata in this part of its range (A. Ceska, pers. comm.).
