sanguineum ssp. didymium

As above but with deep blood-red or black-crimson flowers in early to mid-summer. Said to prefer an almost alkaline soil but we have had little difficulty here at the RSBG. The leaves and branchlets are often more bristly than ssp. sanguineum. Found in SE Tibet and adjacent NW Yunnan, China from 14,000 to 15,000 ft. in rocky meadows and on limestone cliffs.

sanguineum ssp. sanguineum

Compact rounded evergreen shrubs. The leaves are smooth and often shiny above with a thin silver to gray  indumentum below.  The fleshy bell-shaped flowers (mid- to late spring) are extremely variable in color, ranging from deep blackish crimson to crimson, pink, yellow or white. An extremely variable species with numerous subspecific taxa.  Requires a well-drained and partially shaded to fairly exposed position.  Native to China (SE Tibet and NW Yunnan) from 10,000 to 14,500 ft. in various well-drained montane habitats.
