Promethean plants indeed: Rosularia and their cognomen (more blasts, mostly from the past...)
|Prometheum (Rosularia) aizoon|
|Prometheum (Rosularia) chrysantha|
|Prometheum (Rosularia) hausknechtii|
|Prometheum (Rosularia) muratdaghensis|
|Prometheum serpentinicum with cacti and haworthia...|
|Prometheum (Rosularia) rechingeri|
Obviously closely allied to muratdaghensis, this smaller species has equally enchanting, colored rosettes, but smaller flowers and not quite as showy...after growing such masses for so long (which produced buckets of miniscule seed) I noticed it's almost gone from our collections...repeat after me: propagate! propagate! propagate!
|Prometheum (Sedum) pilosum|
|Prometheum (Sedum) sempervivioides|
|Rosularia sempervivum var. (very dwarf)|
|Rosularia sempervivum ex Urs Eggli coll.|
This one was paler pink than the rest and is quite persistent in the garden...
I end with a scan of a transparency I took in 1994 in Western Turkey, not far from Smyrna, that shows how rosularias grow in nature. Alas, this species is recalcitrant in cold winter areas, but the others we have grown successfully grow in similar situations in more central Anatolia.
I think a better name for the genus would have been Proteum: they are quite protean in their look, and more importantly, this removes the onus of eternal punishment on high, Caucasian cliffs. After all we're pampering them on miniature urban and suburban cliffs instead!
