Hi Alberto, I've got 3 years invested in these Rhodophiala, so I'll follow your suggestion and sink the pots rather than bed them directly in the ground..."Better safe than sorry." Also, I understand now what you mean by 'taming'...or domesticating. Given their germination ratio (23:30) & speedy flowering (2 1/2 years), the R.montana already seemed very well suited to suburban Sacramento life. The others are soldiering on...but less so. R.splendens & R.advena also seem the hardiest by willing to continue to grow even when summer temps climb into the high F80s & F90s. I planted the seeds of the 2 alpine species (R.rhodolirion & R.andicola) together...and now there's only 1 seedling left standing...and I dunno which. Anyway, thanks again for the info & advice. - david
