Hi, sssaskia. You new phals are very lovely indeed.
The Sogo Grape is a gorgeous flower, and blooms over a long period of time, continuing to put out flowers on an existing stem. Yours is an especially glossy and beautiful color.
About Brother Sara -- I don't believe there is a Brother Sara Lee. It's just Phal Sara Lee (and one of the parents of Brother Sara Gold). So yours is probably Brother Sara Gold-- it's been offered quiite a bit over the last year. Flowers on Sara Gold are very long lasting-- one flower blooms for several months.
