There is a Yeshiva named Pirchei Shoshanim.
I was trying to google it the other day using “Pirkei Shoshanim” and couldn’t find any match. There is a big difference in the words PIRKEI (פרקי)and PIRCHEI (פרחי ). The first is the plural of PEREQ or PEREQ meaning chapter, saying, as in the famous work “Pirkei Avot”. “PIRCHEI” with the letter CHET means “flowers of” or “blossoms of”, and this particular yeshiva could be called “blossoms of roses” (or maybe even “rosebuds”?).
Anyway, if you are googling, and you came across this article, perhaps you are looking for the Yeshiva here: http://www.shulchanaruch.com. It’s other name is Yeshiva Pirchei Shoshanim, or the “Shulchan Aruch Project”.
If you are unfamiliar the “Shulchan Aruch” (or Aruch Ha-Shulchan), it is described as: (Hebrew: שׁוּלחָן עָרוּך, literally: “Set Table”) also known as the Code of Jewish Law, is the most authoritative legal code of Judaism. It was authored in Safed, Ottoman Eyalet of Damascus, by Yosef Karo in 1563 and published in Venice two years later. Together with its commentaries, it is the most widely accepted compilation of Jewish law ever written.
Interesting enough, I checked Google on 12/08/2013, and it now notices that PIRCHEI is similar to PIRKEI, and says “Did you mean:” or “Showing Results for:” PIRCHEI SHOSHANA. So Google somehow learned that people got these words mixed up, maybe this blog helped in sum small way.
