Both of these are from cuttings taken at Couples San Souci, Ocho Rios, Jamaica around 2 years ago. The top one is as prevalent as Petra is here in the US. I've been calling it "Kingston", as it gets not only the yellow and green you see here, but some red as well (the colors of the original Jamaican flag.) The bottom one is a slow grower, full sun, and has a very narrow, formal looking leaf. Thus, I've dubbed it "Tuxedo." If these are actually known varieties, please let me know. Thanks.
