I only have Gold Glow of the three and just got it last year so don't have a lot of info. It's a pretty buttery yellow if I remember correctly. I don't remember any real fragrance and I spray regularly so bs isn't too much an issue with me. : )
April

Eclipse and Mojave are blackspot magnets here; the blooms have great form in bud but they lack the number of petals to make the bloom last. Mojave I keep just for the color, there isnt another HT, old or new, that has the same blend of tones. Eclipse has truly been "eclipsed" by better yellows and I keep that one just for sentimental reasons

Thank you very much for your info. I have bad BS problem and I don't spray so I want to avoid any that might be a disaster later. The pictures of Gold Glow look so pretty that I am very tempted. April, do you have Julia Child? If you do, how does Gold Glow compare to JC? Many seem to think Julia Child is the best yellow. GG seems to have larger flower from info on helpmefind.

I got a Sonia from S&W greenhouse last month. I saw a body bag last night and bought it. The canes looked very good and it hasn't broke dormacy. I planted it this morning in a pot. One striking difference between the two is definetely the roots. I have planted body bags before but never noticed how badly the roots were prunned to fit the bag. The two Sonia actually have very similar tops, but the one from S&W definetely has larger roots. I had no problem soaking the body bag rose but some of the ones I got from S&W have such big roots that I had problem fitting the whole plant into the containers that I use for soaking.

Eclipse was the first rose I ever shovel-pruned and Gold Glow was the third. There are many, many better yellow roses on the market but since I don't have blackspot to contend with, I hesitate to make recommendations. Personally, though, I love Michaelangelo, Julia Child, Eureka, Radiant Perfume and Easy Going. While I also grow Gina Lollobrigida, she has so many petals that the blooms may ball in your zone.
