You cannot imagine how happy I am to learn about Daybreaker and Colorific, and I just found a source for a tree rose of Daybreaker that I'd hoped to find for next spring shipping! It is my favorite of all the roses I've seen to date, so it is wonderful to have it ID's and available. Really, heavenly, after two years of searching and coming up with nothing.
Now that I know what it is, I have just read that it is disease resistant but, on a private blogger's site, that it is prone to rust in her garden. I'll have to learn more, as I'm a complete newbie to roses ... but I can't imagine a more beautiful flower to get me started learning about rose care, either way.
Thank you so much for this fabulous help!
