Carol, your seedlings are pretty! Congratulations! Generally, rose seeds are ripe about 110 or so days after pollination. Do you usually have about three and a half months from first bloom to when you should have the hips harvested in your climate? If that's pushing things, perhaps HTs aren't suitable for your goals. Ripening is more a function of time than color change. If you're basing ripeness on the hip color, you may have ripe seeds from hips that either won't genetically turn the expected color or which won't due to climatic conditions.
Jin, no worries. You don't have to want to create your own roses nor raise them from seed. It honestly isn't as difficult as some instructions make it sound. The things fall off rose bushes all over the world and germinate on their own, so how difficult must it really be?
I will happily let you know what I hear from Geoff. Keep your fingers crossed! Cl Columbia is doing just fine, thank you. I sent budwood of it along with the Annie Laurie McDowell, Grey Pearl and Kimo to Steve and he confirmed all the requested plants are budded, so he will be contacting everyone who ordered them within a few weeks.
