Well, RR, where do I begin? First off, where did you get those seeds? Ebay, perchance? I hate to break it to you but you may well have been scammed. There are some very unscrupulous dealers on there and others who bought seeds this way ended up with anything from roses to radishes. You need to know that roses DO NOT grow true to variety from seeds. There are a very few exceptions in the wild rose category that will self seed and grow true but all other varieties, especially modern hybrid tea roses like Osira, do not. Each individual seed will be it's own new variety. It may look similar to either of it's parents or it may look like any of the roses that went into the parents breeding but it will not be the same rose. So Osira seeds will not grow Osira rose bushes. The only ways to to grow roses true to their original variety is by rooted cuttings or bud grafting. Basically cloning. Secondly, not knowing exactly what your growing set up is, I will tell you that, for the most part, roses HATE to be inside. It is very difficult to produce the right temperature, humidity and light combination that will make them happy and thrive. I have tried many things and never succeeded in keeping even the small mini roses alive indoors for more than a couple of months. Barely long enough for winter to end and I can plant them outside.where they immediately perk up. I do hybridize roses and start my seedlings in January inside under lights during the winter. But as soon as it's warm enough for them to go outside they do! Sometimes that's as early as March if at all possible. They always struggle until they get out in natural sunshine and humidities and then they take off like gangbusters! If you'd like to know how I do my seeds send me a PM with your email address and I'll send you the paper I did for my rose society. Or go to the link below which is the Propagation forum and you'll find tons of info on how to grow rose seeds. There are as many ways to do it as there are growers, lol! Here is a link that might be useful: Propagation forum on GW

I am from India as well read some of the comments above, I have brought some roses from china which said black and white roses and rainbow roses, I know they are completely fake but the best thing is that even if a single rose grows from those seeds it will be a great success for me. Yes they are rose seeds as I can distinguish from their shape and size. They do need some cold period in fridge I have kept them in moist soil for 3 weeks nothing happened so I am now keeping them in fridge red white, orange whatever color they end up in I will be happy to accept.

I have an original knockout rose that I bought quite some years ago. It is the best knockout because the newer two (rainbow and pink) have no scent to speak of whereas the original knockout has a fine tea fragrance. It produces some fertile seed (and lots of large hips) through open pollination (but perhaps with rugosa). I've three or so of this years seedlings from it that have lived. The most vigorous of those has bloomed once earlier this spring and has a bud on it now (not bad for a several month old, one foot seedling). It is a nice single, red with a white center and a buff reverse and strong fragrance. It's quite healthy with more rounded, jagged leaves than the original with red tints.
