If it's not a pest problem, light, or water problem, and the roots are healthy, it's probably genetic. Last year some of the flowers on my Gerbera were also deformed. Billy Rae

I think any kind of anomaly that happens during the early stages of bud formation may cause this. It could be a genetic mutation, the weather conditions, some kind of insect infestation or a result of a chemical spray at the time when the buds are just beginning to form on the new growth. They're probably not even visible as buds yet. Sometimes the bloom will open and be perfectly normal but sideways. Other times the bud will produce a malformed bloom. I usually let them bloom to see what they look like out of curiosity. If you have a lot of them think back and see if you can figure out what was going on between 4 and 6 weeks ago that may have caused it.

Can you post pictures? I am not sure how to interpret what you meant by "deformed" blooms.

Don't have a clue what her parentage is. If I had to guess, based on her color, I would like to think maybe a relative of "Chicago Peace", Sport of the "Peace" rose. But this is only a guess. As far as I know, I did not gather hips from any roses white in color. "Chicago Peace" is as close as I could come via hips from Mother plant. Here she is in full bloom with a total of 16 petals: She has been clipped. I let her live for a day and she is now pressed in a book. I plan on making a bookmark out of her after she has dried out. Now for an update on the "Twin??", she has grown her 2 leaves mentioned in an earlier post and now has another 2 leaves sprouting... as before, both mirror like image once again. The last 2 leaves are kind of neat. They are growing almost vine like. Rather than outward they are growing more in-ward, toward the center: Have not noted any budding yet ... still waiting :o) Must mention two of my other seedling have also bloomed. They opened today: The first is white with a tiny hint of pink and a total of 6 petals. The 2nd is also white with a darker pink nearing more maroon in color, with a total of 5 petals. I am really crossing my fingers the 2nd might be a relative of "Tigress", oh, what a beautiful rose I find "Tigress" to be. Guess I will really never know for sure, but I can hope :o) Lionessrose
