Please look at the attached two pictures of our roses. We planted these rose plants outside about 2 months ago. The buds are starting to form, but when they get ready to turn into flowers, they look like this.
Do you have any ideas as to why this is happening?

Thank you for your question. The distorted buds are likely infested with one or more (of 15) known rose insect pests. (https://pnwhandbooks.org/insect/crop-pests?combine=rose). I suspect aphids are the culprit, and are described here: https://pnwhandbooks.org/insect/hort/landscape/hosts-pests-landscape-plants/rose-rosa-aphid
But, without specific evidence, through identification of the insect, we can't be certain. I suggest you dissect an effected bloom to search for more information, and let us know what you find. Thanks!
Thanks. We will look into it.
Welcome!
