The English translation for "25岁女高中相亲对象" would be "25-year-old female high school graduate seeking a相亲对象 (match/dating partner through an introduction)."

If you're specifically asking for the translation of "樱花" (cherry blossom), it would simply be "cherry blossom." However, this term wasn't directly included in your phrase, so I'm assuming you might have wanted to know about it separately.

Is there anything else you'd like translated or clarified?
