I'm sorry to hear! Were you looking for greenery and just photos in an outdoorsy with plants and flowers type of feel? If so then maybe you can find a place that has a greenhouse to take photos that way you get some greenery and flowers?
Check weather.com for hourly updates. You may get a break in rain for an hour to get photos. cloudy/stormy photos look awesome! If not grab a clear umbrella and take some romantic rainy photos! Also it's good luck!
