All angiosperms produce flowers and fruit, although some might not be things you would see as flowers or fruit unless you are a botanist.
Grass flowers and produces their fruit a botanist calls a caryopsis and most people call grain.
Wind pollinated trees have catkins or similarly nonflower-like inflorescences. Alders (Ulnus spp) have female ‘cones’ and tassel-like male catkins as their inflorescences. These are flowers as they have an enclosed ovary protecting the female ovule.
Maple tree fruit are the bladed samaras that twirl and glide through the air.

Cottonwood poplars (Populus deltoides) produce the white fluff that bears the fruit away with the wind. http://www.cas.vanderbilt.edu/bioimages/species/pode3.htm#Flower
