Flowers? I suggest using some Bees for that. Those who see me post here often enough recognize that I'm a broken record when it comes to proposing a solution with bees, but this is actually the best case for bees.
Make a scoop(6 sticks and 1 wool) and find some hives. You'll want forest/meadows bees for this, but later on any kind will do if you are smart/careful. Then make either a apiary(or trade with a apiarist villager for one if he has that trade, or just steal his, and trust me, those bees in them are crap[but what would you expect from a Testificate Apiarist?]) if you have the stuff to spare, or if you're in a pinch, make a bee house(or twenty) with 3 wooden slabs, 5 wooden planks, and a honey comb(slabs on top, comb in the middle, boat shape with planks), and place those bees near some flowers(roses or flowers will suffice, BoP ones are harder to get to work in my experience), and assuming that they can work where you are(ideally a plains biome, as that is normal temp/normal humid, and both forest and meadows bees actually only work in those conditions unless bred to work elsewhere).
