I want to grow some flowers...

But I don't know which seeds are good to plant at this time of year. I tried to ask google but to be honest just got confuseing answers. It'd be nice to do up our garden even though we only have the house untill next august..and I am growing quite fast so the bump may make gardening awkward. But I still want to garden damn it. Doe's anybody know what flower seeds are good to plant in spring?
